I am not a student of biology,in other words I have not read biology much.

But I read that plants have life and so my question is the following:

Suppose I take two saplings of two different varieties of hibiscus(or any other tree variant) and I put them in the same pot and allow them to grow up. Suppose they grow up and become well grown plants after say 4-5 months. My question is:

Will the two saplings experience any feelings for each other,in other words will they become friends or share any relation with each other. Suppose one of them is attacked by insects and its growth gets shunted,will the other plant also experience some feeling for it.

If I uproot one plant will the other one feel lonely or any other kind of feeling as if its counterpart is missing.

If someone cares to answer the above questions,I would be very grateful. Thank You

Wikipedia defines emotion as "any conscious experience characterized by intense mental activity and a certain degree of pleasure or displeasure."

Plants do not have a central nervous system and therefore no mental activity so they certainly don't have emotions in the sense that humans and animals can have emotions. However plants feel/detect being eaten and they can communicate this to other (related) plants by releasing volatile organic compounds.

Do Plants Feel Pain?

Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry. However, it seems that many plants can perceive and communicate physical stimuli and damage in ways that are more sophisticated than previously thought.

Some plants have obvious sensory abilities, such as the Venus flytrap and its incredible traps that can close in about half a second. Similarly, the sensitive plant rapidly collapses its leaves in response to touch, an adaptation that might serve to startle away potential herbivores. While these plants visibly display a clear sensory capacity, recent research has shown that other plants are able to perceive and respond to mechanical stimuli at a cellular level. Arabidopsis (a mustard plant commonly used in scientific studies) sends out electrical signals from leaf to leaf when it is being eaten by caterpillars or aphids, signals to ramp up its chemical defenses against herbivory. While this remarkable response is initiated by physical damage, the electrical warning signal is not equivalent to a pain signal, and we should not anthropomorphize an injured plant as a plant in pain. Plants have exceptional abilities to respond to sunlight, gravity, wind, and even tiny insect bites, but (thankfully) their evolutionary successes and failures have not been shaped by suffering, just simple life and death.

Health and well-being benefits of plants

Concentration and Memory. Being around plants helps people concentrate better in the home and workplace. Studies show that tasks performed while under the calming influence of nature are performed better and with greater accuracy, yielding a higher quality result. Moreover, being outside in a natural environment can improve memory performance and attention span by twenty percent.

Keeping ornamental plants in the home and in the workplace increases memory retention and concentration. The calming influence of natural environments is conducive to positive work environments by increasing a person’s ability to concentrate on the task at hand. Work performed under the natural influence of ornamental plants is normally of higher quality and completed with a much higher accuracy rate than work done in environments devoid of nature. Going outside or being under the influence of plants can increase memory retention up to twenty percent, a recent University of Michigan study showed (Sewach). The effect of nature in the home and in the workplace serves to stimulate both the senses and the mind, improving mental cognition and performance.

Educational Programs / Special Events. Parks and botanical gardens often play host to educational programs and special events, which contribute to the cultural awareness and education of the community (children especially). This raises environmental consciousness and appreciation.

Installing a park or botanical garden in a community has many direct benefits to residents, but an auxiliary benefit of having such a naturalized landmark in the community is the special events and cultural opportunities it brings to people who might not otherwise be exposed. Botanical gardens and zoos often create educational programs for children in order to teach them how the value of being environmentally-conscious and conserving the environment. They can also impact adults in the community as well, creating a cultural awareness of the importance of natural environments. Parks and gardens foster an appreciation for nature that often instills in residents a sense of responsibility for the caring of and protection of the environment. (Appleseed, Inc. 2009, Dubey 2007, Nadel 2005, Phipps Botanical Gardens and Conservatory 2010)

Flowers Generate Happiness. Having flowers around the home and office greatly improves people’s moods and reduces the likelihood of stress-related depression. Flowers and ornamental plants increase levels of positive energy and help people feel secure and relaxed.

Keeping flowers around the home and in the workplace greatly reduces a person’s stress levels. Natural aesthetic beauty is soothing to people, and keeping ornamental flowers around the home environment is an excellent way to lower levels of stress and anxiety. People who keep flowers in their home feel happier, less stressed, and more relaxed. As a result of the positive energy they derive from the environment, the chances of suffering from stress-related depression are decreased as well. Overall, adding flowers to your home or work environment reduces your perceived stress levels and makes you feel more relaxed, secure, and happy. Flowers can help you achieve a more optimistic outlook on your life, bringing you both pleasing visual stimulation and helping you to increase your perceived happiness.

Health and Recreation. Access to parks and recreational activities is positively correlated with rates of physical activity, which improves mood and contributes to overall healthiness. Health care costs are subsequently reduced.

Parks and urban green spaces impact people’s health by providing them with an inexpensive (often free) and convenient recreational service. There is a positive correlation between the presence of a park in a neighborhood and the level of physical activity of the residents people are much more likely to exercise when there is a no-cost, aesthetically pleasing area or facility for them to use. As a result, residents of neighborhoods with beautiful parks are much healthier their increase in exercise makes them less susceptible to physical ailments and more resilient against minor illnesses. As a result, these residents do not spend as much each year on health care and medical treatment, because they require fewer of these services Healthy people are happier people residents who exercise often have excellent overall health and therefore have a more positive mental outlook. The presence of parks in neighborhoods encourages residents to exercise, thus improving their physical state and enabling them to more fully enjoy their lives.

Accelerates Healing Process. The presence of plants in hospital recovery rooms and/or views of aesthetically-pleasing gardens help patients to heal faster, due to the soothing affects of ornamental horticulture.

Shrubs, trees, and flowers have a practical application in hospitals: the presence of plants in patient recovery rooms greatly reduces the time necessary to heal. The soothing effects of ornamental flowers and plants are so great that simply having daily views of flowers and other ornamental plants in landscaped areas outside patient recovery room significantly speed up recovery time. Another technique to decrease recovery time is horticulture therapy, where patients care for and nurture plants themselves. Patients who physically interact with plants experience a significantly reduced recovery time after medical procedures. (Brethour 2007, Frank 2003, Friend 2008, Lohr 2000, Park, 2009, Pennsylvania Landscape and Nursery Assn. 2009, Ulrich 1984)

Improves Relationships/Compassion. Research shows that people who spend extended lengths of time around plants tend to have better relationships with others. This is due to measurable increases in feelings of compassion another effect of exposure to ornamental plants.

Ornamental plants affect the levels of compassion that people feel for others. Studies have shown that people who spend more time around plants are much more likely to try and help others, and often have more advanced social relationships. People who care for nature are more likely to care for others, reaching out to their peers and forming shared bonds resulting from their common interests. Extended exposure to nature and wildlife increases people’s compassion for each other as it increases people’s compassion for the environment in which they live. In short, being around plants can help to improve relationships between people and increase their concern and empathy toward others. (Brethour 2007, Etcoff 2007, Frank 2003, Hagen 2009, Haviland-Jones 2005, Pohmer 2008, Rappe 2005)

Improved Human Performance/Energy. Spending time in natural environments makes people better at doing their jobs. It also increases energy levels and feelings of vitality.

Spending time in nature gives people an increased feeling of vitality, increasing their energy levels and making them feel more animated. Their performance levels are, in turn, increased by this improved state of mind. Natural environments induce a positive outlook on life, making people feel more alive and active. When people experience increased vigor, they put more of themselves and their energy into their work. Plants can help people to improve their performance at work and at home by increasing their perceived vitality and giving them more feelings of added energy. (Bernstein 2009, Brethour 2007, Bringslimark 2007, Dravigne 2008, Etcoff 2007, Kaplan 1995, Kuo 2001a, Pennsylvania Landscape and Nursery Assn. 2009, Rappe 2005, Shoemaker 1992, Univ. of Rochester 2010)

Learning. Research shows that children who spend time around plants learn better. In addition, being around natural environments improves the ability of children with Attention Deficit Disorder to focus, concentrate, and engage more with their surrounding environment.

Keeping plants in a child’s learning environment enhances learning capabilities by helping them to focus and concentrate. This improves their ability to learn new things and makes it easier for them to absorb and retain information. Ornamental plants are conducive to generating a positive learning environment, reducing children’s tendency towards distraction and helping them to be better able concentrate on school work. Specifically for children with problems paying attention, adding plants to the classroom can have a dramatic positive effect on the way they learn. For example, children with Attention Deficit Disorder, learning in a natural environment can help them to engage more in the classroom, improving their focus and concentration on the task at hand. The soothing effects of natural aesthetic beauty help to minimize the distractions that would otherwise occupy their minds. By altering the environment in which children learn, plants can help them to learn better. (Faber Taylor 2001a, Frank 2003, Kellert 2002, Kuo 2004, Lieberman 1998)

Medicinal Properties. Cultivating plants is beneficial to humankind because of the many medicinal properties of trees and foliage plants.

One of the more obvious benefits of plants and trees is that many of them have valuable medicinal properties. Cultivating plants helps humanity because it provides opportunities for additional scientific studies of the possible positive medicinal values of plants. Natural herbal remedies are simple and holistic methods for treating common illnesses and maladies. Some can be made in the home and are a natural way to treat minor complaints. By cultivating plants we can continue to cultivate our knowledge of the natural world and arm ourselves with more defenses against disease and infection. (Brethour 2007)

Mental Health. Studies have proven that people who spend more time outside in nature have better mental health and a more positive outlook on life.

People who spend more time outside in nature have a significantly more positive outlook on life than people who spend a great deal of time indoors. Communing with the natural world increases people’s feelings of vitality and energy, and consequently has a large positive effect on their overall mental health. Being outside around trees and ornamental horticulture is proven to improve people’s mental health, and give them a more positive outlook on their lives. People who spend time outside every day are less likely to be depressed or stressed, and thus have fewer burdens on their mental health. (Barnicle 2003, Faber Taylor 2001b, Grinde 2009, McFarland 2010, Morikami Museum and Japanese Gardens 2009, Shoemaker 2009, Wolf 2004b)

Perceived Quality of Life. People associate beautifully landscaped areas with a higher quality of life. This is important in attracting businesses and sustaining growth in the community.

Beautiful natural landscapes not only improve the aesthetics of the community, they also affect resident’s perceived quality of life. People associate living in areas with a great deal of natural beauty with a higher quality of life. A high quality of life, in turn, benefits the entire community, because residents spend more money and positively affect the economy and social pulse of the town and can also attract new businesses. Thriving communities are ones in which natural beauty is appreciated as a part of an overall high quality of life, which is why installing landscaping is crucial to both the success and happiness of the individual and the public. (Brethour 2007, Bisco Werner 1996, McFarland 2010, Nadel 2005, Phipps Botanical Gardens and Conservatory 2010, Wolf 2004b, Younis 2008)

Reduce Community Crime / Community Cohesion. Neighborhoods with beautiful parks tend to have less crime. This is due in part to the effect that parks have on a community parks give people a reason to come together and become a tight-knit community. People who care about their neighborhood parks are much more likely to get politically involved when businesses threaten to downsize them. Increasing political activism in the community is another positive outcome of cultivating a love for neighborhood parks.

Neighborhoods with beautiful parks and landscaping have reduced crime rates. This is due to the increase in community cohesion that occurs as a neighborhood rallies around a beautiful local landmark. When residents feel greater pride in the beauty of where they live, they are much less likely to detract from it (either by graffiti or endangering people within it). Communities that choose to clean up their parks and beautify crime-ridden neighborhoods have less crime and fewer criminals to deal with. Parks can positively affect the community be reducing criminal acts and bringing residents together. Cohesion in the community is critical to the success of the community as a whole, and this can be achieved through unifying people around a park or botanical garden. Parks decrease incentives for people to commit crimes in the community, and at the same time help to bring neighbors together. They can also increase local political activism. As businesses and urban expansion threatens to downsize parks in the community, more and more people are banding together in a political effort to save their parks. Parks inspire people to come together and fight for what they know is holding them together as a community.

Reduce Stress. Studies show that people who spend time cultivating plants have less stress in their lives. Plants soothe human beings and provide a positive way for people to channel their stress into nurturing .

Participation in gardening and landscaping activities is an effective way to reduce levels of stress. Studies have shown that people who nurture plants and garden have less mental distress than others. Gardening provides people with a positive way to channel their stress and frustration into something beautiful that provides them with comfort and joy. Part of the effects of gardening come from the satisfaction people get from nurturing and helping a living thing grow. Plants and gardening soothe people because they help them turn their stressful feelings into something positive which gives them pleasure. By helping them transform their stress into a more positive emotion, gardening also gives people an excellent coping mechanism for their daily frustrations. Nurturing plants reduces stress levels and gives people a way to cope with their negative feelings. (Mitchell, 2008, Brethour 2007, Bringslimark 2007, Frank 2003, Kohlleppel 2002, McFarland 2010, Pohmer 2008, Ulrich 1991, Waliczek 2000)

Therapeutic Effects of Gardening. Gardening can act as therapy for people who have undergone trauma. The act of nurturing something is a way for people to work through the issues surrounding traumatic events and improve their mental health.

Gardening can have therapeutic effects on people who have undergone trauma, either mental or physical. The act of nurturing a plant can provide victims with a way to work through their issues and heal their wounds, whether they are on the surface of the skin or deeper. Cultivating plants also improves their mental states and helps to put them in a better place for recovering. Gardening is a therapeutic tool that can be used to help put people in a better psychological state during recovery and help them to work past the mental barriers that could impede their healing. (Aldous 2000, Barnicle 2003, Brethour 2007, Collins 2008, Morikami Museum and Japanese Gardens 2009, Pohmer 2008, Rappe 2005, Stoneham 1995)

Traffic Safety / Driver Satisfaction. Beautifying road ways can have the dual effect of increasing driver satisfaction with the roadside landscape and creating a natural median. Drivers are much less likely to accidentally drive over a median if there is a landscaped area between oncoming lanes of traffic.

Beautifying traffic medians not only improves the aesthetics of the roadways, it also affects driver attitudes. Studies show that drivers are more at ease on roadways with natural landscaping, and are much more inclined to think positively about the community that they are driving through if the roadways are beautiful. Furthermore, adding trees to roadways creates a sort of natural obstruction which could reduce the likelihood of cars crossing medians into oncoming traffic lanes. This improves driver safety and makes the community a safer place for everyone to live in. Landscaped areas between oncoming lanes of traffic could decrease the number of accidents occurring due to drivers crossing the median and make the road a safer place. (Wolf, 2001b, 2001c, 2006)

Upgrade Effect. As parts of the community begin to improve their urban green spaces, other areas will be forced to stay competitive and beautify their areas as well. The upgrade effect benefits the entire community, as neighborhoods and businesses encourage each other to landscape and beautify the community.

As more businesses and neighborhoods take on the task of beautifying their surroundings, other competing areas will be forced to follow suit. In other words, as a community works to better itself, other parts of the area will be forced to upgrade as well to keep drawing people in this phenomenon is known as the upgrade effect. The upgrade effect positively affects everyone, because it keeps communities from ignoring the benefits of landscaping and developing green spaces, it forces competition and keeps the area looking beautiful. Neighborhoods will be encouraging each other to keep beautifying the landscaping, setting off a cycle of self-improvement that has positive ripple effects outwards to all sectors of the community. (Bisco Werner 1996, Brethour 2007)

Do plants feel pain?

Few moments evoke a sense of summer like catching a whiff of freshly cut grass. For many people, it's a pleasant sign that warmer temperatures are here to stay. For the grass, however, this scent signals an entirely different story.

The smell we associate with freshly cut grass is actually a chemical distress call, one used by plants to beg nearby critters to save them from attack (usually it's an affront by insects, but in this case, it's lawnmower blades). After all, when danger strikes -- whether it's landscaping equipment or a hungry caterpillar -- plants can't lift their roots and run. They must fight where they stand.

To protect themselves, plants employ a volley of molecular responses. These chemical communications can be used to poison an enemy, alert surrounding plants to potential dangers or attract helpful insects to perform needed services [source: Krulwich]. Sometimes, a plant's molecular defense plays double-duty. For example, plants that produce caffeine use the chemical as self-defense, but it also gives bees a caffeine buzz. The caffeinated bees treat the plant like it's the corner coffee shop, returning again and again and leaving their pollination services as payment.

Clearly, plants can communicate. But does that mean they can feel pain? It's a troubling scenario for salad lovers squeamish at the thought of eating foods with feelings, and for them the answer may not be that appetizing.

According to researchers at the Institute for Applied Physics at the University of Bonn in Germany, plants release gases that are the equivalent of crying out in pain. Using a laser-powered microphone, researchers have picked up sound waves produced by plants releasing gases when cut or injured. Although not audible to the human ear, the secret voices of plants have revealed that cucumbers scream when they are sick, and flowers whine when their leaves are cut [source: Deutsche Welle].

There's also evidence that plants can hear themselves being eaten. Researchers at the University of Missouri-Columbia found that plants understand and respond to chewing sounds made by caterpillars that are dining on them. As soon as the plants hear the noises, they respond with several defense mechanisms [source: Feinberg].

For some researchers, evidence of these complex communication systems -- emitting noises via gas when in distress -- signals that plants feel pain. Others argue that there cannot be pain without a brain to register the feeling. Still more scientists surmise that plants can exhibit intelligent behavior without possessing a brain or conscious awareness [source: Pollan].

As they grow, plants can alter their trajectories to avoid obstacles or reach for support with their tendrils. This activity stems from a complex biological network distributed through the plants' roots, leaves and stems. This network helps plants propagate, grow and survive. Trees in a forest, for instance, can warn their relatives of insect attacks.

One scientist injected fir trees with radioactive carbon isotopes and saw that within a few days the carbon had been sent from tree to tree until every tree in the 30-meter-square area was connected. The scientist learned that the mature trees "communicated" to the network to share nutrients through their root systems to feed nearby seedlings until they were tall enough to take in light for themselves [source: Pollan].

Talking to Plants

The purpose of this experiment is to learn whether talking to a plant will help it grow.

  • How do plants communicate?
  • What types of plants communicate with each other?
  • What types of messages do plants send to each other?
  • How do vibrations affect plants?
  • Is it possible for plants to sense chemical messages sent by other creatures?
  • Do humans communicate through chemical signals as well?

Many people talk to their plants while they water them. Usually, people who talk to their plants believe that plants can pick up on their good intentions. This is a relatively common practice, as human beings tend to anthropomorphize, or give human qualities to non-human life forms or objects. While there is no evidence to suggest that plants respond to affection, some plants do have a limited ability to communicate with one another. Though plants lack the ability to receive and process sound waves, evidence suggests that some plants can communicate with each other through the use of chemical signals. Additionally, vibrations that travel through the soil or in the air may have an effect on plant growth. It may be possible for plants to pick up on the vibrations created by human speech and maybe even by the chemical signals that humans release without knowing it.

The rise of the ‘plantita’: Plants have feelings, too, like pets

First came the home-cooked meals and baked goods. Now, the stay-sane-at-home movement has found its newest preoccupation: growing plants.

People have been turning their homes into green sanctuaries. Our feeds have been flooded with photos of proud plant parents and their leafy babies. They call themselves “plantitos” and “plantitas,” a portmanteau of plant and tito (uncle) or tita (auntie).

Some choose cacti in pretty tiny pots, others like indoor plants with giant leaves. There are others who prefer edible plants like herbs and vegetables. The reasons they choose to grow plants vary.

There are varying degrees of being a plantita, too. Some have pots in the corner while others have an indoor jungle. Here they share tips for the budding plantito or plantita in you.

Gretchen Fullido, TV anchor

I got into indoor gardening when I moved into my new place in 2017. I was also going through a lot at that time and taking care of plants was very therapeutic for me. Having greens inside the house changed the vibe of my home. It helped me with my mental health and gave me a sense of calmness. Back then, seeing new leaves grow gave me a sense of fulfillment and happiness.

I soon started propagating my plants. Now my home is literally an indoor jungle. Every angle and corner of my home is filled with plants. I even had to take out things and furniture because I wanted more plants to occupy my space. It also helped me let go of unnecessary things at home. Taking care of plants really shifted my outlook in life and gave a whole new meaning to it. I also met so many new friends and kind souls from the planting community.

I have so many plants. I collect monsteras, all varieties, but my favorites are deliciosas, borsigianas and adansoniis. I also have a huge yucca, a giant cactus, giant alocasias, giant pothos, rubber trees, fiddle leaf figs, philodendrons, anthuriums, begonias and more. I do short video tutorials for care and treatment, DIY stuff and ideas and I share my experience with my plants on social media.

My tip is to do your research first before buying a plant. Check if you are willing to exert time and effort on your plants because they are alive and they all need TLC. Start with low-maintenance plants, then work your way up. Don’t just get a plant because it’s in and trendy. Follow your heart and build a connection with your plants. I really believe that when you’re looking for a plant, your heart will skip a beat when you find it.

Abby Asistio, singer-songwriter, host and alopecia awareness advocate

I started really getting into plants during the lockdown. Went through a not-so-good season last May and what started as an initial distraction has now turned into a constant source of joy, peace, happiness and relaxation.

The first plants I took care of were a bunch of ZZ plants, which I also learned to propagate. I now have a growing collection of pothos, calatheas, sansevierias and caladiums. Some of my favorites: sensation plant, areca palm, peace lilies and wandering Jew.

One of my biggest lessons when it comes to growing plants is to not be too hard on myself when some of them don’t make it. I know it’s hard to accept and let go when they die after you’ve given them much love, care and attention. It’s OK to feel sad over them, but that doesn’t define your identity as a plant parent. Instead of dwelling on the heartache, focus your energy on the ones that are still alive, and celebrate new growth when they happen.

Carol Rosales, ESL teacher and trading business partner

My unit is beside the swimming pool and the sun’s rays get inside. So usually, the temperature is always humid. My only way to at least make the place a bit cooler is to grow plants inside. Eventually, it became a hobby. I started long before the fad of plantitas during pandemic.

I am fond of the sansevieria family. Whale fin, snake plant, worm type. They are great for my interiors, and my children usually benefit from the protection they give against radiation from gadgets and PC at home. I have one alocasia at the very corner.Plants are wonderful for the interiors, too.

Patience and effort are key. They are like pets. They need to be nurtured regularly. They give happiness but they also cause heartbreak when they become gloomy.

Micha Billones, lawyer

Like most people trying to survive being locked down in their homes during a pandemic, I, too, looked for a new hobby to immerse myself into. My heart ultimately led me to greener pastures. I became a plantita!

It started out with collecting indoor plants until I decided I was ready to get my hands dirty and grow myself some herbs. I have indoor plants, succulents, a few outdoor plants and my oh so favorite babies: herbs!

Don’t buy plants on impulse. Do your research to know whether a specific plant suits well with your living conditions. Learn how to care for it. For new plant parents, start caring for the basic ones (snake plant, ZZ plant, etc.) before progressing to relatively challenging ones like calatheas.

Bei Hubines-Demasiado, Bal’s Garden landscape artist

Planting was a form of punishment from our father. He would make us plant on weekends to prevent us from seeing our friends. Through the years, we learned to love what we do. We developed a green thumb, too. Now, we are landscape designers. Plants have feelings, too, so when they feel the love and care that you give, they will surely grow lovely and healthy as you want them to be.

Gina Villahermosa’s son in their home garden

Gina Villahermosa, teacher

When we moved into our forever home, I wanted to landscape our front yard. But I knew we couldn’t afford to pay a landscape artist. When the pandemic started, I suddenly had a lot of time on my hands that allowed me to work on the landscape of our house myself. It’s a wonderful way that helped me cope with stress and fear.

I started with vegetables that we grow on the side of our house, and my son helps me water them. Then I went to cacti and succulents. I propagate and grow them. It eventually became a business. For beginners, choose a common plant like rose cabbage, Black Prince and haworthia. They’re inexpensive and you won’t feel bad if they die on you. INQ

Do Plants Experience Pollution? Will Plants Grow More or Less or be Unaffected when Grown in Polluted Soil?

To determine whether plants experience pollution. Will plants grow more or will they be unaffected when planted in polluted soil?

Research Questions:

  • What is photosynthesis?
  • Under what kinds of conditions will most seeds germinate?
  • What are some of the substances that can pollute the soil?
  • What do scientists know about the effect of oil in the soil and its impact on plant germination and or growth?
  • Is the ph of the soil a critical factor in plant growth?
  • What is the ph of ordinary household vinegar?

On the information level, this experiment serves to acquaint students with current information on the conditions under which plants grow. The worlds of plants and animals are interdependent. We depend on plant life for our food, our clothing our shelter, our medicines. In brief we need plants to support our life cycle. Unfortunately in our continued efforts to improve our way of life, we have to some degree polluted our environment, our water, our air and our soil. Today great efforts are made to reduce the pollution in terms of all of our natural resources. In this project, we attempt to determine the effects of possible pollutants of our soil. Will soils that are contaminated with heavy oil or with acidic vinegar or with caffeinated coffee have a direct negative impact on plant growth or conversely will they serve as stimulants to plant growth. In experiments with tree growth, pollutants were detrimental to growth. In the case of the plants you have chosen let us discover if this is the case. Good luck!

This science fair experiment also serves to acquaint students with the essential processes of sciencing such as the importance of the use of a control, of identifying dependent and independent variables, of data collection, of pictorial and or graphic presentation of data and of being able to make better judgments as to the validity and reliability of their findings. They take on the role of scientists and in the process they learn to act as one.

These include: a package of seeds of sunflower or alfalfa or radishes, planting pots, top soil, a measuring cup, water, a watering cup, a can of heavy motor oil, instant dry caffeinated coffee, and a bottle of white vinegar, metric ruler, labels, tape, a pencil and a camera.
  2. Copy both the Observation Chart (making 7 copies) and the Summary Chart (making 1 copy).
  3. Record your hypothesis. What predictions can you make? Which of the plants will survive? All or some and on what basis did you make the prediction?
  4. Fill your 8 planting pots with top soil. Each with the same amount. Read the directions on your seed package and plant the seeds as directed. Place the same number of seeds in each pot. Water as directed and place in a dark place for germination. Check for amount of time needed for germination. If you plan to supplement your observations with photos, start taking pictures now.
  5. When the seeds have germinated, inspect to see that you have the same number of seedlings in each pot. If not, weed some out.
  6. Now label the plants placing 2 plants in each category or group. Start with the controls. These plants will remain in uncontaminated top soil and therefore are labeled Control #1 and Control #2. We are being very safe in having 2 plants in each group in case one dies, we still have the other. Now, continue to label the groups of two plants as #1 and #2 +oil, #1and #2 +vinegar and #1and #2 plus coffee (caffeine). Our soil pollutants are oil, vinegar and caffeine. Will plants grow in these pollutants? Let us find out.
  7. Take each group of plants and add the contaminants, placing one tablespoon of each contaminant as designated on the label, adding a tablespoon of oil, of vinegar, of dry, instant caffeinated coffee and of course, nothing to the controls. You have now contaminated 6 plants.
  8. Place all 8 plant pots in full sunlight for the next 14 days watering them with equal amounts of tap water.
  9. Every two days, observe each group of plants and record your findings on the Observation Chart. You may also take photos.
  10. Review the data in the Observation Chart and average and summarize your results in the Summary Chart.
  11. Write your report. Make certain to include all of the research you conducted, all of the data as well as photos and the bibliography .You may want to go a step further and state what you think are some of implications of your results for direct application in growing plants.

  1. Plant four corn seeds in each of the soil cups. Make sure they’re evenly spaced, and plant them just a half inch under the dirt.
  2. Create labels for each of the following using a sticky note, and stick to one of each soil cup:
    1. Control
    2. Tip
    3. Base
    1. Shoot cap: Cut a small 2″ x 3″ square of aluminum foil. Wrap it around the tip of a straw to create a small, closed-ended metal cap, and slide it off. This will be placed over the tip of the growing shoot to cover any light coming in to the tip.
    2. Base sleeve: Cut a small 1/2″ x 3″ square of aluminum foil. Wrap it around the middle of a straw so it creates a small open-ended 1/2″ tall tube, and slide it off. This will be placed around the growing shoot so that it can grow through it.

    If the experiment worked correctly, you should have noticed that the seedlings that were covered with caps at the tip grew straight up, while the control seedlings and the seedlings with the bases covered bent towards the light. This is phototropism in action.

    Darwin correctly concluded that plants are able to “see” light using the tips of the plant shoots, rather than through the stalks. It wasn’t until a bit later that scientists figured out exactly why that was, though.

    It turns out that plants are able to grow by using hormones such as auxins and gibberellins. Auxin in particular tells individual cells to reach out and grow longer, like Stretch Armstrong. It’s one of the ways that plants grow taller. Normally, plants growing with an unshaded light source will grow straight up towards the sun because auxin is evenly distributed all around the shoot.

    But when the light is heavily shaded and comes in from an angle, something interesting happens. Auxin starts to concentrate on the shaded side of the plant instead, and as a result, the cells on the sunny side stay the same size but the cells on the shaded side grow longer. This causes the plant to tip and grow towards the light.

    Auxin is primarily produced in the tips of the plants. This is why the plant grew straight up when you covered the tip with a cap—it couldn’t “see” the light anymore! The tips of the control seedlings and the seedlings with the bases covered could still sense the light, so they grew towards the sunlight.

    Thanks to Charles Darwin and modern science, the mystery of how plants grow towards light was finally solved.

    I want to teach you something about science. Science is a collection of observations about the world. When something has been observed enough, it becomes scientific law. That means that scientists say that what they have observed will always be true. It is stated as fact. But even these “laws” have been broken at times when all of a sudden, something different is observed. It was previously believed that the atom was the smallest thing in the universe. It was called fact. Then someone figured out how to split an atom. The point is that science only really tells us what has been observed. It doesn’t prove truth. It just states what is observed and measured in the world around us. Why am I making sure you understand this? Because who was there to observe the creation of the universe? God alone. Science can’t prove anything about the creation of the world because it can make no observations about it. It takes what it observes in the world today and makes hypotheses, guesses, about the creation of the world. Until pretty recently most Western scientists were Christians. Never let anyone make you feel stupid for believing God created the world. Many scientists that you read about in history believed in a Creator, and they were some of the smartest people that have ever lived. The Bible contains all truth. You never have to be afraid to believe the truth in the Bible. There may seem to be things that couldn’t possibly be true. For example, scientists have determined that stars are billions of light years away. That means that in order for us to see a star’s light, that light would have had to be traveling for billions of years to reach us. Well, a Christian mathematician and scientist has shown how it could appear that way and still only be less than ten thousand years away. No one has yet been able to dispute the math he used to show it. Here’s an article about it that your parents might be interested in. One method science uses to try and observe the age of something is carbon dating. There are some who say carbon dating shows that there are bones which are millions of years old. Here are two articles that talk about how carbon dating isn’t accurate. These are articles for adults. You don’t have to read them. The first is much easier to read than the second, but if you or your parents are interested, please go ahead and read them. I just want to show you that there are scientists that believe the earth is young. I personally know a scientist, a physicist with a PhD, who has studied the topic and believes the earth to be less than 10,000 years old. It’s not silly to believe it. It is silly to let someone change your mind with “facts” that aren’t proven true. Remember this: Scientists themselves don’t agree on things! Anytime you hear someone say, “All scientists say that…” you can be sure it isn’t true. It’s propaganda to try and get you to believe something. Don’t be afraid to believe the Bible. It will always prove to be true in the end. God is Truth and cannot lie! You can trust His Word.
