Sunless Plant Experiment

Observe how beans behave in the dark compared to those grown in the light by conducting the sunless plant experiment.

Required Materials:

Step 1: Immerse six lima beans in a glass of water overnight for soaking.

Step 2: Take two plastic foam cups and add about 1 inch of small rocks at the bottom of each. Then, add 1 inch of sand to each cup, followed by approximately 4 inches of potting soil in both cups.

Step 3: Plant three bean seeds in each cup. Water them gently to maintain moisture in the soil without overwatering.

Step 4: Place one cup on a sunny windowsill and the other in a dark closet. Observe your beans daily to track their growth. Are the results surprising?

What Happened? After several days, the plants on your windowsill will thrive and be lush. In contrast, the plants in the closet will appear pale, although they may grow taller than the other plants.

Plant cells are equipped with light-sensitive receptors. When exposed to insufficient light, they signal the plant to stretch and elongate in search of a light source.

Because the closet has limited light, the plants do not produce chlorophyll, the green pigment that absorbs sunlight and helps plants make food. If you place the pale plants next to the healthy green ones in the sunlight, over time, they will turn green.

Venus Flytrap Tips

Carnivorous plants are simple and enjoyable to cultivate when placed in the right setting. Just follow these helpful Venus flytrap guidelines!

What You’ll Need:

Step 1: Begin by adding a one-inch layer of crushed charcoal to the bottom of the terrarium.

Step 2: In an old mixing bowl, combine three parts potting soil with one part sand and one part peat moss. Add water until the mixture is damp, but not saturated.

Step 3: Add about three inches of the prepared mixture to the bottom of the terrarium. Then, create a small hole for your plant.

Step 4: Gently remove the Venus flytrap from its pot and place it into the hole you've made. Cover the terrarium afterward.

It's important to keep your plant moist. Most Venus Flytraps die from improper care, as the dry air in your living room isn't suitable. These plants thrive in bogs, requiring humid air and damp soil to stay healthy.

The Venus Flytrap consumes insects to obtain nutrients, since bog soil is low in nutrients. Feed it small insects or tiny pieces of raw meat. Place a piece of meat on one of the leaves and gently tap it to trigger the leaf's closure.

Be mindful that Venus Flytraps are becoming endangered due to over-harvesting, with many being taken illegally.

When purchasing your Venus Flytrap, check the label to determine if it was raised in a greenhouse or harvested from the wild. It’s best to buy plants that have been greenhouse-grown.

The next project in the series 'Science Projects for Kids: Classifying Plants' will uncover the hidden colors in a leaf.

For more exciting science projects and activities, explore these options:

Leaf Chromatography Experiment

Even green leaves hold more colors than you might expect! Discover the concealed rainbows within them through a leaf chromatography experiment.

Here's what you'll need to get started:

Leaves contain a green pigment called chlorophyll, which helps them capture sunlight. But did you know that they also have pigments of other colors to absorb light that chlorophyll can't? Chromatography allows you to reveal these hidden colors in a leaf.

Step 1: Cut a one-inch wide strip from a coffee filter. Shape one end of the strip into a point.

Step 2: Position a leaf on the filter, about 1/4 inch above the cut. Roll a coin's edge over the leaf to transfer the green juice onto the paper.

Step 3: Allow the paper to dry, then repeat the process with three different leaves.

Step 4: Pour a 1/2-inch layer of rubbing alcohol into a jar's bottom.

Step 5: Attach the paper strip to the center of a pencil with tape and suspend it so the very tip of the strip touches the alcohol. Make sure the colored leaf "juices" don't touch the alcohol; you may need to adjust the strip length.

Step 6: Place a piece of foil over the top of the jar to prevent the alcohol from evaporating.

Step 7: Observe closely as the alcohol moves up the paper, carrying the pigments with it. Within 10 to 20 minutes, the colors will separate -- be sure not to let them reach the top of the paper.

How many different colors do you see? Were any of them visible in the leaf itself? The final paper is called a chromatograph. Let it dry and consider using it as a unique bookmark.

Cacti Simulation Experiment

Have you ever wondered how desert plants survive with so little water? Explore their unique characteristics through a cacti simulation experiment.

What You'll Need:

Step 1: Dampen three paper towels so that they are fully saturated with water, but not dripping.

Step 2: Lay one of the paper towels flat on a cookie sheet.

Step 3: Roll up the second paper towel, secure it with a paper clip to keep it rolled, and place it on the cookie sheet alongside the first.

Step 4: Position the third paper towel on a piece of waxed paper that matches its size. Roll both the waxed paper and paper towel together, securing them with a paper clip to hold them in place.

Step 5: Allow all three paper towels to sit undisturbed for 24 hours. After that time, check them. Here’s what you’ll observe:

The flat towel will be dry. The rolled towel will be dry or mostly dry. However, the towel rolled with waxed paper will still be damp.

You might be wondering, "What does this have to do with desert plants?"

Here’s the explanation: Cacti and other desert plants are similar to the paper towel wrapped in waxed paper. These plants have a protective waxy layer that prevents moisture from evaporating into the dry desert air. That’s one of the key reasons they can survive on so little water in such a harsh environment.

Disoriented Sprout Experiment

Seeds have an incredible ability to find their way upwards! Watch them as they strain towards the light in this disoriented sprout experiment.

Here’s what you’ll need:

Step 1: Fill a glass or plastic jar with potting soil, then place a seed along the side of the jar where you can easily observe its growth.

Step 2: Add three more seeds around the jar, ensuring they are positioned so they are visible for observation.

Step 3: Moisten the soil with water, and monitor daily to see if the seeds start to sprout.

Step 4: Once the seeds begin to sprout, cover the jar with black paper. Secure a plastic wrap lid around the jar using a rubber band.

For the next 12 days, adjust the jar's position each day. During this time, check the soil's moisture level every day or two and add water as needed to maintain moisture.

After completing the 12 days of repositioning, remove the black paper. You'll notice that the beans continually adjusted their growth direction to keep growing upward, even though no light indicated which way was up.

Next, in another exciting science activity from science projects for kids: classifying plants, you'll explore how nature can gradually reclaim a field.

For additional fun science projects and activities, visit the following:

Plant Succession Observations

From the growth of weeds to towering trees, observe how nature gradually reclaims the land through plant succession.

What you'll need for this observation experiment:

If you have a lawn, you're familiar with the need for someone to mow it throughout the summer. (Perhaps that's your job!)

Have you ever wondered what would occur if the lawn were left unmowed? Over time, other plants might start to grow amongst the grass.

Soon after, small bushes and shrubs would begin to take root. In wooded areas, trees would eventually start to grow.

This natural progression is known as plant succession. In certain places, you can observe plant succession happening right before your eyes.

Search for land that was once used for farming or grazing but has been abandoned over time.

Once you've identified a piece of land, make sure to observe it at various points during the year to track the changes.

Maintain a journal and document the land's transformation. Over time, nature will take back the area, filling it with native plants, shrubs, and trees.

Get ready to dive into the next plant-related activity in science projects for kids: classifying different types of plants.

For additional fun science projects and activities, explore the following:

Plant Reading and Journaling

The practice of growing plants, known as "horticulture," blends science and art. Dive into plant reading and journaling, and perhaps you'll develop a green thumb of your own.

Here’s what you'll need:

The plant world is vast. Head to the library and grab a book about plants, flowers, or gardening to expand your knowledge.

Put your newfound knowledge to the test. Maybe you'll start your first garden or simply grow a single flower.

Once you're done, write about your experience. Alternatively, create a picture book that illustrates the life cycle of a plant. Don’t forget to add a title and sign it as the author—yourself!

Ecosystem Exploration

An eco-strip is a small section of land that belongs to an ecosystem. Create your own eco-strip and dive into an exciting ecosystem exploration.

What You'll Need:

To create your eco-strip, mark off a portion of land using sticks or large rocks. Pick a natural location like a park, forest, beach, or another outdoor area.

Once your eco-strip is set up, carefully observe every detail. This activity is even more fun with a friend, as you may both spot different things in the environment.

Use field guides to help identify the rocks, plants, and animals in your eco-strip, and jot down your observations in a notebook.

Try to identify as many plants, animals, and rocks in the eco-strip as possible. Look for animal tracks or other signs of wildlife.

Observe how humans may have impacted the eco-strip, whether positively or negatively. Perhaps hikers have left behind trash, or maybe people have placed a water basin for animals during hot weather.

Take thorough notes about all your observations, and create a detailed map of the eco-strip.
