Earth Science Experiments

It’s important to take time to teach young children about the impact that they can have on the world around them. Volusia private schools believe that God has called upon us to act as caretakers of His beautiful creation. Check out these easy experiments that can help get children excited about the Earth and the power they have to preserve it!

Visualize Water Pollution

Getting rid of water pollution isn’t easy. To help children understand how difficult reversing pollution can be, ask them to fill a bucket with clean water. Then, take turns adding household trash and vegetable oil to the water. Ask your children to remove the pollution using tongs and a strainer. They’ll quickly find that no matter how meticulous they are, they’re unable to return the water to its original state.

However, don’t end the experiment on a pessimistic note — this is a wonderful chance to teach them about how we clean water for daily use. Take a trip to a local pond to collect a sample of dirty water in a jar. Back home, help your child grab alum spice, pour it into the jar, and shake it up. Then, let it sit. After a while, you should notice a significant difference in water quality. For extra cleaning, you can place clean gravel into a plastic berry container with holes in the bottom. Pour the water into the container to strain it and further remove dirt.

Create a Rain Cloud

Do you want to teach your kids how rain clouds work? All you need to create your own storm is a clear vase or mason jar filled with water, an eyedropper, shaving cream, blue food coloring, and a mixing bowl. First, squirt the shaving cream on top of your filled glass to create your cloud. In the bowl, mix the food coloring and water— be generous with the amount of color— then use the eyedropper to inject the mixture into the shaving cream cloud. Keep applying the colored water until you see the cloud start to “rain” the excess food coloring into the clear water!

Color-Changing Flowers

Are you looking for a simple, STEM-inspired experiment? You need white flowers, the same amount of vases or mason jars, and food coloring. Fill the vases or jars up with equal amounts of water, and add at least 25 drops of food coloring to each jar. Put one flower into each jar, set them aside, and wait. After a few days, you’ll see the flowers change colors!
