This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

In this project, create and examine garden mulch to find out what critters live in the messy, muddy layers just above the soil.

In this awesome science fair project idea, kids will be attempting to pick up different objects using snail slime.

Using a toy race car kids create a visual model of the Doppler Effect.

This science experiment tests why guacamole goes brown and if leaving the pit in will stop guacamole from turning brown.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

This science fair project teaches students about wilting and browning of salad greens.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

Why do plants wilt? Kids will learn to think critically about what environmental factors affect plants, and what plants need to survive.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

Kids will learn how to clean fish tank the natural way. Add catfish to the tank and see if your water gets cleaner.

Dinosaurs were huge creatures that left behind huge footprints that lasted for millions of years. In this science fair project, kids learn how dinosaur tracks were left behind!

This classic children's game demonstrates how sound travels through air vs. through a solid.

This fun experiment provides a concrete and visually striking illustration of photosynthesis.

In this experiment, students will create their own version of coquina, a sedimentary rock thatâs formed by seashells and sand, cemented by seawater minerals.

Learn how different types of soil affect how animal tracks form in this experiment!

This science fair project introduces children to static electricity and the idea that electricity is more than lights and plugs.

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.

This project makes young children uniquely aware of their sense of touch and its ability to alone give them information about the world around them.

In this project children discover, identify, and sort seeds from a variety of fruits and vegetables

This play-activity causes young children to focus on and become more aware of their sense of hearing and the power of their ears.

In this science fair project, young children notice and track changes in trees throughout the year.

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.
