In this project children practice the scientific method while playing with puffy paint.

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

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

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.

This simple project makes young children aware of their sense of smell and its capacity for providing them with information about their world.

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 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.

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?

Can you fool your eyes and your brain with an optical illusion? The purpose of this science fair project is to demonstrate various kinds of optical illusions.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

In this science fair project, young children discover what happens when two fluids that have different densities get together.

This is a quick, easy science fair project that conveys the idea of density to preschool and early elementary children.

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

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

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

This project leads to an understanding that a whole may be built of smaller parts that fit and work together and provides an introduction to basic tools.

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

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

In this science fair project, young children will become aware of and have the opportunity to experience the four basic tastes: sweet, sour, salty, and bitter.

Find out whether we can create motion in a dish and as a result, create a wonderful and colorful show.

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

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

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

In this science fair project, kids observe the expansion of liquids when frozen and determine if some liquids expand more than others in the freezing process.

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

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 combining nature, art, math, and science, children make rubbings of leaves then observe shapes and structures and sort the leaf images.

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.

In this science fair project, we'll explore how blocking the sun's light can stop those can stop photosensitive paper from changing color.
