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

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

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

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

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

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

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

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

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

In this science project, young children observe, record, and create collections of colors in their world and increase their powers of observation.

This engaging project encourages young children to practice and refine the important scientific skills of sorting and classification.

In this science fair project, young children observe, record, and create collections of shapes in their world and increase their powers of observation.

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

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.

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.

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

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.

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 introduces children to static electricity and the idea that electricity is more than lights and plugs.

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

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

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

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

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

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 science fair project, students learn how pressure can make the minerals in a rock line up in the same direction and form bands and foliation.
