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

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

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

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

People have favorite flavors, but what about ants? Which ant food is the most popular?

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.

Camouflage is one of the most important animal adaptations in the African savanna biome. Kids create their own camouflage with this fun science fair project.

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

This project examines whether people's taste perception is influenced by what they see.

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

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.

In this science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

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

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.

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 fair project, kids measure how weather conditions affect how fast a puddle evaporates.

This science fair project idea demonstrates how air resistance contributes to denser objects falling faster than less dense objects.

Word color association is just a fancy way to talk about the way we connect colors with words.

What makes your shadow dance around all day? Let's play detective and find out why that sneaky shadow never stays in one place for long.

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

The objective of this science project is to determine the length of time for different seeds to germinate.

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

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

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

The goal of this fun science fair project idea is to microwave candy and investigate: do some colors of M&Ms melt faster than others?

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

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.
