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

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

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

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.

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

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.

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

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

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

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

Here's a science activity to help your child investigate how seeds are designed to travel.
