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

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

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

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

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

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

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

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

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