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

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.

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

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.

Get a better understanding of water content by dehydrating carrots.

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.

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

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

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

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.

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.

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!
