Study the life cycle of the common blowfly as it relates to forensic investigation. Record the first time you see flies, maggots, and eggs.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

Help your second grader observe the phases of the moon, and then let the fun loose: he'll get to chart his observations with marshmallows!

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

What animals are most popular? This project affords practice in data-collection, record-keeping and data-analysis through the investigation of this question.

Which music genres have the fastest tempos? The slowest? This experiment determines if there's a relationship between beats per minute in a song and its genre.

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 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.

This project determines what category of person is most likely to be ticklish.

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.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

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

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

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

Find the North Star, and measure your latitude! The purpose of this science fair project is to find latitude and learn about geographic locations.
