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

Kids will learn how to make a thermometer to to explore liquid density in this great science fair project. Which liquids are affected by temperature the most?

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

Milk is made of water and fat; but how can you separate the two? Find out in this color changing milk experiment.

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.

This simple heat transfer experiment is a great introduction to the concepts of heat transfer and conduction.

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

This science fair project idea investigates if webbed feet help a duck (and others) swim.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

In this experiment you will replicate the mummification process by making a hot dog mummy.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.
