Young scientists will investigate people's preferences for saltiness, and make some inferences about genetics and diet.

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.

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

What causes dilated pupils? Young scientists will find out by applying what they already know about changes in pupil size and making models of the pupil.

In this experiment, young ecologists will learn about a type of edge effect: how trees and plants at the edge of a forest can act as a weed filter.

Magnets vary in strength. Have your young scientist figure out which kind of magnet is the strongest when you have him conduct this attractive experiment.

Can a toy car determine the strength of a magnet? In this cool magnet science fair project, young scientists will learn how to measure the strength of a magnet.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

This science project encourages students to investigate the Mozart Effect, the idea that classical music promotes learning.

This science project allows students to study the psychology of happiness.

Do lefties just write different or are their brains different? This science project has students explore what it means to be left handed.

This science fair project teaches kids experimental design and how to test if subjects can really sense if they are being watched.

This science project has students study a group of volunteer liars actively lying to study the behavior of a lie. Students see if they can figure out the truth.

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

This science fair project compares the allelopathic affects of juglone, a chemical agent produced by the Black Walnut tree, on two plants.

Ant behavior is closely related to light intensity. This free science fair project idea examines how fast ants dig when they are exposed to to light and dark.

The objective this science fair project is to determine whether a bigger bag will allow a homemade hot air balloon to fly higher than smaller bag.

This science fair project idea determines if crystals will absorb food dye and if colors will mix by the process of diffusion.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot move in a pattern related to the sound and rhythm of music.

In this activity, students will think about the form and function of household objects as they compare and contrast kitchen serving spoons of various sizes and designs.

Throughout history, people have used song as a teaching and memory tool. This project explores whether song improves a person's ability to retain information.

In this open-ended activity, students will be given a small quantity of three types of materials and asked to design a prototype for “something that will improve the school.”

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.
