Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

Construct batteries that make electricity from fruits with this fun science fair project.

Soil is made up of different layers. How far down do you need to dig to find the soil horizon, or the place where bits of leaves and branches become soil?

What is condensation? Little mad scientists will learn about condensation, states of matter, and air pressure by conducting this cool science experiment.

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!

Discover how to make fake snot with this cool science fair project idea to learn about polymers, enzymes, and more.

In this science fair project, kids measure how weather conditions affect how fast a puddle evaporates.

This fun science fair project idea helps students learn how acid rains are formed and explore how acid rain damages the environment.

Uh-oh! Is that a pill sitting on the counter or a piece of candy?

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

Cleaning can be a chore, but not with this sudsy experiment!

This science fair project investigates why the number of visible stars changes from place to place.

Science fair project that determines whether mass and weight are the same or different.

This science fair idea is a great way for kids to explore static electricity. Kids will give a comb a static charge and watch as it separates pepper from salt.
