A math project teaches students to use a clinometer to gauge the height of very tall objects like trees & to think of better ways to measure how high they are.

Young physicists learn about apparent weightlessnessâthat weird sensation you sometimes feel in elevators, turbulent airplanes, and roller coasters.

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

This science fair project idea determines how quickly germs and bacteria spread.

This science fair project idea's objective is to become familiar with items your family regularly throws in the trash.

Measure the speed of the earth's rotation using protractors and meter sticks. This science fair project measures the angle of the sun in relation to earth.

This science fair project idea recreates the movement of planetary bodies in order to learn why they sometimes appear to move backwards.

Get a cool middle school chemistry project idea on how to determine whether a physical or a chemical change has taken place.

Build a magnetic linear accelerator using a ruler, neodymium magnets, and small metal balls in this fun science fair project exploring magnetic propulsion.

Learn how milk freezes into ice cream. Does the fat content affect how quickly the milk freezes? What is salt's role in the freezing process?

Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.

Saturn is the ringed planet in our solar system, a gas giant with rings made of ice and dust. Let's make a cool scale model with an old CD and some glitter!

The apparent movement of the sun has been used to keep time since the bronze age. In this science fair project, kids plot solar time against mean solar time.

The objective of this science experiment is to evaluate the affects of high and low heat capacity on a material's heat retention ability.
