Science fair project that uses muriatic acid to develop fingerprints that would otherwise be invisible.

In this project students experiment with making music using only glasses of water.

Why does purple cheese look nasty? Because color plays a big part in how we perceive the taste of different foods. Are birds just like us in this respect?

How do organic materials become soil? This science experiment measures what materials biodegrade.

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

Tired of gum with flavor that lasts for just a couple of minute? Put gum to the test with this chewy science experiment!

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 objective of this science fair project is to study the photosynthesis process and demonstrate the important role that leaves play in the process.

The objective of this science fair project is to examine the basic principles of air pressure using simple materials like a balloon, straw and string.

Have you ever noticed the way a dropped stone makes a fun pattern in a pond or lake? What's the science behind these splashy occurrences?

In this science and engineering activity, children will explore types of tunnels and their purposes and then design and build a tunnel of their own.
