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!

Learn about the layers of the Earth and make a model! Create a earth layer book, cake, or clay diagram.

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

What causes the seasons to change? Kids find out by modeling the earth's tilt using a globe, flashlight and graph paper in this cool science fair project idea.

How well can people recall what they have observed. Test your knowledge in this fun experiment.
