Science fair project that examines the different types of precipitation, evaluates the density of snow and calculates the ratio of snow-to-liquid.

Get your hands on a concoction that breaks the rules about what's a solid and what's a liquid.

What's a liquid? What's a solid? What better way to experiment than by turning a childhood favorite, ice cream, into a homemade science lesson!

Teach children how to upcycle dried-out markers with this homemade paint-making activity!

This science fair project idea examines whether adding gelatin causes a solid to have a higher melting point and/or melt slower.

Kids will conduct a cool limewater carbon dioxide test that can be performed with common household materials to learn about the chemistry of this common gas.

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

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!

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.

This science fair project idea teaches how the gases and pollution in the air affect the earth's atmosphere temperature.

Young scientists develop a hypothesis, conduct an experiment, and then revise their hypothesis to find out which common household liquids dissolve candy corn.

In this 3rd grade science activity, you'll experiment with the little-known fourth state of matter: polymers! Mix borax with white glue and watch what happens.

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.
