Kids will learn how to make a thermometer to to explore liquid density in this great science fair project. Which liquids are affected by temperature the most?

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

Why doesn't the ocean freeze? Students answer this question by simulating the chemical composition and temperature of arctic waters in their own home.

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!

This pumpkin dessert recipe tastes like pie but looks like a no-bake cookie.

Invite your second grader to help you measure and mix these fresh, cool concoctions!

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.
