This science fair project looks one of the most important factors affecting seed germination: water. A fun and easy plant biology experiment for 3rd graders.

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

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 project determines whether Styrofoam, paper, or plastic cups are best for preventing ice from melting.

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

Get estimating with this spooky activity that asks your young mathematician to rely on their problem-solving skills to figure out how many items they believe are in spooky Halloween jars!
