This experiment researches if you gave different amounts of food to mosquito larvae would they grow faster or slower

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!

How do animals keep warm? In this experiment, find out whether fat insulation resists cold temperatures and learn how this works in the animal kingdom.

Why do plants wilt? Kids will learn to think critically about what environmental factors affect plants, and what plants need to survive.

Do you think heat can affect a plant's growth rate?

This flannel board will give your child hands-on practice with math, but in a fun format, full of ladybugs.

This science fair project teaches you about what makes persimmons so tart and how astringency can be removed by studying the effect of tannins on fruit.

When you rub a balloon on your head, your hair stands up; but is that true for everyone? Does hair color affect static electricity?
