Dinosaurs were huge creatures that left behind huge footprints that lasted for millions of years. In this science fair project, kids learn how dinosaur tracks were left behind!

In this awesome science fair project idea, kids will be attempting to pick up different objects using snail slime.

Learn how different types of soil affect how animal tracks form in this experiment!

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

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?
