Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.

What's the science behind those out-of-sight roots? Find out if you can trick roots into growing in different directions.

What are the effects of fertilizer on plant growth? What's the best fertilizer type (solid, liquid or powder)? Kids find out in this science fair project idea.

This science fair idea examines hydrogel superabsorbent polymer crystals. They can absorb 500 times their weight in water. Can they absorb other liquids too?

Camouflage is one of the most important animal adaptations in the African savanna biome. Kids create their own camouflage with this fun science fair project.

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?

Check out this fun and easy 4th grade science fair project idea that tests how gravity induces positive and negative geotropism (gravitropism) in bean plants.

What does a raindrop look like when it splashes on the ground? Is each raindrop unique like snowflakes? Find out how raindrop size varies in this experiment.

This science fair project focuses on a polymer called hydrogel super absorbent crystal which absorbs water, swelling to many times its original size.
