This science fair project idea investigates whether rocks containing geodes can be determined from the outside.

This science fair project idea studies which kind of rock (sedimentary, igneous, or metamorphic) is most damaged by frozen water.

Collect 26 rocks and paint each one with a letter of the alphabet for your very own alphabet rock collection.

Determine which kind of rock (igneous, sedimentary, metamorphic) has the greatest reservoir capacity, which is the ability to hold the most oil and natural gas.

Did you even wonder why some rocks are round and smooth while others are broken up into small pieces?

Is your little scientist up for a rocky challenge? Let them make their own geode rocks using eggs and epsom salts!

This free science fair project explores the "dirty" relationship between the presence of organic material in soil and water absorbency.

In this experiment, students will discover how heat and pressure turn clay into slate, phyllite, and finally schist.

Wiggly worms are known for staying buried in the soil, but how does that affect plants? Are earthworms and plant growth related?
