Protozoa and ciliate and amoeba, oh my! The objective of this science fair project is for students to use a microscope and identify microscopic life.

This science fair project idea attempts to train a worm to complete a simple maze in order to find out if worms can learn and remember.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

This science fair project idea explores whether cats can be trained in the same way that dogs can.

This project uses science and art to help students learn and teach others about Earth's endangered and extinct species.

What is biodiversity? Kids will study different areas of their backyards to see which is the most diverse to learn about biodiversity and random sampling.

In this plant habitats activity, children play the role of an ecologist and take surveys of different areas to discover the best habitat for dandelions.

This science experiment tests if dog saliva can really help heal wounds.

Some fossils have been been preserved for billions of years! Help your kid understand how fossils are created and preserved with this crafty project.

In this activity, your child will make her own "quicksand" to better understand how a substance can be both fluid and solid at the same time.
