This fun science fair project idea explains what a circadian rhythm is and explores the types of biological activities that follow a 24 hour cycle in mammals.

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

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

A project to reinforce learning about the layers of the rainforest, rain forest ecosystem, and the greenhouse effect.

Can a horse lead itself to the carrot? Train your horse with carrots and boxes and test horse memory in this fun zoology science fair project.

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

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!

This science fair project idea compares biodiversity between drops of water.

Test whether cutting up meats will make it cook faster than just cooking it whole.

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.

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

This science fair project idea determines what factors influence an individual's reaction time using a web-based timed reaction test.

In this experiment, young ecologists will learn about a type of edge effect: how trees and plants at the edge of a forest can act as a weed filter.

This experiment will explore if magnetism has any effect on the regeneration abilities of flatworms.

Science fair project that identifies the differences between soils from different environments and attempts to figure out why those differences exist.

This science fair project idea investigates food preference of birds.

Research historic methods of food preservation. Analyze alternative recipes and techniques of food preservation. Document success with photographs.
