Science Fair Project Idea
Have you ever stopped to watch a trail of ants moving back and forth between a food source and their nest? Have you ever wondered how they establish their trail? You've probably read that ants use chemical signals to communicate with one another. This is a relatively simple experiment that you can do to determine whether ants use attractant signals (positive cues) or repellant signals (negative cues) or both. Read more

Science Fair Project Idea
If you had to choose between having your favorite dessert, going to a movie, or spending the night at a friend's house, which would you choose? This science project shows you how you can "ask" a sowbug (or pillbug) a similar question in order to learn about their preferences. Give it a try to find out what types of microenvironments these tiny crustaceans prefer. Read more

Science Fair Project Idea
How do you figure out how to get places? Do you ask for directions, look at a map, or consult a compass? There are many ways for people to figure out how to travel from one place to another, but how do other animals do it? In this science fair project, you'll use real data, collected by biologists, to figure out how migratory birds manage to navigate more than 2,000 miles from their breeding grounds to their wintering grounds.

Science Fair Project Idea
Animals have different levels of activity depending upon their habitat, metabolism and behavior. Diurnal animals are more active during the day. Nocturnal animals are more active at night. Being diurnal or nocturnal may have different advantages for different animals. For example, desert animals tend to be nocturnal so they can stay cool and escape the desert heat present during the day. What types of diurnal and nocturnal animals are common in your area? You can set out a small trap to… Read more

Why do birds migrate? Do all birds have the same reasons for migrating? Where do they go when they migrate? These are questions scientists have asked for centuries. The more species for which they gather data, the more specific the answers become. In this science project, you will choose a species to investigate, then access and evaluate real data collected by scientists to start answering those questions yourself! Read more

Science Fair Project Idea
Have you ever wondered how many different types of animals live around your home, like in your backyard or a local park? Animals come in all shapes and sizes, each a small part of the amazing diversity of life. These differences can also help us to classify animals into different groups. One way people classify animals is by their phylum. Do you know which phylum you belong to? In this science project, you will investigate the diversity of the animal life around your home and try to figure out… Read more
