Do Magnets Affect Regeneration in Planaria?
Science Fair Project Idea
Scientific Method
The human body has an impressive ability to heal itself after injury, but humans have nothing on planaria. Planaria have an amazing ability to regenerate. An entire animal can regenerate from just a fraction of the body! This project investigates the effect of magnetic field intensity on planarian regeneration. Read more
Drawing Circles Around Ants
Science Fair Project Idea
Scientific Method
Do ants sometimes ruin your picnic? There are some chemical ant repellents you can spray to keep them away, but who wants to spray poison all over their food? In this science project you can investigate some less toxic solutions that may be around your home so that your next picnic will not become an ant buffet! Read more

It might seem impossible to estimate how many different bugs live in a nearby field, or how many types of birds live in a forest, but wildlife biologists often have to try to determine the number of different species in a given habitat. This plays an important role in helping us understand how healthy the environment is. In this activity, you will get to take on the role of a wildlife biologist by examining the biodiversity of bugs and other small invertebrates (such as spiders, centipedes,… Read more
Go and Stop? Ant Traffic Signals
Science Fair Project Idea
Scientific Method
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

Do you love to hear the pulsing chirp of crickets as you fall asleep? It is an unmistakable sound. Some people find the sound pleasing and peaceful, but other people find the sound loud and annoying, especially if a cricket happens to get inside a home to escape the cold. However you feel about crickets, their chirps hold a surprising message — they can be used to predict the temperature! In this science activity, you will investigate how the chirps of these tiny creatures can be used… Read more

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 help people use systems 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 activity, you will investigate the diversity (or biodiversity) of the animal life around… Read more

Have you ever wondered how an unborn chick breathes inside its shell? Every animal needs oxygen to live, so the chick must get air somehow! When an animal—including a human—inhales, oxygen enters its lungs and is then distributed to all the different parts of its body. The animal's metabolism converts the oxygen into energy. During this process, a waste gas called carbon dioxide is produced. To get rid of it, the carbon dioxide is carried back to the lungs, where it is collected… Read more

Ladybug Spots and Breeding
Science Fair Project Idea
Scientific Method
Ladybugs are common insects in North American gardens that prey upon aphids, making them all the rage in biological pest control. Ladybugs can be bred in captivity making them a good insect to study. Just chop off an aphid infested plant stem for food, make a water soaked cotton ball for water, and add to a small plastic container with a lid to make a breeding box. You can use ladybugs collected from the wild, or buy ladybugs from your local nursery. The most common species is the 12-spotted… Read more
Squirmy Wormy: Which Soil Type Do Earthworms Like Best?
