Worm Hunt: Isolating Soil Nematodes from Your Backyard

Science Fair Project Idea

Scientific Method

Do you know what is living in your backyard? How about at the playground, or in your compost pile? Nematodes, also called roundworms, are the most abundant animal on Earth and they might be living in any of these places. In this science project you'll isolate nematodes from several soil samples to discover the best nematode habitats. Read more

Antlion Pits in Open Sand or Under Leaf Cover

Science Fair Project Idea

Scientific Method

Antlion larvae are known for their predatory ways. In sandy areas, they dig pits to trap ants or other crawling insects that happen to stumble in. This project shows you how to create a mini-environment for antlion larvae to test their preferences for pit-building sites. Read more

Attractants and Repellants

Science Fair Project Idea

Scientific Method

Animals respond to chemical cues in different ways. If an animal turns away from a chemical cue, then that chemical is a repellent. If an animal turns toward a chemical cue, then that chemical is an attractant. Attractants and repellents can be airborne chemicals, chemicals found in food, or chemicals that diffuse through water. One example of an airborne chemical is a pheromone, a chemical signal that is released by one individual to attract another. Moths release pheromones to attract… Read more

Have you ever wondered how animals can survive in all sorts of extreme environments, from a polar bear that’s out and about when it’s -40°F and a desert iguana finding food as the temperature rises to 110°F, to a deep sea anglerfish living thousands of feet down in the sea? How do they do it? The answer is adaptations! Their bodies have special features that allow them to live in those environments. In this activity, you’ll investigate what the… Read more

Day or Night?

Science Fair Project Idea

Scientific Method

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

Do Migratory Birds Like It Hot?

Science Fair Project Idea

Scientific Method

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

Does Body Size Matter?

Science Fair Project Idea

Scientific Method

Animals come in all shapes and sizes, even humans. You can look up different statistics about different kinds of animals using the Internet: average body size, brain size, life expectancy and generation time are some examples. Is there a correlation between body size and life span? Is there a correlation between body size and brain size? Is there a correlation between body size and generation time? Is there a correlation between body size and the size of your footprint? (Comparative Mammalian… 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

How Much Worm Is a Worm?

Science Fair Project Idea

Scientific Method

Worms are slimy, wiggly, and gross. But did you know that they have many unique abilities? One of the neatest things that worms can do is regenerate, or re-grow, parts of their body. After a piece of a worm is cut off, it can grow back with all of the necessary new parts. How much of a worm can you cut off and still get regeneration? Is one end of the worm better at regenerating than the other? See if you can make heads or tails of this wiggly problem! Read more
