Do you really catch more flies with honey than with vinegar? Do an experiment to find out! Watch the video above to learn how to make a simple homemade fly trap using a plastic bottle. Then, experiment to discover which bait attracts the most flies. You can try a variety of liquids, and you can also use solid bait like rotting food or meat, but you will need to add some water so the flies drown. A drop of soap can help break the surface tension of the water, making it easier for the flies to…

Have you ever seen butterflies fluttering around outside, gliding through the air and landing on flowers? While they are delicate and fragile, butterflies are actually excellent flyers. They are so good, in fact, that scientists at Harvard University studied butterfly wing shapes as an inspiration for building a miniature flying robot. In this science project, you will do your own version of the Harvard scientists' experiment to measure the flight performance of butterfly wings.

Have you ever walked next to your favorite ocean, lake, or creek and seen plastic waste everywhere? Have you ever thought about how much plastic breaks down into microplastics and pollutes waterways? Scientists are coming up with new ways to remove these microplastics from our waterways, and now you can test them out for yourself at home.

Animals survive in all sorts of extreme environments, whether it is a polar bear out and about when it is -40°F, a desert iguana trying to find food as the temperature rises to 110°F, or a deep sea anglerfish living 3281 feet down into the sea. How do they do it? The answer is adaptations! Their bodies have special features that allow them to live in those environments. You might not be able to dive down 3281 feet to observe the deep sea anglerfish, but in this science fair project you…

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…

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.

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…

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…

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…
