Do Milkweed Bugs Show a Color Preference for Egg-Laying Sites?
Science Fair Project Idea
Scientific Method
Milkweed bugs, as their name suggests, have a close relationship with the milkweed plant. The plant produces an irritating, milky sap, and toxic compounds, but somehow the milkweed bug is unaffected by them. Instead, it concentrates chemicals from the sap in its body, acquiring an unsavory taste that, along with its bright coloration, protects it from predators. Given this close relationship, will the milkweed bug exhibit a color preference for egg-laying sites? This project is designed to find… Read more
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
With a Little Bread as Bait, Can You Make a Bird Migrate?
Science Fair Project Idea
Scientific Method
You might like to play in the autumn leaves and winter snow, but have you noticed that many birds don't like to stick around for the cold weather? And instead of the birds you're used to seeing in the warm months, your new feathered friends might be Canada geese. Why is that? Various types of birds and other animals travel from one place to another either in search of food, warmer temperatures, or other things they need to survive. This type of traveling is called migration. Try starting your… 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
Where Do Lizards Go for Lunch?
Science Fair Project Idea
Scientific Method
You've probably heard about differences between the left brain and the right brain in people. Did you ever wonder where that came from? Do other animals have specialized brain hemispheres too? One hypothesis has it that brain lateralization evolved as a survival mechanism in animals with eyes on the sides of their heads. One eye could focus on finding food, while the other watched out for predators. This project tests that hypothesis by looking for left-right bias in feeding behavior in lizards. Read more
Skeleton Building
Science Fair Project Idea
Scientific Method
Do you like skeletons? One of the more interesting jobs at a natural history museum is the creation and care of the skeletons and bones. How do the curators clean and put together the skeletons? Many curators use the carrion beetle, Dermestes vulpinus, to quickly clean off the dead animal tissue from a corpse to reveal the skeleton. These insects do such a good job that sometimes the skeleton remains intact! Another method is to slow cook the carcass until the meat falls off. You can use… Read more
The Touch Response
Science Fair Project Idea
Scientific Method
All animals need to respond to changes in their immediate environment. The sensory structures of animals are each made to respond to distinct types of sensory stimuli: touch, taste, sound, light and smell. How are these stimuli received? Different animals have different strategies for receiving stimuli and develop specialized structures for doing so. Antennae, ears, noses, tongues, eyes, eye spots, hairs and bristles are all examples of sensory structures used by different animals to sense… 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
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
