What Seeds Do Birds Prefer to Eat?
Science Fair Project Idea
Scientific Method
Are you curious about the birds that live in your neighborhood? Would you like to find out more about them: what they look like close up, what they eat, how they sing? In this project you'll build a bird feeding platform with four separate feeding areas. You'll be able to observe birds at close range, find out what birds inhabit your area, and learn about their seed-eating preferences. So get out your woodworking tools and binoculars, and get ready to see some birds. Read more
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
Can Copper Foil Snails?
Science Fair Project Idea
Scientific Method
If you have a garden, you probably know about snails (or their shell-less relatives, slugs). You may even be looking for a good way to keep them from getting into your garden and eating up the results of all your hard work. In this science project, you will take a scientific look at one method of discouraging this garden pest. 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
Respiration and Gills: What Factors Affect Respiration in an Aquatic Environment?
Science Fair Project Idea
Scientific Method
During metabolism, organisms experience physical and chemical changes. All animals need some way to exchange chemical waste generated during metabolism for fresh nutrients. One way that these metabolic chemicals are exchanged is during respiration, the process by which used carbon dioxide gas is exchanged with fresh oxygen and circulated throughout the body. How do organisms living underwater respirate? They use gills, which filter oxygen from the water and pass the oxygen into the… Read more
What is the Most Effective Treatment for Whitefly Infestations on Plants?
Science Fair Project Idea
Scientific Method
Whiteflies are a group of closely related insect species whose larvae live on plants. Like aphids, they suck nutrients from the plant's circulatory system. What is the most effective method for fighting a whitefly infestation in your garden? This project has some ideas for you to try. Read more
Coffee Buzz: How Does Caffeine Affect the Physiology of Animals?
Science Fair Project Idea
Scientific Method
Caffeine is a type of chemical called a stimulant. When you drink a caffeinated beverage, the caffeine enters into your blood stream dilating the capillaries and causing blood to flow more quickly. This gives your body a feeling of speeding up which can cause the jitters and wakefulness. How does caffeine affect the physiology of other animals? You can use over-the-counter caffeine supplements, like Vivarin, to test the effects of caffeine on animals. Try dissolving the caffeine in… 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
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
