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
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
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
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
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
Eggs and Hen's Diet: Can You Get Bigger Eggs for Peanuts?
Science Fair Project Idea
Scientific Method
If you keep chickens (lucky you!), here's an interesting project you might want to try. 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
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
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
