Project Idea
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

Project Idea
Many organisms have ways of orienting toward or away from an environmental stimulus. Some of these behaviors are instinctive, meaning they are behaviors with built in instructions that do not need to be learned. The instinctive response to a stimulus is called a taxis, and there are several types of cues: electricity (galvanotaxis), gravity (geotaxis), light (phototaxis), heat (thermotaxis), touch (thigmotaxis) or a chemical (chemotaxis). You can design experiments to test whether organisms… Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability This science project can be done with insects you catch in your own backyard or order from [# ProjectGuide Name="Advanced.ApprovedSuppliers" Value="HtmlAnchor" HtmlText="online vendors" #] such as [# Link Name="Advanced.ApprovedSuppliers.2" Value="HtmlAnchor" HtmlText="Carolina Biological Supply Company" #]
Cost Very Low (under $20)
Safety If you choose to try this science project with small animals (rather than with insects), use caution when handling the animals and always have an adult present. The use of small animals may require [# ProjectGuide Name="Advanced.ScientificReviewCommitteeSRC" Value="HtmlAnchor" HtmlText="SRC approval" #].

thumbnail This project shows that our perceptions can change, even with the stimulus remains the same. A clear color difference in an image disappears after just 20 seconds of looking at another (special) image. Now you see it, now you don't! Read more

Project Idea
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

Project Idea
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

Safety If you choose to try trapping small animals, adult assistance will be necessary. Avoid touching wild animals. Seek immediate medical attention if bit by an animal.
Project Idea
thumbnail You have probably heard about left-brain and right-brain differences in people. The left brain is supposed to be better at language, and organizing sequential actions, the right brain is supposed to be better at visualizing orientations in space, making and listening to music, and deciphering the emotions of others. Is there evidence for left/right brain specialization in other animals? This project examines tail-wagging in dogs. Does tail-wagging show any evidence of left/right brain… Read more

Time Required Very Long (1+ months)
Prerequisites You must be comfortable working with dogs. You'll need a video camera, a tripod, a dog crate, and at least 10 different dogs to participate in the project.

Cost Average ($50 - $100)
Safety Adult supervision required.
Project Idea
thumbnail When someone yells, "Think fast!" and throws you a ball, are you able to catch it? When the bell rings at the end of class, are you the first one out of your seat? Can you make it through a sudden hairpin turn in a video game without crashing? If so, then you likely have quick reaction times. In this science fair project, you'll look at reaction times (how fast people react to sensory events), and see if people who play video games have faster reaction times than those who do not.

thumbnail Did you know that some teachers give their students a peppermint candy on state testing days? Is it to give the kids sweet-smelling breath? Or are the teachers hoping for something more on the important testing day? In this human biology science fair project, you'll explore whether or not peppermint influences scores on different types of tests. Read more

Project Idea
thumbnail We tend to think of plants as immobile, but the tendrils of a vine, such as the morning glory, actually move in response to touch. Tendrils wrap around structures, which give the plant something to grow on. In this science fair project, you will investigate how plant tendrils respond to touch stimuli. Read more

Time Required Very Long (1+ months)
Prerequisites This science fair project requires healthy growing plants with tendrils. It may take 3 to 4 weeks to grow the plants from seeds.
Material Availability Specialty items: A growing plant with tendrils, such as a morning glory or sweet pea.
Cost Low ($20 - $50)
Safety Use caution when using the razor blade or craft knife. Adult supervision is recommended.
Project Idea
Our metabolism changes as we get older, a sad fact of life that we cannot change. Old age affects our bodies in many ways. Changes in musculature, bone strength, energy, diet and breathing are some of the many ways we change as we age. You might notice that people often get out of breath when they are older and doing a physical activity. Why do some people feel out of breath, while others do not? Does this change correlate with age? Could this reflect a difference in lung capacity between… Read more
