Now You See It, Now You Don't! Test Your Peripheral Vision
Peripheral vision is important in our everyday lives because it allows us to gather a visual sense of our surroundings—without it, we would see the world through "tunnel vision." The survival of our ancient ancestors depended on their ability to use peripheral vision to find prey and to avoid predators. Almost everything we do—from riding a bike, to dribbling a basketball, to reading a book—depends on peripheral vision. In this human biology science fair project, you will test the limits of peripheral vision and learn how to understand your results based on the anatomy of the human eye.

Minding your Mummies: The Science of Mummification
Have you ever seen or heard of the movies
The Mummy or
The Mummy Returns? Mummies have always played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual. They believed that preserving human remains was necessary so that the previous owner could enjoy the fruits of the afterlife. In this science fair project, you will learn about the rituals and science of mummification by mummifying a hot dog.

Pinocchio's Arm: A Lie Detector Test
Have you ever watched a great sports player and imitated his or her moves over and over again? Or have you ever felt really bad when someone got hurt or things just weren't going his or her way? If so, you might be surprised to learn that you have been practicing skills closely tied to lying! In this science fair project, you'll discover how your brain gets a workout when it moves from truth-telling to lying, and how you can detect the shift. That's no lie!

Are Your Eyes Playing Tricks on You? Discover the Science Behind Afterimages!
Yogi Berra said "You can observe a lot by just watching." In this human biology science fair project, you will observe how your eyes perceive color by watching afterimages. Afterimages are the images you see after staring at an object for several seconds and then looking away. You will also learn how different cone cells in your retina respond to different colors.

You Are What You Eat!
Thinking about improving your sports performance? Want to help friends and family make the most of their physical fitness activities? One factor to consider is food! Whether you realize it or not, what you eat
does change your body! It affects how you feel, and can even change how you perform in sports. This science fair project will help you explore the link between what goes in your mouth and what your legs and arms can do.

Think Fast: Do Video Game Players Have Faster Reaction Times Than Non-Players?
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.

Old Salty: Does Age Affect the Ability to Detect Salt?
Sauerkraut, pickled fish, pickled vegetables, kimchi, corned beef, processed cheeses, smoked lunch meats. Do you like these high-salt foods? What about your grandparents, do they? Do your grandparents seem to like most foods to be a bit saltier than you do? Try this science fair project if you want to find out more about the incredible, edible rock known as salt, and why people vary in how much of it they like to eat.

The Nose Knows Smell but How About Taste?
Ahchoo! Got that stuffy nose and I-can't-breathe kind of cold? Those sniffles and clogged sinuses are bad enough, but why does it also seem everything tastes so bland and flavorless when we are sick? Is there really truth to the idea that smell is a key part of taste? Gather up a few volunteers, hit the kitchen, and try this experiment to find out.

Can Your Body Temperature Tell the Time of Day? Find Out with Human Circadian Cycles.
Have you ever had to adjust to a new time zone and noticed that it takes a while before you start to feel normal again? By shifting your sleep and activity schedule, you have altered the pattern of your body’s circadian rhythms. Human beings, like many other living things, have a number of internal processes that show a distinct circadian rhythm. The most obvious is our sleep cycle, with activity during the day, followed by sleep during the night. Circadian rhythms have also been demonstrated in humans for changes in body temperature, heart rate, alertness, and physical performance in sports. In this human biology science fair project, you will investigate human circadian rhythms by measuring body temperature and reaction time at different times of day.

Lung Capacity and Age
*
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...
