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…

Playing sports can be a lot of fun, but some sports pose higher risks of concussions, or brain injuries resulting from collisions, especially in contact sports like football. Some coaches, teams, and players use new warning devices mounted on helmets that sound an alarm after the head receives a serious impact. This gives an advanced warning of concussion risk (possibly before any of the medical symptoms might appear), signaling that the player should stop playing and see a medical…

How much air do you think you breathe in when you take a deep breath? Can you increase your lung capacity by exercising regularly? Do athletes have greater lung capacity than non-athletes? This project shows you how you can find out.

Do you have bats in your neighborhood? Have you heard them "whoosh" by you, but not been able to see them? In this science fair project, you will be able to detect flying bats by listening in on the ultrasonic signals they produce to locate objects in their environment. The bat detector is a useful and fun tool for studying the biology of this nocturnal flying mammal.

What happens to the food leftovers in your home? Do they go in the trash? Down the garbage disposal? Or get gobbled up by the family dog? Food leftovers are a type of organic waste, a waste that comes from a plant or animal. Organic waste—like table scraps, agricultural waste, and human and animal waste—is biodegradable. This means, it can be chemically broken down by bacteria, fungi, or other living organisms into very small parts.
Figure 1. This…

Have you ever seen a great movie and then rushed out and bought its soundtrack? Did the soundtrack bring back the thrill of an action chase? Or the sadness one of the movie's characters felt? Music is a big part of the movie experience. It intensifies the emotions in scenes so that you do not just jump when that hairy spider comes around the corner, you scream! In this music science fair project, you will find out if happy, sad, scary, and action scenes in movies use music with the same…

Do you enjoy watching cartoons and animated movies? Do you have fun playing video games? What do all of these things have in common? Fantastic computer animation, that's what! It's a cool job to take an interesting story or game and make it more entertaining by animating it. In this computer science project, you won't animate a full-length feature movie, but you will animate a pinwheel—a project that can go a long way toward creating your own longer animations! You will create an animated…

If you'd rate yourself high on the bacteriophobia scale, just keep on scrolling down to the next project. Bacteria are all around us, and normally our body's defenses keep us blissfully unaware of them. If you don't mind finding out where they're lurking in your house, then you might find this project interesting.

Can an authority figure make someone question their own memory? How reliable is eyewitness information? This project looks into these questions. You'll need a poster-sized image that includes many faces, and a volunteers to act as "eyewitnesses." The volunteers are tested individually. The instructions are that they have one minute to examine the poster, and then a fixed amount of time (e.g., 5 minutes) to write down brief, accurate descriptions of all the faces they can remember. They'll…

Do you ever use a password to log in to a computer, email account, or website? Do you use the same password for each one? Even if your password is very long or hard to guess, using the same password for many accounts can still be risky. If someone manages to find out your password (for example, via a phishing attack, or if you write your passwords down and someone finds the piece of paper), they could easily access many of your accounts. However, memorizing lots of different passwords can be…
