Science Fair Project Idea
thumbnail Have you ever noticed how the moon appears bigger at the horizon, just as it is rising over the treetops, than it does later in the evening when it is overhead? Of course, the size of the moon does not change, but our perception of its size changes based on where it is in the sky. In this human biology science fair project, you will investigate Emmert's law, which explains the full moon illusion. You will estimate the size of the perceived increase in the size of the moon at the horizon. Read more

thumbnail 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… Read more

thumbnail Is that right side of your brain yearning to express its artistic side? This is a project that beautifully blends art with science. Learn about light and colorful shadows in these experiments where you mix and match various colors of light to create a mini light show and shadow wall. You might be surprised at the colorful hues you'll find lurking in the shadows. Read more

Science Fair Project Idea
thumbnail You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other colors. Have you ever tried making colors with light? Are the primary colors the same ones you use for paint? Do this experiment and find out. Read more

thumbnail Did you know that sunlight can actually be separated into the colors of the rainbow? And the light of different colors can be added together to make white light or new colors. This is an area of study where art and science overlap. In this science fair project, you will explore this area by drawing or painting "pie slices" onto a white circle and then combining them to make a new color by spinning the wheel using an electric drill.

Science Fair Project Idea
thumbnail In the wild there are two types of animals: the hunters and the hunted. A good predator is always on the prowl for fresh prey. What can an animal do to stay off of the menu? To survive, some animals use camouflage so they can better blend in with their surroundings. In this science project, you will be the hungry predator hunting for M&M® prey. But it may not be as easy as it sounds — some of your prey will be camouflaged by their habitat. Will they be able to avoid your grasp? … Read more

thumbnail Do you know someone who has an autoimmune disease? Autoimmune diseases are fairly common, affecting more than 23.5 million people in the United States, which is about 1 in 13 people! You may have heard of some of them, such as diabetes (type 1), rheumatoid arthritis, and celiac disease. Many autoimmune diseases are poorly understood, but they all have one thing in common: they happen because a person's immune system (which normally fights off germs to keep the person healthy) attacks the… Read more

thumbnail It has been said that, "Life is like a box of chocolates—you never know what you're going to get" (Forrest Gump in Forrest Gump, 1994). In this science project you can test the "Forrest Gump Chaos Theory" by using M&M's®, which are much cheaper than a box of chocolates. What if life is more like a bag of M&M's? Find out in this science project if some things in life are predictable by using the awesome power of statistics. Read more

thumbnail Have you ever heard someone say, "that plant is thirsty" or "give that plant a drink of water"? We know that plants, and even bouquets of cut flowers, need water to survive, but have you ever thought about how the water moves within the plant? In this science project, you will use colored water and carnations to figure out where the water goes. Read more

Science Fair 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.
