Others Like “How Does Color Affect Heating by Absorption of Light?”

Science Fair Project Idea
Everyone has experienced the warmth provided by a shaft of sunlight through a window. In this physics science fair project, you will determine how the color of an object affects the amount of radiant energy that is absorbed. You will then use the Stefan-Boltzmann equation to determine the amount of energy that is absorbed and re-emitted by the different colors. Read more

Science Fair Project Idea
thumbnail Have you ever wondered what it would be like to have an extra sense? What if you could hear above the normal range (ultrasound) like dogs or bats? What if you could see ultraviolet light, like bees or juvenile trout? What if you could see infrared light, like a rattlesnake or boa constrictor? This project shows you how you can use a camera, tripod and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world. Read more

Science Fair Project Idea
thumbnail We encounter an amazing array of colors every day, from the greens of plants and the many colors of their flowers, to the pinkish blue of a sunset, to the artificial coloring in beverages. How do we perceive all of these colors? When light hits an object, some of that light is absorbed by the object, and the light that is not absorbed is what we see. In this science project, you will build a simple spectrophotometer from a cell phone and use it to investigate how visible light is absorbed by… Read more

Science Fair Project Idea
thumbnail What's your favorite thing to do on the hottest day of the year? Dip your toes in an icy river? Hang out by the pool? Retreat to a cool basement? Lie motionless in the shade? You're probably not too eager to move around and put out a lot of energy, like mowing the lawn in the mid-afternoon sun. Well, you're not the only one. In this electronics science fair project, you'll find out that some semiconductor devices, like light-emitting diodes (or LEDs), act the same way. As their internal… Read more

Science Fair Project Idea
thumbnail Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Engineers are hard at work on the James Webb Space Telescope, or JWST. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to. However, to make the telescope work properly, engineers have to overcome a lot of challenges. In this science project, you can… Read more

Science Fair Project Idea
thumbnail What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more

thumbnail Would you like some sky vegetables for dinner? How about some fresh-cut roof flowers to put in vases in your house? Around the world, rooftops are being transformed into living green expanses. Besides beauty, rooftop gardens have a number of advantages, including growing food and taking carbon dioxide out of the air while releasing breathable oxygen. But can rooftop gardens also keep your house cooler and lower your energy bill? Try this science fair project to find out. Read more

Science Fair Project Idea
thumbnail Light interacts with matter in a variety of ways—it can be absorbed, reflected, refracted (bent), and scattered. The scattering of light explains why the sky is blue, why milk is white, and why the Mississippi River is called "The Big Muddy." In this biochemistry science fair project, you will make an electronic device to measure the amount of scattered light in milk. You will also use the device to track the activity of protease (a type of enzyme) in pineapple juice, based on its ability… Read more
