Imagine you are on a trip and see something interesting that you want to share with your friends. What do you do? You take a picture with your cell phone and e-mail it to them, of course. But did you realize that the same technology can be used to save lives? Using their cell phones modified as inexpensive microscopes, medical personnel can look at blood smears to help diagnose diseases like malaria and cholera. In this photography science project you will build a simple and inexpensive cell…
Pinhole cameras are not just for grannies! Even compared to all of the latest technology, a pinhole camera still gets beautiful results. Find out how this very simple aperture design works to control the way light enters the lens of your camera.
If the prefix "macro" means large and "micro" means small, then why will the macro setting of a digital camera help take a better picture of a small object? Do this experiment and get the big picture.

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 phone or camera, tripod, and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world.
If you sit under a leafy tree on a sunny day, you may notice spots of sunlight on the ground from light passing through spaces between the leaves. Try putting a piece of cardboard on the ground and examining the spots of light on the cardboard. Even though the spaces through which the light is passing are irregular in shape, the spots on the cardboard are round. What you are seeing, in fact, are projected images of the sun. Light passing through an aperture forms an image. A pinhole camera…
Here's an interesting flash photography project. With an inexpensive Fresnel lens, you can concentrate the light from your flash. You'll be able to shoot with a smaller aperture and a shorter flash duration. This will give you greater depth of focus and will allow you to 'freeze' motion at higher speeds. The trade-off is that the light will be concentrated toward the center of the frame. This project shows you how you can investigate that trade-off and find out how you can best use your flash…
Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many naturally occurring molecules have this property, called chirality. Chiral molecules can interact with polarized light in an interesting way—they rotate the plane of polarization. This chemistry science fair project describes how to make a homemade polarimeter…
In this project you'll learn about how digital image files are encoded, and how digital images can be compressed so that the files take up less storage space and can be transmitted more quickly. You will also measure the quality of compressed and uncompressed images, which will give you important insights into the tradeoffs between file size and image quality.

Have you ever seen a skateboarder jump over an obstacle or slide down a railing? It looks like they are defying the laws of physics when they perform these tricks. It looks like it, but that's not the case. Physics describes the motion of objects and it is a skateboarder's best friend! All of these tricks can be explained by physics. In this sports science fair project, you will learn how speed affects "popping an ollie." The ollie is a basic skateboarding trick, and it's the first step to more…

Have you ever taken notes from the chalkboard during class and not noticed what was going on around you? Or have you ever been so focused on a task that you haven't seen other people around you? In both of these cases, you were paying attention, but you were seeing without seeing! This is called inattentional blindness and it's the topic that you will investigate in this human behavior science fair project. If you are interested in how the human brains perceives information, then this might…
