Science Fair Project Idea
thumbnail 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… Read more

Time Required Average (6-10 days)
Prerequisites You'll need a camera with a separate flash attachment to do this project.
Material Availability Readily available
Cost Very Low (under $20)
Safety Be careful in sunlight: the Fresnel lens used in this project can focus enough sunlight to cause burns, melt your flash attachment, or set fires.

thumbnail Digital cameras can be a great way to learn about photography. Most digital cameras today have LCD screens, so you get instant feedback on your photo. If you make a mistake, no problem, you just delete the picture. It's nice that you don't have to worry about the expense and bother of developing film! This project can help you learn to take better pictures. Read more

Time Required Average (6-10 days)
Prerequisites You'll need a digital camera that take pictures in manual mode (a grayscale, or 'black-and-white' mode, is nice to have but not essential). You will need to know how to change the shutter speed, lens aperture, and ISO setting. A tripod for the camera is nice to have, but not absolutely essential. You will also need a computer.

Science Fair Project Idea
thumbnail This is a great project for someone interested in both stargazing and photography. Bright city lights and even the light of the full Moon obscure the dimmest stars, which can make identifying constellations more difficult. In this astronomy science project, you will calibrate a digital camera to measure the skyglow in different locations. This can be a great tool to comparing the quality of different star viewing locations. Read more

Time Required Long (2-4 weeks)
Prerequisites You should have already taken an algebra class and understand what a function is.
Material Availability A digital camera with full manual control is essential for this project. If you cannot manually control the ISO, shutter speed, focus, and lens aperture of your camera, then your camera will not work for this project. See the Materials and Equipment list for details.
Cost Very Low (under $20)
Safety Take an adult with you when you take skyglow photos at night.

thumbnail 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. Read more

Science Fair Project Idea
thumbnail If you were in a raiding army in the Middle Ages, a catapult would come in mighty handy for taking down castle walls. But only if you could aim it reliably! With this science project, you will try your hand at catapult technology. Using a rubber-band-powered catapult you will send ping pong balls flying through the air. The catapult's design makes it easy to measure and repeat how hard the ball is launched and its direction, so you can find the right catapult settings to hit the target reliably. Read more

Science Fair Project Idea
thumbnail In physics class, you have probably rolled your eyes at some point after being assigned a "projectile motion" homework problem where you use equations to predict how a ball will move through the air. This experiment will show you just how fun that problem can be by using a real catapult to launch a ball and videotaping it as it flies along its path. Then, you will analyze the video and compare it to what the equations predicted. If you have ever wondered if those equations in your physics… Read more

- Less Details
Time Required Average (6-10 days)
Prerequisites This project requires a basic understanding of algebra, trigonometry (sine and cosine functions), and physics (kinematics—two-dimensional projectile motion), or the willingness to learn about these subjects on your own.
Material Availability This project requires access to a video camera (not included in the cost estimate) and the purchase of a catapult kit. (See the Materials and Equipment list for details.)
Cost Average ($40 - $80)
Safety Minor injury possible. Never aim the catapult at anyone, and keep your hands and fingers clear of the moving catapult arm when launching the catapult.
Science Fair Project Idea
thumbnail In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

Safety Never launch projectiles at people or animals. Be careful not to get your fingers caught in the moving parts of the catapult.
Science Fair Project Idea
thumbnail If you're like most people, you like listening to music. Have you ever wondered how your ears and your brain turn the sound waves out there in the world into the experience of music in your head? If you're interested in doing a project about how we hear, this is a good one for you. With this project, you'll do background research and make measurements to understand how the sensitivity of your own hearing varies with the pitch of the sound. Read more

Science Fair Project Idea
thumbnail 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… Read more
