Picture This: Building a Cell Phone Microscope
Science Fair Project Idea
Scientific Method
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… Read more
Camera Lens Testing
Science Fair Project Idea
Scientific Method
Do you ever use the manual camera settings when taking pictures with your phone? Does your phone have more than one camera lens? This project is a great way to learn more about your phone's camera(s) and how to take better pictures. You can also do this project with a traditional point-and-shoot camera or another camera like a DSLR. Read more
Camera 'Shakes'
Science Fair Project Idea
Scientific Method
You can compare the picture quality for photos taken at different shutter speeds with the camera handheld vs. with the camera on a tripod. (This is best done with a camera that has manual exposure control.) Read more
Digital Pinhole Camera
Science Fair Project Idea
Scientific Method
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
Smarter Farming with Aerial Photo Analysis
Science Fair Project Idea
Scientific Method
Wondering what sustainable, high-producing agriculture might look like? This science project explores how analyzing bird's-eye-view pictures of a field can make farmers aware of variations in their fields. Farmers can use this information to optimize their farming practices, or even feed this information to high-tech agricultural equipment so the machines can automatically adjust their actions (like fertilizing or watering) to the needs of a piece of land.

The Wagon Wheel Effect
Science Fair Project Idea
Scientific Method
Have you ever seen a video where it looked like a car's wheels were spinning backward even though the car was driving forward? What about helicopter blades that looked like they were spinning very slowly, or even not moving at all? This illusion is called the "wagon wheel effect," named after old movies where it looked like wagon wheels were spinning backward. In this science project you will learn how the wagon wheel effect works and how you can film it yourself. Read more

Have you ever seen a video where it looked like a car's wheels were spinning backwards even though the car was driving forward? This is called the wagon wheel effect, named after old movies where it looked like wagon wheels were spinning backwards. Even though you cannot see the effect in person, it can show up in videos of spinning objects. Find out why in this project and make your own videos of the wagon wheel effect! Read more
Digital Photos and Dynamic Range
Science Fair Project Idea
Scientific Method
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
Focusing Your Flash for 'Freezing' Motion
Science Fair Project Idea
Scientific Method
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
Image Compression
Science Fair Project Idea
Scientific Method
Compare the strengths and weaknesses of different digital image formats. How does the amount of compression affect a JPEG image? What happens when you save a JPEG image multiple times? Read more
