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…
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.
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.
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…

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.
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.
Did you know that the same digital photo you see on a computer monitor may not look as good in print? When it comes to color profiles, there are a lot of options: RGB, CMYK, grayscale and indexed color! How do you choose the right color profile for the job?
What is it that famous photographers do to make their images so pleasing to the eye? Find out if simple rules of geometry can make you a better photographer.

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!
