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.
Can you make water fall up? Or make drops of water hover in mid-air? While you might not be able to make water defy gravity, you can create the illusion that it does using something called the stroboscopic effect. In this project you will make use of the stroboscopic effect to build your own "levitating water" fountain.
Build your own strobe light using an Arduino and an LED strip. Use it to demonstrate the stroboscopic effect.
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…
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.
Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the…
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.
Do you like to take pictures with a camera? It can be fun to capture important and humorous events in your life on film or on a memory card. Photography is a hobby that people of all ages enjoy because they can creatively express themselves both artistically and scientifically. But when did the science of photography start and have cameras always been such complicated pieces of equipment? In this photography science project, you will experiment with a simple camera called a pinhole camera and…
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.
Helicopters are fascinating to watch. The spinning rotor blades on top of the helicopter generate lift, allowing it to take off vertically. They can land vertically, too, allowing them to set down in small spaces, such as hospital helipads or on a ship at sea. In this aerodynamics science fair project, you will fly a remote-controlled helicopter and measure how the rate of the rotor's rotation changes as the helicopter hovers and flies up or down.
