Can Humans Recognize AI-Generated Images?

Science Fair Project Idea

Scientific Method

Can you tell if the pictures on this page are real or generated by a computer? Artificial intelligence (AI) generated images have exploded in popularity, bringing plenty of controversy along with them. An AI-generated image of a tiger or a flower might seem harmless, but artificial images of people or events can contribute to "fake news." In this science project you will investigate whether people can tell the difference between real pictures and pictures generated by AI. Can you spot the… Read more

Build a Gauss Rifle!

Science Fair Project Idea

Scientific Method

What can you do with magnets and ball bearings that makes a lot of noise? Why, build a magnetic linear accelerator, called a Gauss rifle, of course! Now, this magnetic accelerator is not a weapon, but a way for you to learn a lot more about physics concepts, like momentum. In this physics science project, you will investigate how far a ball bearing launched by a Gauss rifle will fly, depending on how many magnetic acceleration stages are in the setup and the ball bearing's initial velocity.… Read more

Crazy Crystal Creations: How to Grow the Best and the Largest Crystals

Science Fair Project Idea

Scientific Method

Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals. Read more
