Quick Draw McPaws: Teach A Computer Kitty How to Draw Shapes
Science Fair Project Idea
Scientific Method
Have you ever played a computer game in which a cartoon character, like a dog or a cat, moves or turns when you click on it? Have you ever wondered how characters know how far to move or how far to turn? In this computer science project, you will learn how with a simple (and free) program called Scratch, which will let you write your own computer program that tells a cartoon kitty how to draw shapes.

Turn Milk into Plastic!
Science Fair Project Idea
Scientific Method
"Plastic made from milk" —that certainly sounds like something made-up. If you agree, you may be surprised to learn that in the early 20th century, milk was used to make many different plastic ornaments —including jewelry for Queen Mary of England! In this chemistry science project, you can figure out the best recipe to make your own milk plastic (usually called casein plastic) and use it to make beads, ornaments, or other items. Read more
Art Bot: Build a Wobbly Robot That Creates Art
Science Fair Project Idea
Scientific Method
Do you like drawing or painting? What if you could build a robot that creates its own art? In this project, you will create your own Art Bot, a robot with markers for "legs" that wobbles across a piece of paper, creating drawings as it moves. You can then customize your robot to change how it draws. This is a beginner-level project with no robotics experience necessary, so if you want to try building your own robot, this is a great place to start! Read more

Does Color Affect Taste?
Science Fair Project Idea
Scientific Method
You might have heard the saying "The eyes eat before the mouth." The appearance of food, especially its color, certainly affects how we perceive its taste. But can your eyes actually change the way you taste something? In this science project, you will find out by investigating how people perceive the taste of different colored apple juice. How do you think color affects taste? Read more
