Scientific Method

Got a hunch about something but don’t know how to prove it? In this BrainPOP movie, Tim and Moby will walk you through the steps of the scientific method, which can be used to design any kind of experiment! First, Tim will show you how to make observations and develop inferences based on them. Then, you’ll learn how to form a hypothesis, make a prediction, and design a test to see whether or not your prediction was correct. Finally, you’ll learn why it’s important for others to be able to repeat your experiment! You’ll also learn how hypotheses become theories, and why there’s really no such thing as a scientific fact! So don’t just take a wild guess -- use the scientific method and be sure!
