What is a hypothesis?

How do scientist analyze results?
They use graphs, charts, or tables to help understand data.

To make sure you get the same result every time.
What is a controlled experiment?
An investigation in which scientists change one variable.
What is the purpose of a control group?

What should you do if your hypothesis is not supported?
Re-analyze the data.
Why do scientists use graphs?
