doesn't help to discover something if no one else knows

What is the difference between a scientific theory and a scientific law?

Theories describe how or why, laws describe it will happen

What is a hypothesis?

Your conclusion supports your hypothesis...now what?

Repeat the experiment to see if the same happens
