Q

What are the four steps to making a theory?

A

Hypothesis- Explain why things happen and used to make a prediction
Make a prediction-What do you expect to observe
Test your prediction-use an experiment to make an observation
Repeat the experiment serveral times to test it-if it holds up it becomes a theory
