Scientific Method, Lab. Apparatus and Safety Rules Test

What is the first step of the scientific method?

• Formulate a hypothesis

• Conduct experiments

• Ask a question

• Analyze data

A hypothesis is best described as:

• A proven fact

• An educated guess or prediction

• The final conclusion of an experiment

• A random observation
