How are predictions used in the scientific process?

• to help scientists test hypotheses

• to help scientists communicate results

• to help scientists analyze data

• to help scientists formulate theories

Which of the following is a method of analyzing data?

• stating a problem

• doing a calculation

• revising a hypothesis

• making a prediction

In which case would you revise a hypothesis?

• when you have no prior knowledge of a subject

• when you do not have enough data to make a graph

• when your experimental design does not work

• when experimental results do not support the original hypothesis

Which type of scientist studies the subject illustrated here?

• life scientist

• Earth scientist

• physical scientist

Why is the theory of plate tectonics called a scientific theory?

• because it is a rule that describes a pattern in nature

• because it is an explanation based on many observations and investigations

• because it is information gathered by using the senses

• because it is a statement of what will happen next
