• Is not based on research and is not testable

• Is a type of Earth/Space science

• Representations of objects or processes that are not easily observable

• Fashion models who are also scientists

• Testable ideas or explanations that lead to scientific invstigation

The correct sequence of steps in the scientific method are

• collect data, analyze data, draw conclusions

• plan an experiment, analyze results, form a hypothesis

• draw conclusions, plan an experiment, collect data

• perform an experiment, ask a question, collect data

A scientist uses another scientist's procedures to perform the same experiment. This is an example of

• pseudoscience

• repetition

• replication

• analyzing data

Graphs are important because

• they show data in a visual way

• they prove the results of an experiment

• they make the data more interesting

• they really are not important
