What is the collection of facts (numbers, measurements, words, observations)

• Experiment

• Data

• Hypothesis

• Observation

A possible explanation to a problem that has not yet been tested. 

• data
• theory
• hypothesis
• fact

This variable in an experiment is the one being deliberately changed by the scientist. 

• dependent variable
• independent variable
• data
• control group

What step does every scientific experiment begin with?

• hypothesis
• question/problem
• procedures
• conclusion
