• scientific method
• experiment

A hypothesis is simply a prediction that has not yet been _.

• supported or not
• made into a theory
• results calculated
• written about

The factors in an experiment that can be changed. 

• variables
• quantitative data
• hypothesis
• steps

In a controlled experiment, how many variables can be worked with at a time? 

• one

• two or more
• how ever many makes sense.

This part of the experiment serves as a basis of comparison; the one variable being tested has been omitted. 

• experimental group
• control group
• data
• variables

This part of the experiment shows the effect of the one variable being tested. 

• control group
• experimental group
• quantitative data
• hypothesis

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

• dependent variable
• independent variable
• data
• control group
