• question/problem
• procedures
• conclusion

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

Why do we want to test only one independent variable at a time?

• Because it is hard to setup a data table with more than one variable
• To better identify what is causing the changes
• It is what has always been done
• It's easier to perform the experiment
