What do you start with in an experiment?
Always start with your question!

2. Research the topic
3. Form hypothesis
4. Test the hypothesis
5. Gather Data
6. Analyze results

YES!
The group that is used for comparison and does not get the independent variable.
What is the control group?
What are qualitative observations?
Anything that you hear, see, taste, or smell
4th step?
Apply error analysis. Think about your research and consider any improvements to your procedure.
Fifth Step?
Offer explanations for why you think the results of your experiment were why they were.
