7. Exp. Method Variable = factor of interest (what you change)
Experimental group

8. Exp. Method
Control group= group that doesn’t receive experimental treatment
Used to compare results

9. Exp. Method 4. Analyze/ organize Data
Data = info gathered from experiment
Use tables and graphs

10. Exp. Method 5. Draw Conclusion
Analyze data and compare outcome with prediction or hypothesis

11. Exp. Method
Conclusion
May not be obvious so repeat experiment
