Turn "Does smoking cause lung cancer" into a hypothesis
If you msoke then you will probably get lung cancer because the smoke will ruin your lungs

- 2. Make question
- 3. Make prediciton that can be tested
- 4. Make hypothesis.
- 5. Test hypothesis
- 6. REcord data and analyze
- 7. Analyze the expiriment make a conclusion
- 8. Repeat
- 9. Communicate results
What is a control group and why is it useful
The contorl group is where the manipulated variable is not mainpulated. Userful for comparing with the expiriment to compare results and to ensure that your results were not caused by some other uncontrolled varilabe.

What did Galileo do
Created and practiced the science of dynamics and expiriments
