**[Questions]** 1. What is a hypothesis? An educated guess based on an observation 2. What is a control? An experiment used for comparison to the test group. 3. What is an experiment?                A repeatable test to examine the viability of a hypothesis 4. What is a variable? The things that change within an experiment, only one should change per experiment to ensure reliability. 5\. What happens if your hypothesis does not match your results? You can revisit your hypothesis and change it, or you can redesign your experiment. 5. Where do scientists publish their results to be evaluated by peers? Scientific journals 6. What is a replicate? Repeats of an experiment to guarantee statistical reliability. 7. What is a theory? An explanation to proving a hypothesis correct that has been tested and proven to be correct many times. 8. What is a principle? A theory that has been tested and proven to be correct for a long time. 9. Define double-blind testing. An experiment whereby both the tester and patient are unsure if they are in the placebo or test group. 10. What is the purpose of double-blind testing? To reduce bias in an experiment. 11. State two principles of good experimentation. Large sample size, use of a control group. 12. State two limitations of scientific knowledge. Accidental discoveries and misinterpretation of results.
