Answer the following questions in complete, quality and correct sentences reflecting each question on a separate sheet of paper.

Part A - Prelab Section (55 pts)

1. (5 pts) Tell the study subject in this experiment.

2. (5 pts) What is the Manipulated (experimental) variable in this experiment?

3. (5 pts) Describe the Responding (measured) Variable.

4. (5 pts) Identify which of the trials are the control trials. Why are these the control trials?

5. (5 pts) Tell which are the experimental trials. Tell why these are the experimental trials.

6. (10 pts) Create a properly formatted scientific question for this experiment, (SS, MV, RV)

7. (10 pts) Write an appropriate prediction for this question. (If, Then - Compared to FORMAT)

8. (10 pts) Create a properly formatted hypothesis for this experiment. (If,Then - Compared to, Because FORMAT)

Part B - Post Lab Section (95 pts)

9. (25 pts) Create a CQC Data Table using the class data. Circle the High and Low Differences. Double check all calculations.

10. (10 pts) Describe 2 controlled variables for this experiment and tell why these are controlled (Not the MV or RV!).

11. (10 pts) Tell 2 likely sources of error in this experiment (Do not use recording or calculation error) AND tell how each source could have affected the outcome.

12. (10 pt) Describe 1 potential uncontrolled variable and tell how this variable could or did affect the data. (Not the MV or RV!).

13. Conclusion (40 pts). Follow this format:

a. Tell the Question being investigated

b. State The Hypothesis

c. Tell if the Hypothesis was Accepted, Rejected.

d. Explain why the Hypothesis was Accepted or Rejected. As a minimum, use this data to explain why.

i. Use the AVERAGE (units!)

ii. Use the Range to accurately explain the quality of the data gathered.

1. Range = High - Low

2. The higher the range of data generally means higher error in the data

e. Explain what was done to improve the Reliability of this experimental data.

f. Tell what you learned in at least 3 meaningful sentences. Potential topics:

i. Something you learned about the experimental process

ii. Working as a team member.

iii. A related experiment you'd like to do in the future and what you expect to learn for this.
