Questions Answer each question with CQC sentences and data on a separate sheet of paper.. Be sure to reflect the question
- Part A: Pre
Lab Questions (60pts)
1. (5 pts) What is the study subject of this experiment?
2. (5 pts) What is the manipulated variable in this experiment?
3. (5 pts) Describe the Responding Variable.
4a. (5 pts) Explain what type of food and which lab station is being used for the class's Control.
4b. (5 pts) What will YOUR TEAM's experimental trial be?
5. (5 pts) Describe how the class will get the experimental data for this experiment.
6. (10 pts) What scientific question is being investigated in this experiment? (-ss,mv,rv-)
7. (10 pts) Create an appropriate prediction for this question. (IF Then Compared to FORMAT)
8. (10 pts) Develop an appropriate hypothesis for the above question. (If Then Compared to Because - SS,MV,RV, & WHY FORMAT)
Part B: Post Lab Questions (195 pts)
9. (10 pts) Tell 1 controlled variable that matters and tell why it was controlled (Not MV or RV!)
10. (10 pts) Name/describe two sources of Error that matter and explain how each did or could have occurred in this lab.
11. (10 pts) Tell 2 uncontrolled variables that matter and why each matters and how this variable could or did affect the results of the experiment. (Not MV or RV!)
12. (10 pts) Evaluate the reliability of the experimental data and how the experiment can be made more reliable.
13. (10 pts) Describe a second set of trials that one could do to improve the validity of this experiment.
14. (50 pts) Create and attached a properly formatted and correctly calculated CQC Data table displaying the class's data.
· Be sure to double check all calculations!
· Put a "H" by the High and "L" by the Low Mass Loss/Gain %.
15. (80pts) Develop a descriptive Conclusion for this experiment
a. (5pt) Tell the question the class was investigating.
b. (5pt) State the hypothesis that your team is testing. (Continued on back)
c. (10 pts) Tell if this hypothesis was Accepted or Rejected
d. (40pt) Explanation below: (USE UNITS EACH TIME DATA IS QUOTED.
- i.
(10
pts)
Completely explain why you answered what you did in 15c.
above AND use the following data
ii. (10 pts) The Loss/Gain % of the three trials with best results AND compare these to the class's control. (Tell how much more or less compared to the control)
iii. (10 pts) The two best types of food to feed redworms and the absolute worst.
iv. (10 pts) Tell the High, Low & Range (in Loss/Gain %) of the class's data and .
(A high range of data for a set of trials often reveals potential errors.)
e. (20pt) Summarize the experiment. (Should be at least 5+ meaningful sentences!) Be specific; use examples of data (units!). YOU MUST:
- i. Tell one new thing
you learned (or understood more clearly) about
Experimental design by doing this experiment.
ii. Tell a safety precaution that needs to be followed to do this job safely.
iii. Write a final conclusive statement that will help someone interested in raising redworms know what to feed their worms.
16. (15pt) Extension Question: Analyze the experiment shown. What mistake in experimental design was made in this experiment??
