First of all, here is the original worksheet. There are two versions on this website... we did the lab WITHOUT the chlorophyll extract.

(No Chlorophyll Extract)

#BioDub Lab Discussion Notes - Examining the Light Reaction
Please review the following as you are TYPING/reviewing your lab report:
Title: Use the same title from the worksheet...no need to be creative.
Objective: Retype the objective you wrote on the worksheet. Remember, NO I's, MY's, WE's, and OUR's! Type the objective not from a personal perspective, but from a "matter of fact" perspective. I am aware the the last line of the introduction has a "We' in it. When you type your lab report, reword your objective so that it does NOT include the "We".
Hypothesis: Retype the hypothesis you wrote on the worksheet. A good hypothesis not only predicts what will happen, but offers a reason why.
Remember, NO I's, MY's, WE's, and OUR's!
Materials: Copy the list of materials from the worksheet. Arrange in column format, ideally in two or more columns. Remember, we used a salt solution, not a sugar solution.
Procedure: Copy the procedure from the worksheet (it is not plagiarizing if I give you permission). You can literally cut-and-paste from the worksheet above. Remember, we used a salt solution, not a sugar solution.
Results: Create tables for your results. For this lab, one table should be sufficient. I would include the following in your table: test tube number, test tube description (contents, treatment, etc.), initial color before 30 minute test, final color after 30 minute test.
Discussion: In paragraph form (at least 2 of them) do the following:
Conclusion: The conclusion should be short, but sweet. That aside, it is just as important as the discussion. In one paragraph:

Discussion: In paragraph form (at least 2 of them) do the following:
- Thoroughly explain the results... almost to the point where you imaging the reader cannot understand them just by looking at your tables.
- For each test tube, not only explain what change occurred, but offer a realistic cause for the change. Be specific.
- Your last paragraph(s) in the discussion should be the error analysis. Remember error is not mistakes... error include factors that you cannot control which may have affected your results. Ideally identify 3 sources of error, explain their potential effect on your data, and offer a possible remedy, even if it is somewhat far-fetched.
- Remember, NO I's, MY's, WE's, and OUR's!
Conclusion: The conclusion should be short, but sweet. That aside, it is just as important as the discussion. In one paragraph:
- Mention the objective. Confirm that the objective was met by quickly stating the results that address the objective.
- Mention the hypothesis. Address the accuracy of the hypothesis by comparing it to the results. If it is correct, identify it as correct and explain. If it is partially correct, identify it as partially correct and explain. If it was completely incorrect, identify it as incorrect and explain.
- Remember, NO I's, MY's, WE's, and OUR's!
