Procedure:
A summary that explains what you did and how you did it. This section should not be a strict paraphrasing of the procedures described in the lab sheet and in your lab journal.
|
- Labeled Procedure - A clearly written paragraph summarizing what was done in the lab (in your own words) - Written in 3rd person Òpoint of view, no use of personal pronouns – like ÒIÓ, ÒweÓ, or ÒyouÓ - Maintains the same verb tense throughout paragraph |
- Labeled Procedure - A clearly written paragraph, incorporating phrase from the lab sheet, summarizing what was done in the lab - Written in 3rd person Òpoint of view, no use of personal pronouns – like ÒIÓ, ÒweÓ, or ÒyouÓ - Maintains the same verb tense throughout paragraph |
- Labeled Procedure - A clearly written paragraph, incorporating phrase from the lab sheet, summarizing what was done in the lab - Attempt is made to write in 3rd person Ôpoint of viewÓ Pronouns like ÒIÓ, ÒweÓ, or ÒyouÓ are used two or three times. |
- Label not clearly written or present. - Paragraph formatting is not followed. Tendency toward itemizing steps. - Consistent use of personal pronouns - Verb tenses vary from past to present
|
|
Data:
Includes data collected clearly organized.
POINTS X2 |
- Labeled Data - Quantitative observations are clearly organized in a data table. - Measurements are recorded using the correct number of significant digits and proper units. - Qualitative observations are described in a data table |

Conclusion:
A discussion of the details of your experiment, the results, and what you learned from them. Really think about the experiment. Be creative and original in analyzing your results. Be careful of your own bias and do not let it slant your conclusions. If you expected a result and did not get it, determine whether the problem was in your technique or in your expectations. Be objective. Your conclusion response should show a thorough understanding of the principles involved in the experiment.
POINTS X2 |
- Labeled Conclusion - A clear, well-written response to the experiment. It should answer the four sets of questions in paragraph format: 1. What are the results of your experiment? (Discuss data/obs) 2. What do the results mean? How do they relate to the principle being tested? (Interpretation of calculations, data, interesting or unexpected observations.) 3. Did you achieve the expected results? Did the results match your hypothesis? Why or why not? 4. Are your results valid? Was there something that you did during the experiment that may have affected your outcome? (Suggest improvements in the techniques. How might you do the lab differently? Do not be afraid to criticize and add your own creative input.) - Refers to and incorporates the answers to the questions on the lab sheet within the conclusion response
|
- Labeled Conclusion - A clear, well-written response to the experiment. It should answer the three sets of questions in paragraph format: 1. What are the results of your experiment? (Discuss data/obs) 2. What do the results mean? How do they relate to the principle being tested? (Interpretation of calculations, data, interesting or unexpected observations.) 3. Did you achieve the expected results? Did the results match your hypothesis? Why or why not? - Refers to and incorporates the answers to the questions on the lab sheet within the conclusion response
|
- Labeled Conclusion - A clear, well-written response to the experiment. It should answer at least two of the following questions in paragraph format: 1. What are the results of your experiment? (Discuss data/obs) 2. What do the results mean? How do they relate to the principle being tested? (Interpretation of calculations, data, interesting or unexpected observations.) 3. Did you achieve the expected results? Did the results match your hypothesis? - Refers to and itemizes the answers to the questions on the lab sheet at the end of the conclusion response
|
- Label not clearly written or present. - A clear, well-written response to the experiment. It should answer at least one of the following questions in paragraph format. 1.
