S1. Introduction (1-2 paragraphs) – Briefly describe the process of cellular respiration. – Summarize the experiment you conducted in class using seeds to examine rates of cellular respiration. Be sure to address the following questions: What hypothesis was being tested? How did you test your hypothesis? What independent and dependent variables were being investigated? What controls did you use? What were possible sources of error in your experiment? Please explain how the experiment you conducted supported or failed to support the original hypothesis. – Describe the experiment you are proposing in general terms and how it relates to the process of cell respiration.
2. Question & Claim/Hypothesis (2-3 paragraphs) – What specific question will you address? The question should be about the relationship between the rate of cellular respiration
3. Evidence/Experimental Design (2-3 paragraphs) – Describe in detail the experimental design that you will use to test your hypothesis. In other words, how will you gather evidence to support your claim/hypothesis?
4. Expected Results (2-3 paragraphs) – Make a table using Word, Excel, or another digital format of your expected results. – Label one column with your independent variable and another column with the dependent variable (rate of cellular respiration) – Add imaginary values for the independent variable (make sure you use appropriate units) that cover a reasonable range. That is, for whatever independent variable that you chose, your experiment should cover a range from low to high values of the chosen independent variable. – Then, and imaginary values for the dependent variable (with units/time) based on your claim/hypothesis and predictions. Refer to the results of the cellular respiration experiment you just conducted to come up with reasonable hypothetical data for your proposed experiment. – Graph your hypothetical results, using a digital program (Excel or another) to show the relationship you would expect.
5. Reasoning (2-3 paragraphs) – Describe your reasoning in detail. This is the most important part of any experiment! Look at the section titled “CER” at the end of this document to understand what reasoning is and how to write this section. Your reasoning should address the following:
3 o What was the reason that you thought your independent variable would affect the dependent? That is, what cell structures do you think would be affected by the independent variable you chose? (Think of enzymes, membranes, organelles, etc.) o What was the reason for the relationship you chose? That is, why did you think the independent variable would make the dependent increase or decrease? o What would the results (and graph) look if they did NOT support your claim/hypothesis?
6. Integrative Learning (2-3 paragraphs) How does what you have done connect to / compliment a different piece of learning in a Chemistry or Math Class (or a non-science class)? That is, can you connect this to something you have learned in another class, and how? – this are valuable to understanding a topic. – If you wanted to turn this into a grant proposal, you would have to include many practical details such as the equipment needed, the amount of time that it would take, and any problems you might encounter. Describe one possible problem with actually doing the experiment you designed.
