Lab Report Outline

Yeast Culture Lab

I. Introduction

1. Briefly introduce the background information of this lab. Define reproduction, consumption, and death in population. Explain the main purpose of the experiment, such as what you will accomplish during the experiment and why it is important to conduct this lab.

2. State your hypothesis of this lab. Your hypothesis must be in an if–then format and include a comparison of at least one variable to the control. Then, in one or two sentences, explain what you expect will happen, and include at least one alternative outcome.

II. Material and Methods

1. List equipment and materials you will use. Cite any worksheets or other reference materials you use.

2. In your own words, create a detailed and numbered list of the steps necessary to complete the experiment. Only include the steps YOU take to complete the lab assignment. You do NOT need to discuss the aspects of the actual laboratory experiment simulation, such as yeast culturing and temperatures.

III. Results

1. List any questions you have about your results.

2. Make both qualitative and quantitative observations.

3. Show your work and remember to include necessary units. Include graphs, when appropriate.

4. Include tables or graphs to summarize your results, if necessary.

IV. Discussion

1. Explain the shape of the population graph for each condition. Why does the graph peak before declining? How do the limiting factors in this experiment affect carrying capacity?

2. What are the phases of the population growth cycle? How does using a simple organism allow for the study of a more complex population?

3. Describe a biogeochemical cycle that had an effect on the yeast cultures by outlining the flow of energy in the cycle.

4. Identify and examine the food chain in a yeast community.

V. Conclusion

1. Accept or reject your hypothesis.

2. State any discrepancies; these are problems or unpredicted events that occurred. These errors may be due to equipment or human error.

3. Based on the lab and your weekly readings, discuss the challenges of studying populations over time.

4. Make suggestions for improvement or for further research.
