A good introduction should include background research and definitions of unfamiliar vocabulary. (3-4 paragraphs) Here you introduce any terms that you may use later in the report.
There needs to be personal engagement (which is your interest in the topic; lie if you must) and a discussion of glycolysis and its relationship to yeast production. The paper I gave you has some general information, but you need to do some more research to beef up this section. This section should end with the following statement: “The purpose of this experiment is to determine the effects of different substrates on the production of carbon dioxide in yeast.”
This should be a general question. Ex: What impact do carbohydrates have on carbon dioxide production in yeast?
You should have already done this part. Remember that you have to rank the substrates in order of greatest production to least production.
State your IV, DV, and control.
A bulleted list of materials.
A list of at least 3 safety precautions in bullet form.
This should be a numbered list. You should recall exactly what you did. The more detailed your steps, the better your grade.
Data Processing & Analysis
Data is qualitative AND quantitative. Qualitative data goes first. Then quantitative data. It should be provided in both a table and graph and then analyzed for trends, and the section should end with a statement on whether the hypothesis was supported or refuted.
Table 1: Effect of Substrates on Yeast Production
Note. The trend between t = 0 and t = 1 shows a rapid increase in dough height for each substrate and the control. However, between t = 1 and t = 2, there is a noticeable decrease in growth for each of the substrates. After t = 2, there is an eventual evening out of the height of the dough, which indicates that yeast production stabilized after approximately six minutes for each substrate, compared to three minutes for the control. According to the data, adding sugar to yeast produces the greatest increase in dough height. Of sugar, starch, and glucose, adding sugar to yeast yields the greatest production of carbon dioxide gas.
Summarize the experiment and tie it in to the introduction. Include this statement: “The hypothesis for this experiment was ________________. The data show that the hypothesis was ______________(supported/refuted).” Then answer the original problem. Support your answer with data but do not use numbers (use
This section should end with a version of the following statement:The next step in further experimentation is to perform this experiment in a heated water bath to see the effects of temperature on the production of yeast with different substrates. (NAME ONE OTHER VARIATION OF THIS EXPERIMENT)
Discuss sources of error. What went wrong and how did it affect your results? What would you change to make this lab more efficient and more effective?
