Bio 102 Daphnia Lab Report 20 Points
Overall: The report must be typed with a font size of 12. It should be about 4 pages long.
No headings = Minus 2. Egregious grammar and/or spelling errors = Minus 2
1pt. Student’s First and Last name
1 pt. Title. A good, descriptive title.
4 pts. Introduction:
What is the aim of the experiment? What is a Daphnia exactly? Why is Daphnia a particularly good animal to use for these experiments? What does ectothermic mean? Include background information that supports the hypotheses. Cite at least two sources/references within the text.
1 pt: Hypothesis:
Write a predictive statement about the effect of temperature.
2 pts Material and Methods:
Don’t write a list. Use proper level of detail, .It should be between ½ a page and 1 page long. Use first person, past tense and cite the lab manual.
5 pts Results: Write a brief sentence in which you summarize what happened with change in temperature. No explanations or interpretation of the data.
Calculate the percent change in heart rate with increase in temperature and in decrease in temperature.
Include the data tables.
Draw a bar graph using calibrated graph paper or graphing software. On the graph – plot ONLY the average heart rate. Use heart rate per minute (not per 15seconds). The graph needs a proper title and labeled axes. For the temperature graph – the X axis must be temperature in increasing order from zero.
3 pts Discussion:
Were the changes in heart rate significant or very slight? Did your Daphnia die? Was it carrying eggs? Discuss any errors made. Interpret and explain your results – were your results what you expected? Why or why not?
1 pt Conclusion:
“The data supported the hypothesis” OR “The data did not support the hypothesis”
2 pts Literature Cited:
Correct format MLA format (see NVCC Alexandria Library web site for help with citation format). At least two references. Wikipedia is not a source
