The organism you used is Nannochloropsis oculata. Note that the genus name (Nannochloropsis) is capitalized and the species name (oculata) is not. Both are italicized.

(Informative title) (The Relationship between (IV) and (DV))

ExperimentalDesign:

Research Question: What is the effect of the IV on the DV?

Null Hypothesis: The IV will not affect the DV

Alternative Hypothesis 1:

Alternative Hypothesis 2:

Independent Variable (IV):

Experimental groups: include all groups. Be specific (not ‘room temperature’, but ‘21oC’)

Control group:

Dependent Variable (DV): what is being measured, how it is being measured, units

Constants: Refer to your model for important constants.

Results:In paragraph format, discuss the following:

  • Make a claim: Write a statement that answers the research question.
  • Summarize trends in the data. According to the graph, which experimental group produced highest DO or consumed least DO? which experimental group produced lowest DO or consumed the most DO?

(Refer to central tendency and variation (standard deviation)).

  • Calculate & compare rate - Use the mean class data from excel sheet

oxygen produced ÷ time (include units)

  • Restate the null hypothesis. Was the null hypothesis accepted or rejected?
  • Restate the alternative hypotheses, and state if each of the alternative hypothesis was supported or notsupported (DO NOTwrite “proven”).
  • Check your work to make sure you did not use any personal pronouns or contractions. Be specific. Use scientific writing. Do not just make lists. Capitalize proper nouns. Do not capitalize common nouns.
  • Data table needs (a) a descriptive title (title case), (b) headings, (c) means, and (d) standard deviation, and (e) units for both (both units are the same).
  • Insert a picture of your hand-drawn graph here. The graph will be graded in your lab notebook.

Discussion:

In paragraph format, discuss the following:

  • Restate the claim to focus the reader on the answer to the research question.
  • What is THE REASON (highest/lowest change in DO) - explain the scientific concepts behind the claim so that readers understand how the new information fits into current knowledge – This will be the main part of the discussion section – it will require at least one paragraph to explain the light-dependent reactions. Explain fully and be specific.
  • You are trying to show the connection between the IV and the DV. Why did the IV cause and increase or decrease in oxygen produced. Be specific and explain using your knowledge of the light dependent reactions.
  • Convince me that you know how photosynthesis works
  • how oxygen is made in photosynthesis
  • why the IV caused a change in the DV
  • Explain any negative values.
  • Error analysis – if any of the data is unexpected try to understand why

Summarize everything and answer the research question - 3-4 sentences only. Refer back to the original overall research question involving maximizing oil production in N. oculata.
