Answer the following prompt as a CER:
Next year, when we create our small Daphnia ecosystems in 3 Liter bottles, how much food should we
put in for each feeding?
Write a paragraph that explains the findings from our Daphnia experiment. Use the data and graph we
created as evidence to support your claim.
Claim
First, make a statement to answer the prompt.
Evidence
Next, summarize briefly the experiment (What did we do?)
Then, give specific examples from the data and the graph to support
your claim (What did we learn in the experiment?).
Reasoning
Finally, explain how the evidence you gave supports your claim. Why do
you believe what you wrote in your claim?
