If the control variable is not given, suggest a possible controlled variable. 1) The number of flowers on different breeds of rose bushes in a greenhouse is recorded every week for two months.

The "Teacher's Answer Key: Evaluating experiments worksheet" resource attached to this section can be used as students work on providing the basic information (independent and dependent variables, hypothesis, etc.) for each scenario, but I think it is most useful here as a way to guide the discussion of how the experiments could be improved.
