  • Do you think monarch butterflies migrate on weekends?
  • Describe why you think we often see this pattern.

Our goal is to collect information about the behavior of monarchs. Consider how the behavior of OBSERVERS might affect our results. Keep our method of collecting data in mind.

Make a list of the many ways observers could affect our results. How many can you imagine? Students in Ms. Bailey's class in Vero Beach, Florida thought of 43 examples!
