Learning Aims:
  • Further experiments to find out which of both scenarios is most likelyeflecting on the students’ knowledge of physics to apply to this case.
Materials:
To be decided by the students

    Suggestions for use:
    • Classroom discussion as introduction to the subject.
    • Emphasize that further research is needed when the research thus far is not sufficient to draw a definitive conclusion.
    • Address the fact that there are still doubts in this case, sometimes this is inevitable.
    • Which other effects might occur in this case? How can this be demonstrated?
    • If it is difficult for the students to plan the experiments, activity 1.6 might be done first, followed by activity 1.5 . In that case it is a more guided inquiry: find an experiment that demonstrates the telescoping effect.
    Possible questions:
    • Are there other facts that might be investigated further?
