In this laboratory exercise, students examine hypotheses about the interactions between goldenrod plants and the gall-forming insects that feed on them. Students collect and analyze data to determine 1) whether certain traits make the plants more susceptible to attack by the insects and 2) how plant reproduction is affected by the insects' feeding. Students are introduced to several competing hypotheses that they evaluate using their data and previous research.

Pedagogical Use Description Teachers can use this activity to teach students about plant-herbivore interactions and the scientific method. Students collect and analyze data to evaluate several conflicting hypotheses. This activity could be used to lead into a discussion about how scientists determine which hypothesis among several others is best supported by evidence. Teachers could also prompt discussion on whether students would expect the same hypothesis to be supported in varying growing conditions.
