Goldenrod Galls

(1 review)


This lesson teaches students about the coevolution of goldenrods, their predators, and the parasites of their predators. Looking at galls is a great late fall activity, since it allows fieldwork and specimen collection late in the year.

Students develop testable hypotheses about natural selection in the goldenrod-gall fly system, collect galls, and test their hypotheses. This lesson also includes a guide to the statistics needed to calculate a t-test, making it a valuable resource for math education.

    It can be difficult to find field experiments for late fall and winter, so this lesson with goldenrod galls is very useful. Goldenrod is common in early field succession communities, so usually plentiful in the north east USA.

    This lesson is written for college students, but could be adapted for advanced high school students with a bit of work. We really like the clear instructions for a laboratory report based on the students’ work, and examples of potential testable hypotheses.
