Just-in-Time Teaching (JiTT) WarmUp Activity: Darwin's Garden

Laura Guertin, Penn State University Delaware County
Author Profile

Question:

1) Why does biodiversity in an ecosystem "matter"?

2) Describe Darwin's garden experiment and the significance of it.

3) So Darwin figured out the connection between biodiversity and ecosystem health - back in the 1800's. But scientists have only been studying the connection between biodiversity and ecosystem functioning for approximately 10 years. Why do you think Darwin's experiment was "forgotten" all these years? Why do you think it took this long for modern-day scientists to make the same connection Darwin did years and years before?

Student Responses:
