Just-in-Time Teaching (JiTT) WarmUp Activity: Life in the Sahara Desert

Laura Guertin, Penn State University Delaware County
Author Profile

Question:

1) What the Sahara always a desert? How do we know? (*NOTE: for this question, I want you to focus on the physical environment)

2) What modern-day animals can be found in the desert? How do they survive?

3) Why have humans - past and present - gone into the Sahara Desert?

Student Responses:

See the Just-in-Time Teaching page on assessment for information and ideas on how to evaluate student responses.

Students will question the Sahara Desert in the context of geologic time and share that they are surprised that the desert was not always a desert. Students show surprise that life does exist in the desert, both human and animal. Instructors should prepare for questions about what is a sandstorm and an oasis.
