Cosmos Episode 2 Viewing Worksheet

 As a teacher, it is important to use all different types of curriculum delivery in order to reach all types of learners in your classroom. One way you can get your point across in a way that seems more fun for most students is through videos. The series "Cosmos: A Spacetime Odyssey" hosted by Neil deGrasse Tyson does an excellent job of breaking down various science topics in an accessible way for even beginning learners.

Cosmos season 1 episode 2 was focused on telling the story of evolution. Showing the episode to a middle school or high school level class is a great way to introduce the Theory of Evolution and Natural Selection to students. However, as a teacher, a way to assess whether or not they understood or retained any information is an important step in the process. The following questions can be used as a way to do that sort of assessment. They can be copied and pasted into a worksheet and then modified as necessary. Giving the worksheet out to fill in as they watch, or even after viewing, will give the teacher a good view of what the students understood and heard and what was missed or misunderstood.
