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 Worksheet

"Cosmos" season 1, episode 2 titled "Some of the Things That Molecules Do," 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.

The evolution of the eye is explored, and DNA, genes and mutation are discussed, as is abiogenesis—the origin of life from nonorganic matter.

Tyson looks at the five great extinction events and how the micro-animal tardigrade survived them all.

The episode also covers selective breeding, including how humans transformed wolves into dogs.

The following questions can be used to assess how much the students retained. 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.
