Cosmos: A Spacetime Odyssey Episode 9. (FOX)

Great educators know that in order for all students to learn, they need to adjust their teaching style to accommodate all types of learners. This means there needs to be an assortment of ways that content and topics are introduced and reinforced for the students. One way this can be accomplished is through videos.

Luckily, Fox has come out with an amazingly entertaining and extremely accurate science series called Cosmos: A Spacetime Odyssey, hosted by the very likable Neil deGrasse Tyson. He makes learning science fun and accessible for all levels of learners. Whether the episodes are used to supplement a lesson, as a review for a topic or unit of study, or as a reward, teachers in all science subjects should be encouraging their students to watch the show.

If you are looking for a way to assess understanding or what the students were paying attention to during Cosmos Episode 9, called "The Lost Worlds of Earth," here is a worksheet you can use as a viewing guide, a note-taking worksheet, or even a post-video quiz. Just copy-and-paste the worksheet below and tweak as you feel is necessary.
