Cosmos Episode 13 Viewing Worksheet

Neil DeGrasse Tyson in front of a projection of Earth

As a teacher, I am always on the lookout for great science videos to show my classes. I use these either as a supplement to help enhance a topic we are learning or sometimes as a reward for the students on a "movie day". They also come in handy when I have to plan for a substitute teacher to take over my classes for a day. It isn't always easy to find something relevant, educational, and entertaining. Thankfully, Fox brought back the "Cosmos" series and updated it using the awesome Neil deGrasse Tyson as host. I now have a whole series of outstanding science shows to show the students.

However, I need to make sure the students understand and absorb the material. Below is a set of questions for Cosmos Episode 13, entitled "Unafraid of the Dark", that can be copy and pasted (and then tweaked as necessary) into a worksheet. It can be used as a note taking guide while watching the show, or afterward as a type of quiz or informal assessment.
