 The Fox television series "Cosmos: A Spacetime Odyssey" hosted by Neil deGrasse Tyson is an excellent way for students at the high school, and even the middle school, level to supplement their learning on various science topics. With episodes that cover almost all of the major disciplines in science, teachers are able to use these shows along with their curriculum to make the topics more accessible and even exciting for learners of all levels.

Cosmos episode 4 was mostly focused on Astronomy topics, including star formation and death and black holes. There are also some great illustrations about the effects of gravity. It would be a nice addition to an Earth or Space Science class or even Physics classes that touch on the study of Astronomy as a supplement to the students' learning.

Teachers need to have a way to assess whether a student is paying attention and learning during a video. Let's face it, if you turn the lights down and have soothing music, it is easy to doze off or daydream. Hopefully, the questions below will help keep the students on task and allow teachers to assess whether or not they understood and were paying attention.  The questions can be copy and pasted into a worksheet and modified to fit the needs of the class.
