Into the Universe with Stephen Hawking: Time Travel Worksheet (2011)
Hawking delves deep into the concept of time travel, but artfully keeps the conversation interesting and understandable for the students. He uses a logical and scaffolded approach to explain what can sometimes be considered a counter-intuitive and difficult-to-follow concept.
Hawking examines the directional flow of time, how time travel might be achieved, and what are the implications and paradoxes of time travel. On a more scientific note, Hawking discusses how time is applied differently in different special dimensions, the significance of quantum foam, wormholes and radiation feedback, the affect mass has on time, time dilation, the twin’s paradox, relativistic time perspectives, pi-mesons, the warping of space-time, and the fluid nature of the progression of time.
This documentary is appropriate for the following classes: astronomy, physics, general science, and physical science.
The documentary guide is 2 pages long, with a total of 29 higher-order thinking questions. The video is 43 minutes long, designed to be shown in one class with time left over to answer individual student questions or to facilitate a group discussion.

Heya i am for the first time here. I came across
this and it helped me out
much. I hope to give something back and aid others
like you aided me.
Long time supporter, and thought I’d drop a comment. Your site is very sleek.
