Evidence of the Big Bang

Evidence of the Big Bang is still present in the universe. This video helps students learn about what evidence there are for the Big Bang.

The Large Hadron Collider Explained

The Newshour on PBS produced a video with a physicist discussing the purpose and importance of the Large Hadron Collider. The video will allow students to better understand the LHC.

Here are some questions that can be used with your students to focus their viewing:

1. Why are scientists doing this?
2. What do you hope they see? Why?
3. Were you satisfied with Greene's answer about black holes? Are you concerned that new science experiments could be more trouble than they are worth, or do you think scientists mostly know what they are doing?
4. How does the public learn about the latest scientific discoveries? How much information should the general public have about scientific experiments? Should we know the details, or just the general goals?
5. Do you want to be a scientist? Why or why not? What kind of education do you think the scientists working on this project have?
6. What do you think about the Big Bang theory? What about the dark matter theory? Is it important for people to understand these theories? Why or why not?
