Explain It To Me Explains Iran

I'm kind of hooked on CNN's Explain It To Me series of videos. Each video offers a nice, succinct explanation of topics in the news. One that I watched early this morning is an explanation of Iran's nuclear program and the concerns it causes. The short video is appropriate for use with high school students in a current world news course.



To follow-up on the video above, ThinkFinity has a good list of lesson plans for teaching about nuclear energy. Here is a short video explanation of how a nuclear reactor works.

Explain It To Me Explains Concussions

When I was playing sports in school I don't think anyone ever mentioned the word concussion to us. Subsequently, I'm sure that one or more of my classmates had undiagnosed concussions. Fortunately, that is not the case for today's student-athletes. Today, we hear about concussions in professional and amateur athletes quite frequently. But what is a concussion and how do they happen? Dr. Sanjay Gupta explains the answers to those questions and more in the episode of CNN's Explain It To Me series embedded below.

Video - What is an IPO?

The tech and business worlds have been buzzing all week about the seemingly impending Facebook IPO. Your students may have heard about it too. This would be a good a time to teach students about how companies end up on the stock market and why they offer shares in their companies. CNN's Explain It To Me series has a new video explaining what an IPO is and why companies like Facebook put shares up for sale. The video is embedded below or you can watch it here.
