Jamie and Adam TESTED is a site from Mythbusters Jaime and Adam. The site explores new breakthroughs and topics in science and engineering, exploration, nature, emerging technologies and new products. They explore these topics in depth, including the hows and whys about them.
There are articles, links, videos and much more about all these topics. It's a great resource for STEM classes to get topic ideas, research, news, and to learn some cool things. There are even some pretty cool how-to videos and articles to do some pretty interesting things.
I've found some great things to use with my Physics classes and gotten some great ideas for projects.
Check it out and share it with your students and colleagues. http://www.tested.com
