This online exhibit from the Lemenson Center includes Invention Playhouse. The Tinker Ball game in particular is a great physics based interactive. The site also includes Inventors' Stories and a section called Does Play Matter? How have attitudes toward play changed over time? What kinds of toys did inventors play with as children? Is the quality and quantity of children's play changing? If play is changing, how will that affect invention? Reflect upon these and other questions through video commentaries and toy displays

The presentations on this site were originally inspired by Tom Barrett's 'Interesting Ways' presentations. These Google Docs presentations were created by Tom, with lots of contributions from the fantastic teachers who read his blog and are part of his Twitter network. Mark Warner decided to try something similar, based upon 'Amazing Ways to Inspire Writing'. He was really pleased with the response, in terms of contributions from others, and positive comments about the idea and thought that it was worth making a site to host the presentations, rather than relying on people to remember long and complicated Google Docs addresses. Tom, Doug Belshaw and Joe Rowing have also kindly given their permission for their 'Interesting Ways' presentations to be embedded here for others to see. If you have any amazing ideas to add to the presentations on the site, or you can suggest a new topic, please get in touch, via email or Twitter.

This site proves it beyond a shadow of a doubt. Books have been ruining history. So many unnecessary words. Now, with Historical Tweets, history's most amazing men and women can be fully understood, a mere 140 characters at a time.

Quote "Schools must be proactive, rather than merely defensive, in helping students acquire the skills of digital citizenship needed today and in the future. Simply banning read/write web tools on school networks is an inadequate response: Educators must strive to learn alongside students and parents how these technologies can be safely and powerfully used to communicate and collaborate."
