Comical Teacher Grading Practices

Great satire about how teachers grade papers is perceived. We all know that most teachers do their best to have accurate assessments, but then again we have all had that one teacher who we felt was not actually grading our work. This might be a fun video to show just before a staff training on proper assessment strategies just to lighten the mood. Be careful though, this might offend some teachers so make sure you know how your staff would react to the video first.

Why do some objects feel colder when in reality they are the same temperature?

In this video pedestrians in a park are asked why a hard drive and a book sitting at the same temperature have a different temperature feel to them.  The hard drive feels colder than the book.  He then takes an aluminum plate and a plastic plate to see which plate melts ice quickly.  Even though the aluminum plate feels colder, it melts the ice quickly.  This is a good experiment to try with your students.
