Next Topic: Logo!

In order to get a good introduction to the Logo commands please watch this video, pausing it at various points to do what the person just did:




Good luck!

Ergonomics, Health and Safety

On November 21st we are going to discuss computer health and safety. Here are some videos to help us understand the topic:

A Major Concern: Carpal Tunnel Syndrome

The Science Of Ergonomics

Note: Mr. Matsumoto has one of the physio balls she discusses. If you want to try it out go to his office and ask him for a demonstration. I am sure he wouldn`t mind showing you.
