It's the Electricity Song!
Can you determine from the song the;-
- source of electricity/electrical energy
- where the electricity from our house come from
- what devices in your home can convert electrical energy?
- what forms of energy can electricity be transformed/ converted to?
- what is the difference between static and current electricity?

Snippets from SuperKids
title on the slide: 'I am gifted. So are you."
Self-esteem. My favourite topic :)

The Day the Moodle Crash - Main Suspect? Chat module
While using the Chat module in the new Moodle 2.0, my account got suspended temporarily. I will not be using the Chat module in the foreseeable future. This is the first time I have experienced this.
I think I will need to find a free third party chat module.
