Who wants to be the teacher!?!?!

Not all things can be learnt from one person.
Who would like to teach the class specific skills?
The first task would be to teach Room 5 how to set up a blogger account in our ICT time.
The "teacher" would need to have the skills to do it, explain it, state learning intentions and the steps to follow.

Task two would be to explain and teach how to email photos, video footage or text directly to our personal blogs from a mobile phone or computer.
This skill would enable us to gather and send data whilst on a fieldtrip, while it's still fresh in our minds. There are other benefits I can imagine. Can anyone think of any to share?

Other teaching tasks will be posted in future. Let's see who the best teachers are!
