This is a pretty good video I found on google video – it contains some good Chemistry atall levels (pre IB, SL and HL) and from a number of topics (eg, periodicity, atomic structure) and even some TOK.
I hope you enjoy it!

Google and Bunsen
Chances are you will have used google today …. and chances are you will have seen the traditional google logo replaced with a bunsen burner, kettle, test tubes and so on.
Somehow (and I am still trying to figure out how to do this!) you can get the ‘google bunsen logo’ to turn into an animation, as the following youtube clip shows.

Molecular pistons and redox
A redox reaction has been used to move a molecular piston back and forth. It is hoped that this will allow nanomachines to make use of it.
The piston works with a man made molecule called a rotaxne. The rotaxne is a liner molecule with a napthalene complex at one end and sulfur containing group at the other end. The sliding part of the piston is made of six carbon rings, joined to form a hooped shaped positively charged ion.

Combustion kept simple
When teaching about combustion, we must remember to consider ‘complete’ and ‘incomplete’ combustion.
During complete combustion, the fuel will produce CO2 and H2O.

Mars mix up and data quality
Do you trust the temperature reading on your thermometer? How important is it to us that equipment records the ‘correct data’?
You may remember a few years ago (six and a half) that NASA landed a couple of robots on Mars – Opportunity and Spirit.

Water (5)
Tuesday was World Water Day 2011 and the theme for this year was ‘Water for Cities’. The theme for this weeks blogs posts will therefore be all about water.
So far, we have been focusing on the fact that water has a much higher boiling point than is predicted and that the reason could be pinned down to electronegativity.

Water, dihydrogen monoxide, oxy-dihydride – what ever you call it, it means the same thing – water (H2O). Water is special to us for all sorts of reasons …

Science meets TOK
Below is a good video from the BBC TV series ‘Horizon’.
I would recommend using it in a TOK lesson as it links in some good arguments and deals with the use of the scientific method.
