I'm a chemistry lecturer at 'Tycoch Tech'.
Some other contributors are beginning to arrive. Thanks!
We're still trying to get other teachers around the UK to add their bits. Wish us luck!
If you want anything added, but don't feel up to adding it yourself, you can e-mail me at e.mclaughlin [at] swancoll [dot] ac [dot] uk
