“What’s the prognosis, Fertile Myrtle?”
“That ain’t no etch-a-sketch. This is one diddle that can’t be undid, Homeskillet.”
Probably the most realistic, sensitive and enjoyable movie about a teenage pregnancy ever made.

Freezeray.com – clicky-clicky!
This is a great resource for KS3 teachers. Thanks to Joshua Jones for posting the link to the TES Boards.
There is finally a site that aims to produce resources for classes AND deliberately allows them to be saved and kept for use on the IWB. They even have a page to help you save Flash files – and templates to make your own Flash tasks on Flash MX 2004 +.You know what’s even better? The Flash animations are actually useful. Such as this one, which is a simple and clear graph plotter for middle school. They also have technology (mehanics) sims, investigation planners and a bank of hangman-style keyword activities. Rock on.
It is produced by Freezeray, in association with Great Barr School – a specialist Science college that looks like it might actually be into Science.

Slideshare.net – upload slideshows and embed for free
Slideshare is a great service if you need somewhere to store slideshows online for free. you can upload powerpoints as shows or pdf files. Other programmes (e.g. mac) need to be uploaded as pdf.
Shows are then processed and can be embedded to blogs, wikis or webpages and, if you allow it, they can be downloaded by those who view them. They can be tagged and can also be viewed fullscreen online. It’s pretty much the YouTube of powerpoints.
Here’s an example (Photosynthesis* for IBDP Biology):
*edit – I had posted Cell Respiration, but deleted it by accident from the Slideshare account. Be careful – there’s no ‘are you sure?‘ box when you hit delete!
Cell Respiration – linklist
Here’s a good one for an opener: no narration, just an action-packed graphic.
It comes from Dr. Meyer at Queensborough Community College.

150 years since ‘On the Origin of Species’
Darwin’s theory of natural selection was finally published (and sold-out) in November 1859. The idea had been in his head, and a talking point of others, for years before. We’re still talking about it today.
Here’s a clip from a BBC documentary called Legacy about the impact of Darwin’s ideas:
The Guardian newspaper has a great page devoted to Darwin, including key excerpts from ‘On the Origin of Species…‘ and an article by Richard Dawkins.
You can download the full text of the first edition in pdf format from the University of New South Wales, or read it online at Talk Origins.
