The Mosquito: Hoodie-repellent from the Valleys

A bit of fun for a sound/ hearing topic. the ASE has an activity about the high-pitched teenager-repellent noise that is being placed outside many public places to ward off antisocial behaviour. The device emits a sound that is only audible to those whose hearing remains completely intact, i.e. the under 25-ishes.

This clip from CNN UK could be used as an opener:

The activity centres around a radio or TV programme in which different points of view and ethical standpoints are addressed. “Hoodies have feelings too, you know!

If you want to test your hearing, get on a decent pair of headphones and check out the University of New South WalesEqual Loudness Contours and Audiometry activity.

Some more about sound after the jump.

The Matter with Antimatter

Big thanks to Alom Shaha, the Physics teacher behind, for posting this video about antimatter. A nice explanation and some visuals from the Tony Hart school of animation make it well worth a watch. Imagine what would happen if Morph collided with Antimorph

Why not go and have a look at the site for more clips on the big Bang and the beginning of it all.

The Theory of Everything?

Looks like the theory of etch-a-sketch*. I’m buggered if I understand it.

*or maybe Spirograph. Or that one with the colourful threads and the boards with holes in.

PhET Simulations

PhET have some good simulations on their website (Physics and Chem):

PhET Sims

Well worth trawling through to find some good ideas (like this skate-ramp) for the SMART board.

EDIT: this site’s helpfulness rating is boosted by the ‘run offline’ button next to  each sim – they actually want us to download these and use them for free. Rock on. Needs Java.
