here’s one that actually works in school…(link)

you should see a little animation here. it’s what’s going on inside the alveoli in your lungs. oxygen and carbon dioxide are being exchanged across the thin walls of the alveoli.

try this (activity 10 simulation). get the ball (choose carefully!) around the maze – see how fast you can do it

this flash demo proves that sound is faster in solids. you can adjust the distance (try 10000m then click on the hammer). use in unit 8l.

here’s a flash oscilloscope for showing sound waves. this one actually works properly! use it in unit 8l (sound and hearing).

instructions:
press ’start’ button
turn cro on with the red power button
drag any cable from the bottom to ch 1
adjust amplitude by adjusting voltage.
you can overlay displays by adding another cable to ch 2.

here’s a projectable simulation of the classic bell in a vacuum demo. open the tap to let air particles in, then suck them out using the pump. remember to have your speakers on to hear the sound change.

try this photosynthesis animation for pupil revision or for teachers on your white board.

try this flash for revision. it helps you understand (a) what goes in, (b) what happens inside and (c) all the equations.

here are some .swf files to try:
teachers: use them on your white boards
pupils: challenge yourself to explain what is happening

click the links to activate, they should open up in your browser.

gaddas, pooley are these any good? are they useful?
