Updated PowerPoint – I have just updated Gary’s PowerPoint to include the new IoP logo and the Stimulating Physics logo. I’ve also changed MUTR to Mindsetsonline and removed the reference to the price of eggs (no longer 79p!). I’ve not yet checked the other websites etc mentioned, but wanted to upload it here for anyone else to use, should you wish to.
Also, here’s the simulation of an eclipsing binary that I used (one to demonstrate the effect, and one to use in the practical) and the worksheet I gave my pupils when I did it with them. The worksheet is written for measuring the changing resistance, but I’ve also done it with a cell in the circuit, and measured the changing current, which drops during the eclipse, just as the light curve does, whearas the resistance increases, which may wrong-foot some pupils.
