Hi, next year i'll be teaching OCR Gateway physics, having previously only taught AQA. I've not got a problem with the content, but the equipment is proving to be a nightmare! We bought the resources packs for the units, so we have the student activity sheets and accompanying teacher/technician sheets. However, we don't have any of the necessary electronic equipment for P6 - all we have are some wires, bulbs, power packs, ammeters and voltmeters. I've been spending a while looking through equipment catalogues and there seem to be hundreds of types of thermistors, LDRs and diodes, but all that the specification says is "thermistor" - not very helpful! I'm the only physicist in the department and there's no-one else to ask about this at my school - I was wondering if anyone could help point me in the right direction for the types of components that I'll need if you've already taught this unit?
