Year 8 · Summer First Half
Physics
6 lessons from 2 units.
Unit P7 · lessons 4 to 7 of 7
Light crosses empty space at three hundred million metres a second and travels in straight lines. Follow one of those lines into a mirror, a block of glass, a pinhole, an eye and a prism.
Unit P8 · lessons 1 to 2 of 7
Put an ammeter either side of a bulb and both read the same. Follow that one fact from a torch to a junction, a voltmeter, an ohm and a cable that is copper inside and plastic outside.
- 04Lenses and imagesModelA hole in a box makes a picture, and it makes a bad bargain doing it: sharp or bright, never both. A lens is the piece of glass that refuses the bargain.Open this lesson
- 05The eye and the cameraSystemTwo instruments, built four hundred million years apart by completely different processes, and they have the same five parts doing the same five jobs. That is not a coincidence — it is what the physics of light leaves you.Open this lesson
- 06Colour and the spectrumModelA plain, colourless block of glass turns a beam of sunlight into a band of colours. What is the glass really doing to the light?Open this lesson
- 07Why things look colouredContrastA red jumper, a white shirt and a green bag look different in a room lit by one coloured lamp. What decides the colour you see?Open this lesson
- 01Current and circuitsModelPut an ammeter in front of the bulb and behind it. Both read exactly the same. Whatever the bulb is doing, it is not using up the thing that flows.Open this lesson
- 02Series and parallelContrastTwo bulbs, one battery, two ways to join them up. One arrangement dims both bulbs and fails completely if either one goes. The other keeps them bright and survives.Open this lesson
