Physics
Electricity
how changing the number or type of components (e.g. batteries, bulbs/buzzers, wires) in a series circuit can make bulbs brighter or dimmer
compare and give reasons for the variations in how components work
how to represent series circuits by drawings and conventional symbols, and how to construct series circuits on the basis of drawings and diagrams using conventional symbols
Magnetism
about magnetic fields as regions of space where magnetic materials experience forces, and that like magnetic poles repel and unlike magnetic poles attract; magnetic fields by plotting with a compass; representation by field lines
Earth’s magnetism, compass and navigation
The behaviour of light
how light is reflected at plane surfaces
that light travels in a straight line at a finite speed in a uniform medium
light travelling in straight lines explains why shadows have the same shape as the objects that cast them
that non-luminous objects are seen because light scattered from them enters the eye
