Helps pupils explore relationship between variables. Comparative tests children compare one event with another e.g. does the red car go faster than the green car? A fair test identifies the causal relationship between two variable. E.g. does the height of the ramp affect how quickly the toy car rolls down the ramp and everything else remains the same.
Across the year groups, there are lesson suggestions for developing the skill of Comparative & Fair testing from Year 1-11.
