This strand is unique to Cambridge. It tests how you set up experiments, identify variables (independent, dependent, controlled), and critique methods. 0893 Science Past Papers
Past paper clue: "Evaluate this experiment" or "Suggest one improvement"—these require you to spot errors in reliability or accuracy.
The mark scheme is arguably more important than the question paper. 0893 Science Past Papers often include mark schemes that show you exactly where marks are awarded. For example:
Without the mark scheme, you lose marks despite knowing the general idea. Past paper clue: Questions about filtration or distillation
Question 5: Forces and Motion A car travels along a straight road.
(i) Calculate the speed of the car. Use the formula: $Speed = \fracDistanceTime$. [2]
(ii) The driver applies the brakes. Describe the effect of the friction force on the car. [1] This strand is unique to Cambridge
