Sample question 1 - Foundation and Higher

Question

An apple drops from the branch of a tree. It falls freely, then lands on the ground. Describe the energy changes and transfers that occur. [3 marks]

The apple initially has gravitational potential energy [1]. As it falls, the gpe is transformed into kinetic energy [1]. When the apple lands, the energy is transferred to the surroundings (heat and sound) [1].

Sample question 2 - Foundation and Higher

Question

A coffee shop sells coffee to take-away in polystyrene cups. Explain why polystyrene is a suitable material for take-away coffee cups. [3 marks]

This question has been written by a Bitesize consultant as a suggestion to the type of question that may appear in an exam paper.

Polystyrene is an insulator/poor conductor [1]. This reduces heat loss through the sides of the cup [1]. It keeps the coffee warm/reduces the chance of it burning the customer [1].
