One and two mark questions
One to two mark questions will start with command words such as 'describe' or 'explain'. Some command words are easy to understand such as:
- 'calculate' or 'determine' for maths questions
- 'complete' to fill in a gap in a table or graph
- 'state what is meant by' to give the meaning of an important term
- 'comment on' where you use your knowledge in an unfamiliar situation
The command words 'describe' and 'explain' can be confusing. If you are asked to describe a graph, you will be expected to write about its overall shape, whether it is linear or curved, the slope of gradients etc. If you are asked to explain why a pattern or trend is seen in a graph, you will be expected to use your science knowledge, not just say what you see (which is a description), eg 'The graph shows a steep linear increase for the first three hours because鈥'.
Explain how and why questions often have the word 'because' in their answer. Describe questions don't.
The number of marks per question part is given in this form: '[2 marks]'. It is essential that you give two different answers if a question is worth two marks. Sometimes you can gain a second mark by giving the units in a calculation or stating specific data points, eg the speed of the object decreased by 8 m/s.

Sample question 1 - Foundation and Higher
Question
A picture in the student's textbook shows two fishermen using a pole to carry some fish.
Fisherman A and fisherman B feel different forces on their shoulders. Use ideas about moments to explain why fisherman A feels the larger force. [2 marks]

The clockwise and anticlockwise moments must be equal. The fish are closer to A, so the force must be greater.
