Structured questions

Simple recall questions are usually worth 1 mark. They are often have command words like 'Give', 'State', 'Name' or 'Identify'. Some questions may ask you to state two things, rather than just one, and will be worth two marks.

Structured questions, with command words such as 'Describe' or 'Explain', will be worth two or more marks:

  • if you are asked to describe something, you need to give an account but no reason
  • if you are asked to explain something, you must give reasons or explanations

More complex structured questions will be worth three to five marks. They include questions with complex descriptions and explanations, questions in which you need to compare and contrast two different things, or calculations with several stages.

The mark schemes given here may show answers as bullet points. This is to show clearly how a mark can be obtained. However, it is important that your answer is written in a logical, linked way.

Sample question 1 - Foundation

Question

a) i) Describe how induced magnets are different from permanent magnets. [2 marks]

An un-magnetised iron bar is placed near a bar magnet.

A bar magnet in an angular 'U' sort of shape. The N and S poles are marked. There is a wire running through and round the magnet, with arrows indicating direction of current.

ii) Here are five statements about the above diagram, only two are correct, which two? [2 marks]

  • the bar is not magnetised
  • the magnet induces a N pole at the nearest end of the bar
  • the iron bar and magnet attract each other
  • like poles face each other
  • the magnet repels the iron bar

b) How can we show that the Earth has a magnetic field? What instrument would you use? [3 marks]

a) i) An induced magnet is temporary [1]. It is only magnetic when another magnetic field is present [1].

ii)

  • the magnet induces a N pole at the nearest end of the bar [1]
  • the iron bar and magnet attract each other [1]

b) A simple test is with a plotting compass [1]. If no magnetic field existed then a magnetic compass would not point to any specific direction on Earth [1]. But the compass needle would point to magnetic North in the Northern hemisphere and will point to the South Magnetic Pole in the Southern hemisphere [1].

Sample question 2 - Higher

Question

The diagram shows the shape of the magnetic field (as dashed lines) around a long straight wire. A current flows down the wire.

Wirecurrent

a) Describe how you would show the shape and direction of the magnetic field around the current in a long straight wire, including the apparatus you would use. [2 marks]

b) Describe the shape of the magnetic field lines around the wire. [1 mark]

c) The current is now reversed. State how this affects the magnetic field. [1 mark]

d) The current is now reversed. State how this affects the magnetic field. [1 mark]

e) State the two factors that affect the strength of the magnetic field near the wire. [2 marks]

Eduqas, GCE Combined Science, SAMs Component 3, 2016 - Foundation.

a) Sprinkle iron filings on the card [1] then follow the direction of a plotting compass around the circles to identify direction [1]

OR

Place plotting compasses at a number of places on the card [1] and mark where the compasses point to build up the picture [1]

b) Circles [1]

c) Direction reverse (but shape is unchanged) [1]

d) There is no field [1]

e) The distance of the point from the wire [1]

The current in the wire [1]
