Practical questions
You will complete 21 required practical activities for GCSE Combined Science - Synergy.
There will be a number of different types of practical based questions. Some will be on the set required practicals, some will cover the working scientifically terms and some will be on other science practicals which you might have done in class. Use all the information given in the question particularly any diagrams to help you understand what the question is about.

Sample question 1 - Foundation
Question
A newtonmeter measures the weight of an object.
What is the weight of the object? [1 mark]
5.5 (N) [1]
Sample question 2 - Foundation
Question
Describe how you could find the magnetic field pattern of a permanent bar magnet. [3 marks]
Either:
- use iron filings [1]
- on a piece of paper [1]
- over the magnet [1]
or
- use (plotting) compasses [1]
- around the magnet [1]
- with the needle showing the direction [1]
Sample question 3 - Higher
Question
The image shows apparatus set up by a student.
Closing the switch creates a force that acts on the wire XY.
Explain why a force acts on the wire XY when the switch is closed. [3 marks]
Closing the switch makes a current through the wire [1].
The current flowing creates a magnetic field around the wire [1].
This field interacts with the permanent magnetic field [1].
Sample question 4 - Higher
Question
Below, the diagram shows apparatus set up by a student.
Closing the switch creates a force that acts on the wire XY.
State the effect that the experiment demonstrates. [1 mark]
Motor [1].
