Diagnostic Questions for 11-14 Supporting Physics Teaching

What the Activity is for

The diagnostic questions can be used to check pupils' understanding of power.

What to Prepare

  • copies of these questions (see below)

What Happens During this Activity

The questions might be used for homework or as the basis for discussion in class.

Best word: is designed to check pupils' ability to use the correct terms in relation to a simple electric circuit.

  1. An electric current
  2. Electric charge
  3. Voltage
  4. Energy
  5. Power output

Make a match: probes understanding of three fundamental electrical units.

  1. 1 ampere is the same as 1 coulomb / second (2)
  2. 1 volt is the same as 1 joule / coulomb (4)
  3. 1 watt is the same as 1 joule / second (1)

Who do you agree with?: probes pupils' understanding of a series circuit with two bulbs of different rating.

  1. Tanya: agree
  2. Ben: disagree
  3. Jane: agree
