  - Lesson 01 - Lesson Plan Lesson Title
    - Potential difference is the difference in energy between two parts of a circuit, and is measured in volts. - KS3.P.42
      - Suggested Activity:
        Measuring voltage and current in a series circuit
        Equipment Required:
        Electricity trolley
        voltmeter
        ammeter
        leads
        powerpacks
        batteries
    - Electric current is the flow of charge and is measured in amperes.
      
      KS4: Add 'rate of' to definition and then define the coulomb. - KS3.P.41
    - The charged particles able to move in a metal are electrons. So in a metal current is the flow of electrons. - KS3.P.41
    - Current is measured using an Ammeter which must be placed in series in the circuit. - KS3.P.41
    - Potential difference is measured using a Voltmeter which must be placed in parallel with a component. - KS3.P.42
    - Charge can not be created, destroyed or be stored on a wire, therefore currents add where branches meet. - KS3.P.41
    - Potential difference is a store of energy caused by the compressing of a charge particle's electric field. - KS3.P.42
    - Potential differences in series add up, for example adding cells - direction important. - KS3.P.42
    - Battery and bulb (p.d.) ratings need to be matched otherwise too much energy transfer will cause the bulbs to melt. - KS3.P.42
- 8P.02
  - Lesson 02 - Lesson Plan Lesson Title
    - Circuits are represented by circuit diagrams in which:
      - Wires are drawn as straight lines
      - With component symbols
      - Right angle corners. - KS3.P.41
      - Suggested Activity:
        Students make simple series circuit.
        Equipment Required:
        Bulbs
        Cells
        Connecting wires
        Switch
    - Component symbols to know
      - Cell
      - Battery
      - Wire
      - Bulb
      - Switch
      - Voltmeter
      - Ammeter - KS3.P.41
      - Suggested Activity:
        DEMO: Electrical components
        Equipment Required:
        Examples of components:
        Cell
        Battery
        Wire
        Bulb
        Switch
        Voltmeter
        Ammeter
    - Series circuits consist of only one branch with component placed one after another. - KS3.P.41
    - Parallel circuits consist of more than one branch. - KS3.P.41
- 8P.03
  - Lesson 03 - Lesson Plan Lesson Title
    - Resistance is a measure of how hard it is for current to flow through a material / set of components and measured in ohms, - KS3.P.42
      - Suggested Activity:
        Resistance across a copper wire
        Equipment Required:
        Powerpacks
        Large variable resistors
        ammeter
        voltmeter
        leads
    - The differences in resistance between conducting and insulating components can be explained by the amount of charged particles (and how much charge they hold) available to move.
      
      Conductors have more available charge carriers than insulators. - KS3.P.43
    - Resistance is the ratio of potential difference (p.d.) to current. - KS3.P.42
    - To be able to calculate Resistance given a p.d. and current using R = V / i - KS3.P.42
    - To be able to calculate either a p.d. or current given the other and the resistance by rearranging R = V / i - KS3.P.42
- 8P.04

    - Electromagnets enquiry:
      Aim: To find out how the __________ affects the strength of an electromagnet. - KS3.P.49
    - D: The motor effect occurs when a magnetic field created by a flow of current interacts with a magnetic field from a permanent magnet. - KS3.P.49
    - D: To use the motor effect to explain:
      - a 'ding dong' door bell.
      - Speaker - KS3.P.49
