Year 4 Science Home Learning – 13.01.21

Today in science you are going to be electrical engineers, you are going to find and tell me how to solve issues with my circuits as I have got a little confused when making them. I have created a video below to explain the learning.

UPLOAD HERE

BRONZE

Explain which circuits will work and which ones will not work. Explain your answers.

SILVER

Explain which circuit will work and which ones will not work and how you know.

GOLD

Watch the video below and explain any mistakes I have made in making my circuits.

  1. Bronze:

    Only A will work because B isn’t connected at both ends and C isn’t connected properly.

    Silver:

    Only B will work. A is missing a wire and C hasn’t got a cell only 2 bulbs.

    Gold:

    The first circuit is missing a cell and the buzzer needs to be connected on both sides.

    The next ones needs to wires on both sides of the battery and the switch to make the light work.

    The yellow wire needs to be connected to the black wire on the buzzer for the last one.

    • Well done for checking the blog and giving this task a try Shuqraan.
      Why do you think that circuit will work and c will not work?
      Please can you make sure you complete Maths and English. Please also complete Mrs Sander’s phonics blog.

  2. bronze:
    1.circuit a will work because it is connected properly.
    2.circuit B will not work because both wires are connected to the positive side of the battery.
    3.circuit C will not work because the wire is not connected to the light bulb.
    silver:
    circuit A will not work because the wires are not connected.
    circuit B will work because it is connected properly.
    circuit C will not work because it doesn’t any batteries.
    gold:
    the first circuit doesn’t have batteries.
    the second circuit will not work because both wires are connected on the same side of the battery.
    in the third circuit the yellow wire needs to be connected to the black wire of the buzzer.

  3. BRONZE

    Explain which circuits will work and which ones will not work. Explain your answers.
    B and C wont work because for c the wires are not connected and for b the wires are connected to one side of the battery so current wont flow. So A will work.

    SILVER

    Explain which circuit will work and which ones will not work and how you know.
    A and C wont work because for a the wires are not connected. C wont work because it doesn’t have a battery. So B will work.

    GOLD

    Watch the video below and explain any mistakes you spot.
    A. a will not work because it does not have a battery.
    B. b will not work because both wires are connected to the same side of the battery.
    C. c will not work because the black wire needs to be connected with the yellow wire.

    • Excellent Sadeen!
      You have understood this task and completed today’s Science home learning to a high quality standard, well done!
      Your next step:
      Can you explain why a battery is needed in a circuit? Why is it important?

  4. Starter:
    1. The bulb won’t light with both wires connected the positive side of the battery because the electrons won’t flow properly.
    Bronze:
    1. Circuit A will work because circuit B’s wires are both connected to the positive side of a battery so the electrons won’t flow properly and one of circuit C’s wires doesn’t connect to the light bulb.
    Silver:
    1. Circuit B will work because one of circuit A’s wires doesn’t connect to the light bulb and circuit C doesn’t have any batteries.
    Gold:
    A. The first circuit won’t work because there needs to be a battery.
    B. The second circuit won’t work because both wires are on the same side of the battery so the electrons won’t flow properly.
    C. The third circuit won’t work because the yellow wire needs to be connected to the black wire of the buzzer.

  5. Bronze:
    A is correct because both wires are connected to the battery B and C not correct because B has both wires connected at the same place and C has one wire connected and the other not.
    Silver:
    B is correct because both wires are connected to the battery and C and A are not correct.A has 1 wire connected and the other not. C has no battery so it cannot light up
    Gold:
    A It does not work because it does not have a battery

  6. Bronze
    A is correct because the wires are connected to both sides of the battery and the light bulb .
    B is incorrect because both wires have to be connected to both sides of the battery and the light bulb to work.
    C is incorrect because both wires have to be connected to both sides of the battery and the light bulb to work.

    Silver

    B is correct because the wires are connected to both sides of the battery and the light bulb.
    A is incorrect because both wires have to be connected to both sides of the battery and the light bulb to work.
    C is incorrect because both wires have to be connected to both sides of the battery and the light bulb to work

    Gold
    A, B and C will not work.
    A: Because there is not a battery to power the circuit
    B: Because the wires are on the + positive side of the battery and not the – negative side of the battery.
    C: Because it has no light bulb to light up.
