Section C. A longer question (5 marks)

Each part uses what you found before. Show your working.

Question 205 marks

Lucía builds a loop with a cell, a bulb and two switches. From the cell, a wire goes to switch P. From switch P, a wire goes to the bulb. From the bulb, a wire goes to switch Q. From switch Q, a wire goes back to the cell. Use only a torch cell, never the mains.

(a)Switch P is closed. Switch Q is open. What does the bulb do? [1 mark]

(b)Lucía closes both switches. The bulb still stays dark. She looks at the cell. Both wires touch its knob end. Nothing touches the flat end. Why is the bulb dark? How should she fix it? [2 marks]

(c)Lucía fixes it, and the bulb lights. Next she makes a loop with one cell and two bulbs. The bulbs are the same kind. Both bulbs light, and they are equally dim. Her brother says the first bulb uses up some electricity. Is he right? Explain why. [2 marks]

Mark scheme

One line is one mark. A right final answer with no working gets every mark for that part. Lost marks? Read the chapter named under the part.

Question 11 mark

Answer: C. The wind carries it

  1. Maize is a grass. Grasses use the wind to carry their pollen.

Tests S2.1.6 Flowers and pollination

Question 21 mark

Answer: A. The bean plant has died. The mango tree has no flowers yet.

  1. A bean plant makes seeds in a few months, then dies. A mango tree may take five years or more to flower.

Tests S2.1.8 The life cycle of a plant

Question 31 mark

Answer: D. Bird

  1. The bird eats the caterpillar. The cat eats the bird.

Tests S2.2.7 Food chains

Question 41 mark

Answer: B. Omnivore

Question 51 mark

Answer: D. In a closed box, in the shade

Answer: C. Move further away from the loudspeaker

  1. Loud noise can harm hearing with no pain. Moving away protects her ears.

Tests S2.7.8 Noise and our ears

Question 142 marks

Answer: 52 beats

  1. Finds 31 − 18 = 13 more beats in 15 seconds, or finds both pulses in a minute: 18 × 4 = 72 and 31 × 4 = 124.
  2. There are four 15 second parts in a minute: 13 × 4 = 52 beats, or 124 − 72 = 52 beats.

Tests S2.3.7 Exercise and rest

Question 152 marks

Answer: 13 N

  1. The stones weigh 5 × 2 = 10 N. With the boat the weight is 3 + 10 = 13 N.
  2. The boat floats, so the upthrust matches its weight: 13 N.

Tests S2.5.7 Floating and sinking

Question 162 marks

Answer: 20 cm

  1. The wall is 8 steps away and the leaf is 2 steps away. 8 ÷ 2 = 4, so the shadow is 4 times as wide.
  2. 5 × 4 = 20 cm.

Tests S2.6.5 Big and small shadows

Question 172 marks

Answer: The whistle makes the air shake. The shaking air goes down his ear canal and makes his eardrum vibrate. The eardrum shakes three tiny bones, which pass the shake to the inner ear. The inner ear sends messages along a nerve to his brain.

  1. Says the shaking air goes down the ear canal and makes the eardrum vibrate.
  2. Says the shake passes on to the inner ear, which sends messages along a nerve to the brain.

Tests S2.3.6 A balanced diet

Question 205 marks

(a)Answer: B. It stays dark, because switch Q leaves a gap

  1. The parts are in one loop. The open switch Q leaves a gap, so the bulb stays dark.

Tests S2.8.8 Circuit drawings

(b)Answer: Electricity goes out of one end of the cell and must come back to the other end. Both wires are on the knob end, so the loop is not complete. She should move one wire to the flat end of the cell.

  1. Says electricity must go out of one end of the cell and come back to the other, so with both wires on the knob the loop is not complete.
  2. Says to move one wire to the flat end of the cell.

Tests S2.8.6 A simple circuit

(c)Answer: No. The same electricity goes all the way round the loop and back to the cell. The second bulb is just as bright as the first. If the first bulb used some up, the second would be dimmer.
