Strand: Materials — reversible vs irreversible changes (0846)

Framework LO: 6Cc1

5 Paper 1 · Look at the circuit. The lamp does not light up. What is the reason?

The switch is open, so the circuit is not complete. The lamp is too bright. The wires are too short. There are too many cells.

Working: the switch is open, leaving a gap, so the circuit is not a complete loop. No current can flow, so the lamp stays off. Closing the switch would light it.

Strand: Physics — complete circuits (0846)

Framework LO: 6Pm4

6 Paper 1 · Look at the food chain. Which animal eats the grasshopper?

The frog The snake The grass The grasshopper eats nothing

Working: follow the arrows (they point from food to feeder): grass → grasshopper → frog. So the frog eats the grasshopper.

Strand: Biology — food chains (0846)

Framework LO: 6Be6

Strand: Physics — sound / volume (0846)

Framework LO: 4Ps1

9 Paper 1 · Lena measures the height of her plant. Explain why she should measure it several times and compare the results.

Marks: 1 points

Model answer: Measuring several times and comparing makes the results more reliable and lets her check the readings agree, so she can spot a measurement that went wrong.

Strand: Scientific enquiry — reliability (0846). Keyword auto-graded; model answer shown. ('more accurate' alone is not enough — repeating checks reliability.)

Framework LO: 6Eo2

10 Paper 1 · Maria tests which soil grows cress best. To make it a FAIR test, what must she do?

Give each pot the same amount of water and light, changing only the soil. Give each pot a different amount of water. Put each pot in a different place. Use a different type of seed in each pot.

Working: in a fair test you change only ONE thing (the soil) and keep everything else the same — so each pot must get the same amount of water and light.

Strand: Scientific enquiry — fair testing (0846)

Framework LO: 6Ep6

11 Paper 1 · Complete the sentences about the human skeleton.

Working: oxygen (part of the air) is a gas at room temperature. Water is a liquid, ice is a solid, and wood is a solid.

Strand: Materials — states of matter (0846)

Framework LO: 4Cs1

19 Paper 2 · Look at the food web. Which living thing is the producer?

The grass The owl The frog The mouse

Working: a producer is a green plant that makes its own food and starts the web. Here that is the grass — the arrows lead away from it to the animals that eat it.

Strand: Biology — food webs (0846)

Framework LO: 6Be4

20 Paper 2 · Look at the diagram. The object is moved further AWAY from the lamp. What happens to its shadow on the screen?

It gets smaller It gets bigger It disappears completely It changes colour

Working: the further the object is from the lamp, the less light it blocks, so the shadow on the screen gets smaller. (Moving it closer to the lamp would make the shadow bigger.)

Strand: Physics — light & shadows (0846)

Framework LO: 5Pl2

21 Paper 2 · Complete the sentences about dissolving.

When sugar is stirred into water, it .

The clear liquid you get is called a .

The clear mixture left is a solution.

Strand: Materials — dissolving & solutions (0846)

Framework LO: 6Cc5

22 Paper 2 · How could you separate sand from a mixture of sand and water?

Filtering Evaporating the water Freezing the mixture Adding more water

Working: sand does not dissolve, so pouring the mixture through filter paper traps the sand and lets the water through — this is filtering.

Strand: Materials — separating mixtures (0846)

Framework LO: 6Cc4

Paper 2 · Data: A growing bean plant

A class measured the height of a bean plant at the end of each week:

Week 1: 2 cm | Week 2: 5 cm | Week 3: 8 cm | Week 4: 11 cm

23 What happens to the height of the plant as the weeks go on?

It increases (gets taller) It decreases (gets shorter) It stays the same

Working: the height rises 2 → 5 → 8 → 11, so it increases — the plant is growing taller.

Strand: Scientific enquiry — describing a trend (0846)

Framework LO: 6Eo6

24 Paper 2 · What does the blood carry to all the cells in the body?

Oxygen and nutrients Only carbon dioxide Only water Nothing — blood just keeps us warm

Working: blood carries oxygen and nutrients (food) to the cells, and carries the waste gas carbon dioxide away.

Strand: Biology — blood circulation (0846)

Framework LO: 6Bh3

25 Paper 2 · A sycamore seed has 'wings'. How are its seeds most likely to be spread?

By the wind By floating on water By animals eating them By sticking to fur

Working: the wings make the seed spin and float on the air, so it is carried away by the wind.

Strand: Biology — seed dispersal (0846)

Framework LO: 5Bp3

26 Paper 2 · A parachute helps a skydiver fall slowly. Which force does the open parachute increase?

Air resistance Gravity Magnetism Friction with the ground

Working: the large parachute pushes against the air, increasing air resistance, which acts upwards against gravity and slows the fall.

Strand: Physics — forces / air resistance (0846)

Framework LO: 6Pf4

27 Paper 2 · What happens to the lamp if you add another cell (battery) to a simple circuit?

It gets brighter It gets dimmer It goes out It changes colour

32 Paper 2 · A polar bear has thick fur and a layer of fat under its skin. This mainly helps it to:

Keep warm in the cold Swim faster See in the dark Find food more easily

Working: thick fur and fat trap heat and stop it escaping, so they help the polar bear keep warm in its very cold habitat — an adaptation.

Strand: Biology — adaptation (0846)

Framework LO: 4Be1

33 Paper 2 · Through which of these does sound travel FASTEST?

A solid, such as metal A gas, such as air Empty space (a vacuum) Sound travels at the same speed through all of them

Working: the particles in a solid are packed closely together, so vibrations (sound) pass from one to the next most quickly. Sound is slowest in gases and cannot travel through empty space.

Strand: Physics — sound (0846)

Framework LO: 4Ps2

34 Paper 2 · Puddles slowly dry up on a warm, sunny day. What is this process called?

Evaporation Condensation Freezing Melting
