Checkpoint Science 0846 — Practice Paper 2

Working: the Earth travels around the Sun once a year (giving us the seasons) and spins on its own axis once every 24 hours (giving us day and night). The Sun does not orbit the Earth.

Strand: Earth & space (0846 P2)

Framework LO: 5Pb3

Working: living things carry out life processes (they grow, feed, reproduce). Kangaroo, rat and seaweed are living. Rock and sand have never been alive.

Strand: Biology — living things (0846 P2)

Framework LO: 3Bh2

Working: solids keep their shape (butter, ice, chocolate); liquids flow and take the container’s shape (orange juice, water); steam is water as a gas.

Strand: Materials — states of matter (0846 P2)

Framework LO: 4Cs1

Working:

1. Ice warming to liquid water is melting.
2. Water cooling to 0 °C and turning solid is freezing.
3. Water boiling turns into steam (water vapour / gas).

Strand: Materials — changes of state (0846 P2)

Framework LO: 4Cs3

Working: a producer makes its own food (a green plant); a predator hunts other animals; prey is the animal that gets eaten.

Strand: Biology — food chains (0846 P2)

Framework LO: 6Be5

Working: a consumer is a living thing that cannot make its own food, so it eats other living things. An animal that eats a plant is a consumer. (A green plant is a producer.)

Strand: Biology — food chains (0846 P2)

Framework LO: 6Be5

Working: light travels in straight lines.

1. An object blocking light makes a dark shape — a shadow.
2. A material you cannot see through at all is opaque.
3. A material that lets only some light through is translucent.

Strand: Physics — light & shadows (0846 P2)

Framework LO: 5Pl5

Working: the lowest number in the boiling-point column is 78 °C, which is liquid B.

Framework LO: 6Eo6

Working: pure water boils at 100 °C — that is liquid C.

Framework LO: 5Cs4

Working: she is changing the pot size, so everything else must stay the same — including keeping all the pots in the same warm place. (Using different-sized pots is the one thing she is testing, not a control.)

Strand: Scientific enquiry — fair testing (0846 P2)

Framework LO: 6Ep6

Working: he is saying what he thinks will happen before testing — that is a prediction. (A conclusion comes after the results.)

Strand: Scientific enquiry — enquiry vocabulary (0846 P2)

Framework LO: 6Ep4

Working: a balance measures mass; a thermometer measures temperature; a measuring cylinder measures the volume of a liquid.

Strand: Scientific enquiry — measuring equipment (0846 P2)

Framework LO: 6Eo1

Working: blood carries oxygen and nutrients (food) to the cells. It carries carbon dioxide away from the cells to the lungs to be removed.

Strand: Biology — blood circulation (0846 P2)

Framework LO: 6Bh3

Working: wires must let electricity flow through them easily, so the important property is being a good conductor of electricity. (Being shiny or hard does not help carry current.)

Strand: Materials — properties & uses (0846 P2)

Framework LO: 6Pm3

Working:

1. Sound is caused by vibrations.
2. A higher-pitched note comes from hitting a smaller key (it vibrates faster).
3. Foam is useful because it absorbs sound.

Strand: Physics — sound & pitch (0846 P2)

Framework LO: 4Ps4

Working: sugar dissolves and passes through the filter as a sugar solution. Chalk does not dissolve (it is insoluble), so it is trapped on the filter paper.

Strand: Materials — dissolving & filtering (0846 P2)

Framework LO: 6Cc4

Working: follow the arrows that point TO the owl — they come from the frog and the mouse. So the owl eats the frog and the mouse.

Strand: Biology — food webs (0846 P2)

Framework LO: 6Be6

Working: follow the arrows in the direction they point (energy flow). For the mouse: grass → mouse → owl.

Strand: Biology — food webs / chains (0846 P2)

Framework LO: 6Be3

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

Strand: Physics — light & shadows (0846 P2)
