On Monday, Lina placed two identical jars beside the school garden. She put a lid on one jar and left the other open. Both began with 200 ml of water. On Friday, the closed jar still held 200 ml, while the open jar held 170 ml. No rain fell that week. Lina wrote, “Water can leave an open container even when nobody pours it out.” Her friend suggested repeating the test in the shade. Lina agreed: one sunny week was not enough to know how shade might change the result.

3. What explanation for the loss is consistent with the passage?
Evaporation: liquid water changes into water vapour and leaves the open jar.
Award one mark for evaporation and one for explaining water leaving as vapour; the passage rules out pouring as the intended explanation.
4. Why does Lina agree to repeat the test in the shade?
They have not tested shade, so this result does not show what would happen there.
Award one mark for the untested shade condition and one for connecting it to the need for more evidence.

5. Write a conclusion supported by these results and one limitation.
In this test the open jar lost water while the closed jar did not. A single week and one pair of jars cannot establish the effect in all conditions.
Award one mark for the observed comparison and one for a justified limit; do not require this exact wording.
