Students are given information and a diagram about a drink bottle overflowing when it had been put into the freezer. Students are asked to explain why this happened and how they could prevent it.
Plan an investigation to find out which of two students' predictions is correct, and identify how to recognise what a result would look like. Assessment focus: identifying what to measure or compare to answer a science question.
Using provided data students decide which of three liquids would freeze if placed in a freezer. Students explain what happens to particles when they freeze and how the level changes due to freezing.
Students are asked to explain how a stone from the top of a mountain could become sand on a beach. Students then identify the most likely way stones 'move' from the tops of mountains to the coast.
Students answer questions about the size of a balloon as the air temperature changes. The resource assesses students' understanding of the effect of temperature on gases.
Students use a diagram to answer questions about water reserves, the main difference between lake and sea water, and to explain how water in the ocean could end up falling as snow in the mountains.
Task: Predict, Observe, Explain, (POE) activity observing what happens to air in a balloon when it is heated. Assessment focus: behaviour of gases when heated and cooled.
Task: Make observations from a photograph, identify potential environmental problems giving reasons, decide which problem is the most important, and give reasons for the choice. Assessment focus: (1) observation, and (2) identifying and prioritising cause and effect relationships.
