Ice resources

This practical task requires students to describe to a partner their observations about an ice cube melting. Students then develop questions about what they observe.

This practical task assesses students' ability to record and graph data, and draw conclusions, as they conduct an experiment on the rate at which an ice cube melts in different temperatures.

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.

Describe methods for speeding up and slowing down melting of an ice cube using one of three provided objects, and explain why the methods would work. Assessment focus: planning an investigation.

For this practical task students make a prediction about which lot of ice will melt first. Then students record their observations and explain why one lot of ice melted faster than the other.

Task: Select which picture correctly shows an ice cube in a glass of water and select correct explanation. Assessment focus: density of ice.

Task: Describe what happens to ice in a glass of water, giving reasons, and explain where water forming on the outside of the glass comes from. Assessment focus: changes of state.
