Quick summary: In this activity students investigate what happens when rising temperatures cause ice on land and in the sea to melt. They conduct two experiments, one looking at sea ice and the other looking at land ice and observe how the melting of this ice affects the sea level.
This activity has been created in partnership with WWF-Australia. Earth Hour is the world’s largest community-driven climate change campaign. At the centre of Earth Hour is switching off lights to show a commitment to taking action. Thousands of teachers use Earth Hour’s education program to enrich their curriculum and provide pathways for young people to create change in their world.
Join the program and take part in Earth Hour Schools Day on Friday the 27th March 2020. You can also involve family and friends in Earth Hour on Saturday 28th March 2020 8:30-9:30pm.
- Students understand the difference between sea ice and land ice.
- Students recognise that melting land ice will affect sea levels, but that melting sea ice won’t cause as much of a rise in sea levels.
- Students understand that simple science experiments can be used to demonstrate these differences clearly.

Australian Curriculum content description:
Year 3 Science
- A change of state between solid and liquid can be caused by adding or removing heat (ACSSU046)
- With guidance, identify questions in familiar contexts that can be investigated scientifically and predict what might happen based on prior knowledge (ACSIS053)
- Compare results with predictions, suggesting possible reasons for findings (ACSIS215)
- Reflect on the investigation, including whether a test was fair or not (ACSIS058)
Year 4 Science
- With guidance, identify questions in familiar contexts that can be investigated scientifically and predict what might happen based on prior knowledge (ACSIS064)
- Compare results with predictions, suggesting possible reasons for findings (ACSIS216)
- Represent and communicate ideas and findings in a variety of ways such as diagrams, physical representations and simple reports (ACSIS071)
