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.
In 2017, WWF is celebrating 10 years of Earth Hour and 10 years of progress on changing climate change. Our actions on climate change will shape the future for our children. They know more about climate change than any other generation. And they have extraordinary views on what they want for their planet. You and your students can become a part of the movement and start to take action on climate change by visiting earthhour.org.au to register for Lights Out or find your local event. Take part and register for Earth Hour Schools Day on Friday the 24th March and don’t forget to switch off on Earth Hour, on Saturday 25th March 8:30-9:30pm. Switch off to #JoinTheFuture.
- 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)
