Lesson 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.

Learning intentions:

Students will...

  • understand the difference between sea ice and land ice
  • 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
  • understand that simple science experiments can be used to demonstrate these differences clearly.
