•Explain that melting land ice adds to rising seas, while melting sea ice does not. •Observe and explain that warm water molecules expand, taking up more space. •List and consider some real-world solutions for sea level rise.
A practical experiment to investigate the effects of sea ice and land ice melting. To understand why melting land ice contributes to rising sea levels, whereas melting sea ice has no effect on sea levels.
•Explain that melting land ice adds to rising seas, while melting sea ice does not. •Explain that warm water molecules expand, taking up more space. •Discuss the impacts of sea level rise on the effects of storm surge.
How does melting sea ice affect sea levels? Experiment 1: See ice melting! For this experiment, we’re setting up an ocean environment, and using ice cubes to represent the Arctic sea ice. What you’ll need: • A clear glass or plastic container, like a baking dish or beaker • A jug of water (room temperature) • A tray of ice cubes
Melting ice sheets and glaciers on land add water to the sea. (See the “ What’s Causing Sea-Level Rise: Land Ice Vs. Sea Ice ” activity for more information about how melting ice contributes to sea level rise.)
EO Kids: Making and Melting Ice at Earth’s Poles.
Student Instructions Sheet. Graphing Sea Ice Extent in the Arctic & Antarctic. Large amounts of ice form in some seasons in the oceans near the North Pole and the South Pole (the Arctic Ocean and the Southern Ocean). This ice, which forms when seawater freezes, is called sea ice.
