Teaching Tips

Ask students to watch the animation and ask them to try to pick out periods of time where ice loss was the greatest.

Animated images could be paused for discussion.

Note the difference between land-based ice sheets, which do elevate sea level when they melt, vs. ocean-based ice packs, which do not raise sea level when they melt.
