Yesterday, our gifted third graders experimented to see if land ice or sea ice causes higher sea-level rise. Using bricks(land) and blocks of ice, they discovered that melting land ice (glaciers) drastically raises water levels, while sea ice has a minimal impact. It was an eye-opening, hands-on lesson on climate change!
Key Findings:
- Land Ice: Increased water levels significantly.
- Sea Ice: Caused very little change in water level.
Steps:
1. We placed a brick in each container.
2. We then placed a block of ice ON the brick in one container, and then placed the ice on the floor of the plastic container in the other one.
3. Next we filled both plastic containers to the same level of water. We measured and drew a black line to make sure we were filling each container to exactly the same levels.
4. We then took the containers outside and waited for the sun to do its thing.
5. Seeing the results in class today was quite surprising! Cool learning experience!
