Melting Icebergs Experiment
The experiment we did in the lab “Melting Icebergs,” shows what would happen if the ice at the North Pole melted. The ice at the North Pole is floating on water so it has already displaced the volume of the ice in the ocean. If the ice melted, the oceans would not rise.
On the other hand, the ice at the South Pole covers
Antarctica. If that ice melts it will cause ocean levels to rise. Scientists believe that Antarctica is covered with about 90% of Earth’s ice which, if melted, could cause the oceans to rise about 200 feet. Since the average temperature in Antarctica is -37°, most scientists believe that this meltdown will not occur.
If I were doing this experiment with my students I would certainly expect them to spend time researching both sides of the global warming issue. Although most scientists agree that the atmosphere is warming, they do not all agree on the cause. A look at ancient climates might be valuable to determine how shifts in climate have occurred in the past.
The other question I would ask my students is, how can we perform a second experiment to model what would happen if the South Pole ice cap melted.
