For this essay you need to look carefully at the size of the boat, its dimensions and weight, and then at the supplies that have been collected. You have learned about DENSITY and BUOYANCY from our labs and from reading in the textbook. Using what you have learned, what sort of PLAN can you come up with that will successfully lift the boat off the bottom of the lake and make it float so that it can be brought safely to shore?

Each student gets to respond ONE TIME to the question. You MUST write a one paragraph response. You need to be convincing and correctly provide at least 20 solid facts, measurements, and climate change vocabulary terms in order to land an "A" on the essay.
