北极圈和南极洲的冰块儿可以反射太阳光。全球温度升高会融化冰川和海冰,露出深色的海水和陆地面。这些区域会吸收热量。在这个实验中,预测和猜想这块冰会发生什么,写下来。完成实验,并制作一个数据表,记录时间、温度和融化的水量。你需要:一块冰切成两半,黑色塑料,锡箔纸,两个9cm深的容器,两支温度计,空胶带盒,两个150W~250W的台灯,两把椅子,尺子,计时器。第一步:在一个容器内放入一些锡箔纸,另一个容器中放入两层塑料。每个容器中放一块冰块儿。
Ice in the Arctic Circle and Antarctica can reflect sunlight. Global warming will melt glaciers and sea ice, revealing dark sea and land surfaces. These areas will absorb heat. In this experiment, what happened to predict and guess this ice, write down. Complete the experiment and create a datasheet that records time, temperature, and amount of water thawed. You need: a piece of ice cut in half, black plastic, foil paper, two 9cm deep containers, two thermometers, empty tape boxes, two 150W ~ 250W table lamps, two chairs, ruler, timer. Step one: put some foil in one container and two layers of plastic in the other. Put an ice cube in each container.
