今天科学课上,陈老师让我们做了一个小实验。首先,我们把抹布放在水中浸湿,平铺在桌子上。接着,把易拉罐放在抹布上。这时钟煜打开保温瓶,用勺子把冰块放到易拉罐里。放大半罐就够了。我打开放盐的袋子,用勺子把盐均匀地撒到冰块上面。接下来,把温度计从盒子中抽出来,插在冰块 Today's science class, Chen let us do a little experiment. First, we wet the rags in water and tiled on the table. Next, put the cans on the rags. This time Yu opened the thermos flask and put the ice cubes into the cans with a spoon. Enough to enlarge the half tank. I opened the bag with salt and sprinkled the salt evenly over the ice with a spoon. Next, pull the thermometer out of the box and insert it in ice cubes
