科学课上大家做实验的情景还历历在目,“热胀冷缩”的奇妙更是让我对自然界充满好奇。回顾让人不可思议的实验,我仍然激动万分。实验的材料十分有趣:一个熟鸡蛋、一个空奶瓶、一个盆子、一个矿泉水瓶、几个气球,还有热水和冷水各一袋。老师让我们在矿泉水瓶口套一个气球,然后将其浸在热水里,观察会发生什么奇特的事情。说干就干,我们小组以飞快的速度套好气球并将矿泉水瓶放到热水里。“啊!”我不禁尖叫起来,只见气球竟然在我将瓶子放到热水里的那一瞬间鼓了
The science lesson that we experiment with the scene is also vivid, “thermal expansion and contraction ” the wonderful is let me curious about nature. Looking back on the incredible experiment, I’m still very excited. The experimental material is very interesting: a cooked egg, an empty bottle, a basin, a mineral water bottle, a few balloons, and a bag of hot and cold water each. The teacher asked us to put a balloon in the mouth of a mineral water bottle and then dip it in hot water to observe what would happen strangely. To do it, our team set up the balloon at a fast pace and put the mineral water bottle in the hot water. “Ah! ” I can not help but scream, I saw the balloon even in the moment I put the bottle into the hot water drum
