你需要:三个有盖子的罐子,三个在醋里浸泡过24小时的生鸡蛋,线,直尺,蒸馏水,盐,糖浆或糖蜜,蜡笔,冰箱,科学笔记本,铅笔。第一步:首先,记录每一个鸡蛋被醋浸泡前和浸泡后的最大周长,将测量结果写在科学笔记本上。用线和直尺测量,确保精确,必要的话可以使用分数,然后往每个罐子里放入一个鸡蛋。第二步:将1号罐注满蒸馏水。第三步:将2号罐注满盐水。(盐和水的比例是1:10)第四步:将3号罐注满糖浆或糖蜜。第五步:用盖子把三个罐子盖好,在冰箱里放置24小时。预测每个罐子将会发生什么变化,把预测结果写在科学笔记本上。
You need: three covered jars, three raw eggs, straws, straws, distilled water, salt, syrup or molasses, crayons, freezers, science notebooks and pencils soaked in vinegar for 24 hours. The first step: First, record the maximum perimeter of each egg before being soaked in vinegar and soaked in vinegar, and write the measurement results on a scientific notebook. Measure with line and ruler to ensure accuracy, use fraction if necessary, then place an egg in each jar. Step two: the No. 1 tank filled with distilled water. The third step: the No. 2 tank filled with salt water. (The ratio of salt to water is 1:10.) Step 4: Fill tank # 3 with syrup or molasses. Step 5: Cover the three cans with the lid and leave in the fridge for 24 hours. Predict what will happen to each jar and put the predictions on a science notebook.
