32、 Revising and Editing There are many scientific principles in the world that can be tested by simple and interesting experiments. And today, I decided to do one named Magic bottle with the purpose of proving that the air pressure really exists. Revising and Editing Revising and Editing including a b

34、r. First of all, I removed the shell of the egg. Revising and Editing Revising and Editing So, the experiment proved that the air pressure indeed exists and it is really powerful. And at the same time, I observed carefully and recorded what happened. Reference version The experiment is designed to p
35、rove whether air pressure really exists. At the beginning of the experiment, I prepared the materials, including a boiled egg, a glass bottle whose neck is a bit smaller than the egg, and some hot water. With all the things prepared, the experiment began. Reference version First, I removed the shell
36、 of the egg. Then, I carefully poured some hot water into the bottle, and shook the bottle gently. After a few minutes, I poured out the hot water. Just at the same time, I quickly placed the egg on top of the bottle. To my amazement, the egg squeezed into the bottle at once. Reference version After
37、 the experiment, I can draw the conclusion that air pressure indeed exists, and it is very powerful. It is the force of the air that pushed the egg into the bottle. Homework Option 1. Students polish their experiment reports by imitating the example displayed in this class. Option 2. Students design and implement a new experiment and write a report of it.
