The writing main points:
【答案】（possible answer:）
Your understanding of the saying Supporting details
As the old Chinese saying goes, “What you hear about may be false, but what you see is true.” We often easily believe what we see or hear with doubt,but as a matter of fact, it is not always so convincing. New research suggests that the story of Franklin’s experiment may be fiction instead of fact.
Some scientists questions the story about apple that fell on Newton’s head and led him to come up with his theory of gravity. In fact, there is no proof that the apple hit him on the head.
Personally, we can not be content with what we see or hear. As the old saying goes, “Practice is the sole criterion for testing truth.” What we see or hear is true or false remains to be seen in the future. Please don’t hesitate to taste what you see or hear.

Introduction Introduce the aim of the experiment.
Main body Describe the materials used in the experiment and explain the procedure.
Conclusion Report the results and what you have learned.

This experiment is designed to figure out why the boiled egg is swallowed by the hot glass
I prepared such materials as a boiled egg , a glass bottle (bottle-neck a bit smaller than the egg ) and hot water to do this experiment. Procedure: 1. Remove the shell of the egg. 2. Carefully pour some hot water into the bottle. 3. Shake the bottle gently. 4. Pour the hot water. 5. Quickly put the egg on top of the bottle.
After the experiment, I can draw the conclusion that it is true that a boiled egg can be swallowed by a hot glass bottle in the right experiment. Through this my own experience, I have learned that so long as we just study hard, observe and think carefully, we can figure out the secret of some scientific knowledge
