Part 1
What safety rules are you supposed to follow in the lab
Read the instructions carefully and never play with the instruments and mials in the laboratory.
Hands-on time
Read the instructions and predict what the result of the experiment is.
What factors might influence the experiment

What happened to the egg Why
What does the experiment try to prove
It tries to prove that air pressure does exist!
The egg was squeezed into the bottle.
When the temeperature within the bottle cools down, the air pressurei in the bottle would be lower than that outside the bottle. As a result, the egg was pushed into the bottle.
While-writing
Part 2
Taking notes
Write an experiment report
Complete the boxes in activity 5 with the information in Activity 5 and our discussion. Do further research if necessary.
Language Features of Experiment Reports
Concise&Precise
Experiment report standards
The report doesn’t miss any detail of the experiment;
The report illustrates the experiment accurately and concisely;
The report doesn’t contain any spelling or grammatical mistakes.
Post-writing

First Draft
Reading and doing peer assessment
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.
…including a boiled egg which was not hot any more, a transparent glass bottle whose neck was a bit smaller than the egg and some hot water.
When everything was ready, the experiment began.
I removed the shell of…
I carefully poured some hot water…
I poured out the hot water.
First of all, I removed the shell of the egg.
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 prove 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.
First, I removed the shell 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.
After 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.
