The experiment shows us the effects of air pressure. Air pressure indeed exists, and it is very powerful. Activity 6 Complete the boxes with the information in Activity 5. Do further research if necessary. Introduce the aim of the experiment. This experiment is designed toto prove whether air pressure really exists. Describe the materials used in the experiment and explain the procedure. I prepared a boiled egg, a glass bottle (bottleneck a bit smaller than the egg) and hot water to do this experiment. Activity 6 Complete the boxes with the information in Activity 5. Do further research if necessary. Procedure: 1. Remove the shell of the egg. 2. Carefully pour some hot water into the bottle. 3. Shake the bottle gently. 4. Pour out the hot water. 5. Quickly put the egg on top of the bottle. 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. Activity 5 Read the instructions for the experiment and answer the questions. This fable describes… The fable teaches us that… One example of this from real life is… In conclusion, … Sample 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. The experiment is designed to prove whether air pressure really exists. Sample 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, l 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. Activity 1 Work in groups. Look at the pictures and discuss how these objects have changed over the years. Activity 2 Choose one of the objects in Activity 1 or an object that you use every day.
