All of the children at the Marienschule are currently dealing with the scientific topic of “air and air pressure”.
While the students in the lower grades deal with the properties of the air, the students in the higher grades investigate the question of the effect of air pressure. The starting point for this is the question “Does air have weight?”. Perhaps, at the end of the lesson series, they will also be able to explain what happens to a chocolate kiss in space.
In the first and second school year, the pupils are amazed, because a mug with a cloth is dipped with the open side into the water and the cloth stays dry. Or the submarine is pressed down by a cup, although it is not touched by the cup.
When the air is compressed, it is strong, even strong enough to carry a person, bounce a ball, or lift things. This is also amazing, especially since I cannot feel or see the air around me – unless the air is in motion and becomes the wind.
