What is weather?

The students watch as heated air sets a paper spiral in motion.

You will find the instruction in the Instruction tab.

After the demonstration, ask your students the following questions:
What did you observe?
Has the spiral started to rotate?
Why?
Do you know now how wind forms?

The students experiment and learn how clouds are formed. Together with your students, use balloons, bottles, and cold and hot water, and check the first element of cloud formation – through heating up, the air rises, and when it gets cooler, it falls down.

During the experiment, ask your students the following questions:
What do you observe?
What is happening to the balloons? Why?
In what way can we relate this experiment to cloud formation?
Where else can you observe this phenomenon? Do you remember the previous experiment?

With the help of hot water, ice and matches, the students will create clouds in jars and learn how water vapor from the air turns into a cloud and then into rain.

Did you see the cloud inside the jar?
