The following activities will allow students to learn about the phenomenon, and we will take the opportunity to do some activities related to the cold.


Goals

At the end of the activities, the student will be able to:
- say what caused this intense cold wave;
- find the low temperature records for his region and compare them with others of his choice;
- use Excel to make a broken line diagram;
- name expressions in popular language to talk about cold and bad weather;
- list the social, environmental and economic consequences of a cold snap.


Suggested Activities

ACTIVITY 1: Record cold weather?

Every time a cold snap hits us, we wonder if we have ever known worse ...
What are the cold records for the period in your region?
Some world records here ...
Records for Paris
Canadian city statistics (click on United States or International for other cities)
Use the weather data to make a broken line graph using software like Excel.
It is the pupils who will decide the parameters of the graph, which they will have to identify correctly. (For example, records per day, per week or per month, for a given period, etc.)

ACTIVITY 2: A duck cold!

It is well known that many people like to talk about the weather! Moreover, many expressions color our language when it comes to it.
Brainstorm with the students the topic of expressions related to cold.
Some ideas to get started ...
- It's fret.
- Make a duck cold.
-…
Do your students like the activity? Extend by adding the theme of "bad weather"!
- He sells the bark of the oxen.
-…
If you have the opportunity to enter into communication with an overseas class, take the opportunity to discuss the expressions found on both sides in order to validate whether they are also used by your correspondents.
