Before you start to do anything, make a groupchat on teams.
You also add your teacher here.
This is the place where all the communication about the project takes place when you are not in a geography lesson. This way, the teacher can see how hard you are working and how the collaboration is going and if you have a good planning. This is also part of the assessment (see assessment).
We expect active participation from all group members. If you don't do anything during class, you will be put on absent.
Tip: you can call eachother in the groupschat if your working from home, that is a lot more effective than just chatting.
