I have done all the tasks for the school that we have already been given.
It's just good weather and don't want to gamble or watch Netflix.
Go jogging alone
Puzzle, read, paint, play games…
what you can do at home
So, first of all: You don't have a vacation, you have school-free time, that's something completely different…
Nobody basically forbids you to go out…
I don't want to do that when the weather is good
As long as you are not under quarantine, you can go outside. However, you should avoid social contacts, so that trips (alone) to the surroundings of your place of residence offer themselves. You can keep in touch with friends and acquaintances by mobile phone.
Then go out alone.
Jogging, doing other sports, going for a walk or just somewhere outside. Sit down. Or take photos or something.
What you want doesn't matter right now. Do you want to be infected or infect others… No.
