For PE my kid's school is taking them swimming once a week. At the indoor pool. On Monday kiddo slipped on some ice slush and fell on their arm so they couldn't participate in Tuesday's swimming. So they sat at the sidelines with their bookbag with an Airvalent.
The peak at 11:15 is the bus ride to the pool. I think 11:30 and 11:45 and 11:50 is when the teacher had everyone sitting together to explain something. You can see that at 12:25 kiddo left the building to walk home.
