Non-reschedule option: Email your professors and see if you can make up anything you missed after the trip and to check in with them to let them know you will be gone. They can also give you any work that you will miss so you can start working on some of them during the trip if you have time.
Reschedule option: Reschedule for next week when school starts to get settled in.
Either option works. Just make sure you let the professors know ahead of time. Hope this helps.
