That's an opinion, but other than that are you trying to make a point or is this a question?
Hello principal (name),
I writing to you today to ask for you to organise a trip to the zoo. There are many learning opportunities for our class to go, from learning about the different animals and their living habitats. It would also make the kids feel more excited about school, since in a way it’s a hand on learning. (If you’re learning about animals in school right now, write about how it ties in with what your learning and how it can help the kids further understand the subject). As a class we promise to be on our best behaviour and hope that you at least take it into consideration. Also not to mention it’s a good way for everyone to spend the day, including yourself.
Best regards,
(Your name)
