Middle School Lesson Plans

I am looking for a short story about a trip to a school lesson plan, grades 7-8. The trip can be physical, emotional, psychological, etc. The author should ideally be a minority (non-white men).

Thank you!

Jack London is still appropriate for the college ...

Although these authors are white, they have a lot of ethnic and write from personal experience
