The middle school I teach at is relatively small. Our entire middle school has less than 80 students. I'm the only science teacher in our building and I prep for 6th, 7th, and 8th grade. 6th Grade is a general science class, 7th grade is life science, and 8th grade is physical science. Having three different preps a day can be challenging, but it's nice to be able to switch things up throughout the day.
