I hadn't been out of high school for long when I wrote this. It's possible I was bitter... No, scratch that. I was DEFINITELY bitter. Look at the chalk board. Lesson plan? TYPES OF ROCKS. 

EARTH SCIENCE.

For the record? I did not do well in Earth Science. Also for the record? My teacher was positively awful at teaching. I'm not pulling any punches on this one. Just awful. If one were to buy a book on Earth Science, read it themselves while taking notes and occasionally watch a video, you'd have my old Earth Science class. I'm pretty sure we had more videos than actual lectures.

Occasionally, there'd be forgetable lab experiments, but for the most part the class was "read the book and teach yourself while copying info out of said books". Most of the time, you could have literally replaced the teacher with a brick and acheived the same level of education. I'm not going to claim I was a perfect student, because I wasn't, but good lord. A better teacher could have at least made the subject seem interesting.
