I had Ms. Stemmler a long time ago. The class was so horrible that I had to transfer to Mr. Lander's class. One day in class, I finished my work early. Instead of doing the prescribed word search (I have a visual processing disability), I read a science book. I got in trouble.

Mrs. Stemmler is by far one of the best teachers at Canyon along with Mr. Lawrence. Her class was fun and I learned a lot.

Awesome teacher, don't listen to the other kids, they didn't study. Homework is very easy, very little. Made me interested in life science, good discussions. Plays favorites, but it's harmless, doesn'

She's really nice if you are a good student. Mrs. Stemmler seems really into her subject, and it's nice to have a teacher like that. I learned a lot from already and it's only second quarter!
