Hi all - I'm Mr. Poser, a high school science teacher from rural Illinois, USA. My channel is designed with playlists to supplement learning in NGSS High School Life Sciences, Human Anatomy & Physiology, and AP Biology!

AP Biology videos are organized by topic according to the 2025-26 AP Biology Course & Exam Description, while Life Science/Biology videos are organized by unit and by NGSS High School Life Science Standards.
