I had my university observation happening at the same time with my university practicum professor, Dr. Ryan Cain. In the midst of that and with this exciting science lesson, there was a lot going on. I forgot to hit record on this until about slide 9. Also, I did not have permission to record the students faces, so the camera is pointed down. Normally I would hold the camera facing me, so at least you could see me, but I had to have my hands free for the experiment we were running. Thank you for your understanding!
