Lessons Included

Video presentation on isotopes
~ Johnny3

I felt this video really helped my Chemistry classes understand what an isotope is and how the average atomic mass of one is calculated. The use of the tomato paste was brilliant; I may borrow that idea for my lecture/discussion on isotopes in the future. I'm really sold on the Sams/Bergmann team and hope to utilize their videos in future lessons.

Below are the descriptions for each of the lessons included in the series:
