My computer would not allow me to embed the video on my blog.  I needed to update my Java (which my computer would not allow).

The purpose of this screencast would be to give the students a visual as they are learning to identify atomic number and mass and what this translates to in an atom.  This would complement a lesson I have taught previously and showed them the skill.  They would be able to refer to this video for what they could not remember in class.
