Hi,
I was doing to research for our 10th grade Chemistry plans and came upon this PBS special called “Hunting the Elements”. I have watched about 20 minutes so far and it looks really interesting, fascinating. There is also a few teacher support items-video clips, Periodic Table poster, a lesson plan, an App. that lets the student build an element with the correct number of protons, neutrons, and electrons. I hope this link will work…..
