Classifications of Basic Chemical Entities
This interactive activity attempts to explain the periodic table from a HIstorical Perspective. I believe this is a little weak. In fact the only weak part of the activity. Why, a key element that can be applied in a major way across the major sciences namely Biology, PHysics, and chemistry, is OXYGEN. There is a great story line in its' discovery. Namely the co-discovery of Lavoisier and Priestly. And, how the story of HOW they discovered it. However, the aspects of two interactive videos, followed interwoven with superior pictures, with some shown on an interesting chemical activity are superiior, and interesting. Within this activity can be found mumerous expample of good science. Example, the predictiion of future elements my early scitentists is excellent. Further, there are good questions for review, as well as constant inquiry questions for reflection, a summery, and quiz at the end. Finally, I thought the Point and click Glossary at the end should be included in all of my lesso
