Disciplinary Core Idea PS1B - Chemical Reactions

In this video Paul Andersen explains how chemical reactions progress as bonds are broken and reformed reformed. He explains the difference between changes in state and changes in molecules. He discussed collision theory and explains why increases in temperature and concentration can increase reaction rates. He also discusses the conservation of matter in chemical reactions. The video also contains a teaching progression for chemical reactions from grades K-12.
