5F. explains conservation of mass and energy and explains interactions of energy with matter, including changes in state"
Student note sheet to the PowerPoint lesson III in the "States of Matter" unit II - introductory chemistry. This lesson explains what happens to water molecules during phase changes; identifies phase changes as exothermic or endothermic, and describes the six common forms of phase change.
PowerPoint lessons contain many graphics and links to short videos to further student understanding.
PowerPoint slides also contain notes for the instructor based on students most "frequently asked questions" or FAQ's to help clarify the subject.
A class activity is included at the end of each lesson.
