This lesson aligns with the Common Core State Standards:
STANDARD 5 - Matter and Energy
"The teacher understands the nature and properties of energy in its various forms, and the processes by which energy is exchanged and/or transformed.
5A. understands the atomic and nuclear structure of matter and the relationship to chemical and physical properties
5C. understands the cause and effect of chemical reactions in natural and manufactured systems
5E. analyzes the properties of materials in relation to their chemical or physical structures and evaluate uses of the materials based on their properties
5F. explains conservation of mass and energy and explains interactions of energy with matter, including changes in state"
PowerPoint lesson I in the "Atomic Structure" unit III - introductory chemistry. This lesson explains how different atomic models have evolved through time; identifies evidence for atoms and the atomic nucleus; and describes the relative size of the nucleus compared to the entire atom.
A separate student PowerPoint worksheet for this lesson is also available.
PowerPoint lessons contain many graphics and links to short videos to further student understanding.
