Introduction

The PET curriculum is designed around the common theme of interactions.
Students learn to describe interactions in terms of either energy or forces.
The main themes are conservation of energy and Newton's laws. PET includes
the following chapters:

Chapter 1: Interactions and Energy
Chapter 2: Interactions and Forces
Chapter 3: Interactions and Systems
Chapter 4: Model of Magnetism
Chapter 5: Electric Circuit Interactions
Chapter 6: Light Interactions

The PSET curriculum is also designed around the common theme of
interactions. The main themes are conservation of energy, Newton's laws,
and small particle theory (including aspects of kinetic theory of matter and
atomic molecular theory). PSET includes the following chapters:

Chapter 1: Interactions and Energy
Chapter 2: Interactions and Forces
Chapter 3: Interactions and Systems
Chapter 4: Interactions and the Behavior of Gases
Chapter 5: Interactions and Physical Changes
Chapter 6: Interactions and Chemical Changes
