What? Open-ended game-like simulations with an intuitive interface and minimal text appropriate for a variety of class settings. Includes expert visual models that make the invisible visible and provide multiple representations, enabling scientist-like exploration and real-world connections.
Why? They are free and easy to incorporate into nearly any teaching environment or style. They are based on research into how students learn in general, student understanding of specific science concepts, and user interface design. Effective use of PhET simulations can lead to improved conceptual learning over traditional lectures, demonstrations, and labs.
Why not? PhET simulations might not be the best approach if your goal is for your students to learn to use real lab equipment or to learn to program, or if you don't have access to computers.
Here is an example of how to incorporate PhET simulations into an introductory physics class:
(IC In Class Activity; CQ clicker questions; HW homework; Demo: teacher centered group discussion)
Unit 1: Introduction to Motion:
Moving Man: IC/CQ
Unit 2: More on motion and Measurement
Vector Addition: IC/CQ
Unit 3: Forces and the Laws of Motion Publishing skills: curve fit, drawing, tables
Forces and Motion: Two activities IC/CQ
Unit 4: Work, Energy, Momentum and Collisions
Energy Skate Park: Four activities IC/CQ
Unit 5: Circular Motion and Semester Project
Unit 1: Heat and Thermodynamics
Unit 2: Waves: Introduction to light and sound
Waves on a String: IC/CQ
Unit 3: Electric and Magnetic Forces and Fields
Faraday’s Electromagnet Lab: IC/CQ
Unit 4: Fluid Mechanics, Semester Projects
Unit 5: Current, Resistance, Circuits, and Circuit Elements
Charges and Fields: Demo

You can find over 100 simulations available for free on the PhET website.
PhET also has an activity database where PhET team members and teachers from around the world can contribute teaching activities using PhET simulations. The database contains hundreds of activities that you can download for free, including labs, homework assignments, lectures, activities, concept questions, and more.
