Interactives (Online activities for student interaction & practice with content):

• Electric Field Simulation (Play ball! Add charges to the Field of Dreams and see how they react to the electric field. Turn on a background electric field and adjust the direction and magnitude)
• Electric Field Lines (A source of charge creates an electric field that permeates the space that surrounds. The use of lines of force or electric field lines are often used to visually depict this electric field. This Interactive allows learners to simply drag charges – either positive or negative – and observe the electric field lines formed by the configuration of charges)
• Conductors & Charge Distribution (students read about what a conductor is and how charge is distributed on various conductors)
• Virtual Van de Graaff Generator (Plug in this conductor & see how it works!)
• Lightning Rods (students explore the cause and mechanism associated with lightning strikes and read about how lightning rods serve to protect buildings from the devastating effects of a lightning strike)
• Capacitor Simulation (students explore how a capacitor works! Change the size of the plates and add a dielectric to see how it affects capacitance. Change the voltage and see charges built up on the plates. Shows the electric field in the capacitor. Measure voltage and electric field)

Games (Online games for students to apply & test their content knowledge):

• Put the Charge in the Goal! (students use the concept of electric fields to guide a puck around obstacles to a goal!)
• Electric Field Hockey (Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck’s motion. Make the game harder by placing walls in front of the goal)
• Electrostatics Video Game (The Electrostatic Video Game is a simulation consisting of one charge that is free to move and two charges that are fixed at specific locations. Using the principles of Coulomb’s Law, Pauli repulsion at close distances, and damping proportional to velocity, the objective of the game is to steer the moving charge around the maze to the exit in the lower right wall. This is accomplished by dynamically (in real time) changing the value of the charge on the moving particle in response to the forces acting on it due to the local electric field. By thinking about the the charges involved, and resulting fields, you should be able devise a strategy for guiding the particle to the exit)
