In this lesson, students will use a simulation to observe and manipulate electric field, electric lines, positive and negative charges.

• Students will describe what happens when positive charges interact.
• Students will describe what happens when negative charges interact.
• Student will simulate the motion of a charged particle through an electric field using the properties of like and unlike charges.

• electric charge
• negative charge
• electric force
• positive charge
• electric field lines
• electric field

Adapted from a PhET^TM simulation, this lesson is a simulation of an electric field where positive and negative charges interact.  The fictitious context is of a hockey-style game where a positive charge (the "puck") is pushed through the "goal".

As a result, students will:

• describe the interactions of two positive charges, two negative charges, and a positive and negative charge
• predict the motion of charged particles
