In this lesson, students will simulate, observe, and manipulate the variables that affect electric field, electric line, like and unlike charges.

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

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

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 an electric field and electric field lines
• describe the interaction of like and unlike charges
• predict the motion of charged particles
