1 Concepts Assessed Magnetism is a force that exerts a push or pull. Like poles of a magnet repel. Opposite poles of a magnet attract. A compass is an instrument that uses a freely moving magnetic needle to indicate direction. Static electricity is a build up of charge that can be released. A closed circuit is needed to light a bulb in a circuit. Switches open and close circuits. Metals conduct electricity. Electricity can be changed into heat, light, sound, or motion. Time 45 minutes Materials Advance preparation Individual Prompt 1. Duplicate the Pre-Assessment for each student Procedure: 1. Explain that this assessment is to help the teacher and the students tell what they know about magnetism and electricity. Explain that they will probably not be able to answer all the questions, but to try to do their best. 2. Explain that you will use the information from this assessment to help determine how best to help students learn more about magnetism and electricity. 4.A Pre-Assessment 1
