MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.
MS-PS2-5. Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.
Objectives
· 1. Students will analyze and evaluate evidence about magnetic force and determine that some evidence is not convincing because it does not isolate variables, by completing the Evidence Evaluation Handout, and mandatory question 10 with a 3 or better according to the rubric.
1. Do Now: Magnetism Pre-Quiz
2. Stations

Optional (ONLY AFTER YOU ARE FINISHED!!!!)
1. Play with this PhEt simulation to explore how to create electric and magnetic fields
2. Watch THIS MYTHBUSTERS EPISODE that tests whether or not an electromagnet can deflect bullets.
3. Watch THIS DOCUMENTARY about how magnets work
4. Play the roller coaster building game
