AP Physics 2, Big Ideas 2 & 3, Investigation 9

For hundreds of years, explorers have used compasses as a means to navigate and discover our planet thanks to the presence of the Earth’s magnetic field. Migratory birds also use this field to navigate to more suitable climates. How does this field work? Why are some metals magnetic and not others? What is magnetism and what does this field look like?

This advanced-inquiry lab uses an activity-stations approach to guide students through an in-depth exploration of magnetic properties. Each of the four guided-inquiry activities are self-contained, focusing on a specific topic:
• Gravity vs Magnetism—Analyze the difference in magnitude between the forces of gravity and magnetism.
• Induced Fields—Construct a model of the magnetic field to illustrate the Right-Hand Rules and how magnetic fields are induced from electric currents in a wire.
• Magnetic Domains—Study iron filings in a test tube to gain an understanding of the abstract concept of a magnetic domain.
• Magnetic Field—Explore how compasses deflect in the presence of the Earth’s magnetic field and that of a permanent magnet.

Complete for 24 students working in pairs.

Performance Expectations

MS-PS1-3. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
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
HS-PS2-5. Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.
