Middle and high schoolers use the Pythagorean Theorem to complete a table showing with the magnetic field strengths in given cities. They find the average value of the Earth's magnetic field and plot one of the three-dimensional values...

Young scholars design a simple compass. They examine how the Earth's magnetic field has both horizontal and vertical components. They determine how a compass works and work with cardinal directions.

Students interpret magnetic field maps, rotate the coordinates to obtain different views, change the coordinate representation, and produce alternate graphical representations.
