Students explore how compass and Gauss meter detect a magnetic field. For this physics lesson, students build their own Gauss meter and sensor based on given procedure. They cite real world applications of magnetism.

Students investigate the magnitude of Earth's magnetic field using PASCO. In this physics lesson, students describe the features of the magnetosphere. They explain how atmosphere layers protect the Earth.

Third graders solve a cryptogram by decoding a message written with wingdings.  In this decoding activity, 3rd graders solve a message related to magnetism.  Students have notes about magnets once they've finished.
