This is an activity about electromagnetism. Learners will set up a simple circuit using a battery, wire, and knife switch, and then use a compass to map the magnetic field lines surrounding the wire. Next, they will add a coil of wire to the simple... (View More) circuit and map the magnetic fields again. This is the second lesson in the second session of the Exploring Magnetism teachers guide.

This is an activity about electromagnetism and the Sun. First, learners will do a KWL activity using six vocabulary words. Next, they will build an electromagnet and investigate how it works. Finally, learners will relate the workings of their... (View More) electromagnet to a Solar Dynamics Observatory magnetogram image of the Sun. Per group of learners, this activity requires materials such as a length of insulated wire, alligator clips, a 2-D-battery holder, two D-batteries, and a nail. (View Less)
