Week of December 3rd-December 7th, 2007
Fifth Grade will be working on Electromagnets
Electricity and magnetism are closely related. Magnetism is a result of electric currents, and electric currents can be produced by changing magnetic fields. When current flows through a wire a magnetic field is produced. An electromagnet's strength can be varied by varying the length of winding wire or the strength of the current.
This week fifth grade students will be building their own electromagnet out of a battery, insulated wire, and rubber band. Then, they will test the strength of their electromagnets using paper clips.
