Tuesday Mr. F. was absent; classes watched a video on magnetism and worked on a scientific method review worksheet (in addition to Monday's posted homework assignment).
Wednesday labs and homework were turned in, and we experimented with magnetic fields - showing where they are on a magnet, how they're shaped, and how they react to being in the presence of multiple magnets with iron filings inside glass jars and with some magnetic fluid - a knockoff of FerroFluid. We also tried to verify where the N and S poles of a magnet are using a compass, and figured out how a compass reacts when placed in various locations around a magnet (it lines up with the magnetic field lines we drew in our notes!)
Today we went over answers to the homework turned in on Wed. and answers to the scientific method review WS. If you had a disc magnet, you also got some fun toys to work with - the makings of a homopolar motor - another cool version here.
Tomorrow in class we'll share findings from the electromagnet lab, discuss graph types and lab grades (some of you aren't looking at past labs) and have a fun assessment of magnetism studies - a Jeopardy game. Classes who are uncooperative will earn a traditional quiz.
