Thurs/Fri: Review,problems, quiz, new date for exam

Thursday most classes finished the video on AC /DC and electric power/generation/history.  After the video, we discussed answers to homework problems and questions and corrected answers, and did independent review - some classes had time enough to look through some old test questions for Electricity.

Today we had a quiz covering several concepts in Electricity, from the basis of charge (the atom's components) to static electricity, charging, electric current, and electric power.  Grades were mixed, but most people felt comfortable with understanding why they missed what they did.
After the quiz, we started notes on Magnetism (get a copy here) and talked about safety with / care of magnets (not letting them fly together!).  Magnets are available on Monday for 50 cents apiece, and if you don't have money, you can stay after school on Monday to work on making lab equipment for Freeman and earn a Magnet Scholarship!  :)

Monday we'll continue with notes on Magnets, what they are, and how they interact, and everyone will have time to do some basic experimentation with their magnets.  We'll have a lab on Tuesday and Wed/Thurs (we have the PLAN test which will mean some classes will have a higher teacher:student ratio) and I am planning on moving the exam (due to the PLAN test) to Monday, 3/5.  If I can get it graded and into the gradebook on time, it will count for 3rd quarter grades, since it's over material you learned in 3rd quarter.
