(2nd hour does not have homework)
Homework for Monday: p. 450, #1-15, 23, 24, 26, 27
Freshmen Women interested in Engineering: Washington University's Catalysts For Change workshop is March 24 & 31; see the flyer in my classroom for more info or email them here to reserve a spot.
We will have a small quiz Monday on Magnetism and then we'll start our next unit (Energy in the atmosphere - Meteorology) I have decided to limit our studies in the remainder of the year to two other units after Meteorology - Astronomy and Waves. We'll also have some unofficial units that are smaller covering topics involved with geology, theoretical physics, fluid physics, and pre-Chemistry. These will not be tested in official units; material from these will appear only on quizzes, homework and your Cumulative exam which will be held right before the last days of school when "finals" are held.
Today in class: Magnetic Phenomena - is Copper magnetic / can it be made to be magnetic?
The main theme was answering this question, and "yes, kind of...." was the answer - Moving charges create magnetic fields, and moving charges within a magnetic field experience a magnetic force. Between these two ideas, we connected our knowledge and experience with electromagnets, magnetic fields, and motors to new phenomena: copper and zinc (pennies) being affected by magnets (only while in motion!) and copper pipes acting to slow the descent of magnets when dropped through them.
After that, we played Magnetism Jeopardy! A fun way to end a fun week with magnetism.
