Re: [Phys-l] Challenge Activity

We used to keep a few three pole magnets around. Students were required
either to determine which of several magnets was different and how or to
do a field map of the three pole magnet.

Re: [Phys-l] Challenge Activity


My introductory physics courses does the "test for a magnet" activity. But
I may adapt something for the upper level course. And, yes,
characterizing the behavior of an unusual apparatus would certainly be in
line with what I'm looking for! Thanks for the input.

Perhaps a bit too easy: determine which of two identical, in
appearance, rods is the magnet. (poles, as usual, at the ends.)

Would characterizing the behavior of an unusual apparatus satisfy
your desire? [Preceded by a prediction.]

bc has a number of them. (vibrations)

Greetings Gang,

This term I'm trying to add some new elements to the Physics II lab
experience. I plan on covering two labs related to a section of
material then conducting a "challenge activity" during the next lab
period. For example, after covering circuits and resistance, the
challenge activity will be a black-box electric circuit that they
have to figure out the wiring diagram for based on the information
they obtained from their previous laboratory experiences. No
direct instructions will be given for the challenge beyond the goal
they are to accomplish. At the end of the lab period they will
submit a journal of their investigations along with a short write-
up of their conclusions. question...might anyone have an
idea for a challenge-type activity for vibrations, waves, & sound
and for magnetism? I have the one for circuits (as mentioned) and
one for light & optics but am at a loss for the other two topics.

Any assistance would be appreciated!

Regards, Robert.
