Capacitance Lab
Posted by: Scott on: April 1, 2010
Marcie and I have been chatting. She has this capacitor lab that she likes and said I can post it here. The kids use the multimeter to measure the capacitance of some rudimentary parallel plate capacitors made from Al foil (Note: the Harbor Freight multimeters do not measure a small enough capacitance for this lab…it’s [...]
First Pass at Series & Parallel Circuits
Posted by: Scott on: April 20, 2009
This mini-lab worked out really well. In fact, quite of few kids surprised me by getting into building circuits. I know a lab goes well when nobody bails or gives up in frustration. I introduced series and parallel circuits with three quick overheads. I also taught them the schematic symbols for a battery, switch, and [...]
Lemon or Lime Battery

It’s not about being politically correct. Limes are cheaper than lemons. A bag of 5 limes was $1, lemons were $2. Since we were sticking metal in them and then throwing them away, frugality wins. Besides, I have some leftovers that may become margaritas. Now, I ran out of time and didn’t create a lab [...]

I do this more as an activity than anything else. I end up trying to cover electricity and magnetism in about two weeks, not anywhere near what is needed. I try to make the material relevant because it’s above most of the students in my conceptual physics classes. This is one of those activities where [...]
