Physics & Physical Science Demos, Labs, & Projects for High School Teachers

Posts Tagged ‘Parallel Circuits

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 bulb.  I helped them out by drawing the schematic for the first problem.  The attached document is pretty much self-explanatory, but I would suggest you have the kids read the last couple questions before they start building.

I had the kids in groups of two.  Each group needed a 3v battery pack (2-D cells), two light bulbs in holders, two knife switches, and about 6 sets of alligator jumpers.  You could use pre-cut wires, I had the jumpers available.

With the introduction to series and parallel circuits, the lab took the entire class period to complete.


What’s New in 2013/2014?

Every year brings a change, this one is no exception.

I will be picking up the sophomore honors Algebra II class to keep them separate from the juniors. This should help accelerate them and put them on a stronger track towards Calculus. Looks like there will be only one section each of Physics and Calculus, but still two of Robotics & Engineering.

Hot topics this year are going to be the Common-Core Standards, Standards-Based Grading (SBG), improving AP Calculus scores, and somehow adding Python, maybe as a club.

Just a quick poll to help me understand who is stopping by my blog.

Yeah sure, lots from America, but look who else is here…

If you are badly in need of more email or for some reason jonesing for a physics fix, enter your email address so I can bother you with my newest rant on science.
