Today in PAE, we did an interactive circuits lab. I assigned the students to create 3 different circuits from the PHET Interactive Circuit Construction Kit: DC – Virtual Lab hosted by University of Colorado – Boulder.
Circuit 1 was a simple series circuit consisting of two lights, two batteries, and a switch:
Circuit 2 was a somewhat easy series circuit consisting of one light, three batteries, a switch, and a 120 Ohm resistor:
Circuit 3 was a parallel circuit consisting of three lights, each controlled independently with a switch:
Circuit 4 was a parallel circuit identical to circuit 3, but had a series “master switch” in it:
Circuit 5 was a short circuit with an over-heated power supply:
The students appeared to have fun with the lab and were engaged the entire class time. Thank you UC-Boulder for this nice interactive tool!
