Day 159: Determining Equivalent Reisistance and The Mother of Ohm’s Law Labs take 2

Advanced Physics:

So it is essentially the last day of AP testing  that will decimate my morning classes.  Today the students took a schematic diagram and electric potential difference assessment:  Here it is:

I think it is important for students to be able to create and interpret schematic diagrams… somewhat like force diagrams.

We then completed a group practice problem solving for the equivalent resistance.  Here it is:

One of my goals here is not to make all my students experts, but to continue to practice their higher order thinking skills and problem solving skills.  The next step will be to insert some meters (both ammeters and voltmeters) and ask the students to solve for the values the meters will show.  The remaining time was small group work time with me answering questions along the way.

General Physics:

This crew also completed an assessment on drawing schematic diagrams (no EPD’s for this group).  Here si the one they took:

After this was completed they gathered data for the Ohm’s Law experiment using the spools described in the last few posts. Tomorrow we will WB it.
