Science/Strand IV/Content Standard 1/High School/Benchmark 4
Benchmark Question: How do electricity and magnetism
interact with matter?
Focus Question: How is current controlled in simple
series and parallel circuits?
As an introduction to
parallel and series circuits, the teacher will give students bulbs, some
wire, switches, strings of Christmas lights, and dry cells (batteries).
Students will design and construct two circuits: one circuit has switches
that turn off all lights when open and one circuit has switches that
control individual lights. During a class discussion, students will draw
conclusions from what they have observed and will explain how the circuits
work. Students will distinguish between series and parallel circuits and
will draw diagrams in their journals.
