Teaching Children about Circuits
(Sample Story Board)
1
Goal
• Your task is to help students develop the idea
that electricity travels in a circle in a simple
circuit (complete loop of conductors).
2
Scene 1
TEXT
• You have spent 40 minutes
allowing students to explore
what happens when they place
batteries, bulbs, and wires in
different configurations. The
students have discovered that
if they place a battery, bulb,
and two wires “in a circle” the
bulb will light.
•
However, two students
(“David” and “Ricardo”) begin
an argument about the
direction that the electrons
travel. Watch the following
video that shows this
argument.

David’s Idea
Choice 1
TEXT (Choice)
Which student’s
idea do you think
is consistent with
the scientifically
accepted idea?
David
Ricardo

Choice 1-David
It seems you have a good understanding of
electric circuits. If you’d like to review your
understanding of circuits, here are some
resources.

understanding of circuits. Here are some

Choice 2
TEXT (Choice)
What would you do next?
A. You responded with, “Have the students
look up the answer in a book or on the
internet.”
B. Ask both students what evidence they have
to support their ideas.
C. Propose a test that will challenge Charlie’s
idea.
D. Ask the rest of the students what they think.
Choice 2-A
Your response was, “You responded with, “Have the students look up the answer in a book
or on the internet.”
The students find out that electricity travels in a circle and that David’s idea is correct. The
conversation among the students ends. The students are all able to state that electricity
travels in a circle around the circuit. However, a week later, Ricardo answers a question
about the direction of travel of electricity incorrectly. He again stated that electricity
traveled from both ends of a battery and met at the light bulb.
What do you know about how children learn science that might explain why Ricardo’s ideas
might have reverted to the ideas he argued in class.
