The Great Bookbag Alarm
Jump to "Understanding the Speed and Acceleration Formulas"
Jump to "Periodic Table of Elements Game"
Purpose:
To allow the students to design and build
their own series circuit/bookbag alarm -- a culminating activity
to the section on DC series circuits.
Motivation:
To develop a device to keep friends,
relatives, nosy siblings and teachers from going through a
student’s bookbag.
Equipment:
On the demonstration table will be a variety
of wires, buzzers, bells, lights, batteries, battery
holders and clips, wire cutters and paper clips. The group
will take what they think they need.
Procedure:
1. The class will have one period to
construct a successful device, diagram it and demonstrate it.
2. The batteries and as much of
the wiring as possible must be concealed within the bookbag.
3. When ready, the teacher will attempt to open the
bookbag. If the teacher can open the bag and remove a book
without setting off the device, then the students must try again.
4. If the device works as
planned, the students must draw the circuit diagram and be
prepared to describe it to the class.
