Things to think about as you Mess Around
- Tools & Materials
List, description, and suggestions for use of tools & materials available
for Messing Around
- Activities: Hands-on
activities which are components of the Messing Around research
Understanding how to build circuits and to draw and follow circuit diagrams,
are basic skills you will use throughout this course. In this unit you'll
begin with simple circuits and review or develop some skills and learn the
language of electronics. Two of the most important terms are
voltage and current.
The voltage is the energy difference per charge between two points.
If a voltage exists, and the two points are connected, the charge will move
and current will flow.
Understanding this is vital to using electricity safely.
Sustained currents can cause injury, Be cautious!
Tools & Materials
You will need the tools, wire, buzzers, battery, battery clip, switches,
circuit board, solder, light bulbs, multimeter, resistors, and transistor
for the messing around activities.
- Soldering --You
will solder wires and clip leads.
- Simplest circuits--You
will wire a buzzer with a switch, using a circuit board.
- Series and parallel
connections--You will wire light bulbs in various ways to observe
the effects of series and parallel circuits.
- Using transistors--You will
follow a circuit diagram to build a security system that will set off the
buzzer when disturbed.
