"It's A Wired World" is formatted for use either in cooperative
learning groups, or to support teacher presentations in classrooms
or informal settings. Some of the activites require special materials.
This is a complete list of the materials needed to perform the
experiments in the booklet. This list gives quantities for a single
group or teacher. Simply multiply by the number of groups to find
how much you will need for a full class. Where relevant, this
materials list includes Radio Shack part numbers for ease of purchase
in North America. These are included as a convenience, not as
an endorsement of Radio Shack. Comparable materials are available
from other sources, such as your local hardware store.

NOTES
- A lamp is a light bulb.
- Although not necessary the lamp holder specified above has screw
terminals which makes it easy to attach wires.
- *About the experiment on page 5, Electricity and Water: The resistance
of the salt water means you will have to use more voltage than
you would otherwise to get the bulb to light brightly. If you
touch the nails together, you may burn out the bulb instantly
if the voltage is too high for it. This is the reason you might
want to use a higher voltage lamp.
- Jumper leads (RS# 278-1156) are slightly more expensive, but easier
and faster than alligator clips because jumper leads already have
wires attached to the clips.
