Educator Preparation Material
Supplies needed for each student or group of students:
o
4-AA Battery pack with leads
o
Conductive dough
o
Insulating dough
o
3+ LEDs
Optional, but recommended:
o
Buzzer
o
Motor
o
Switch
These materials are all available on our web store at http://squishycircuits.com/store. We offer both kits
and individual components.
Squishy Circuits was created to be as accessible as possible. Therefore many readily-available, low
current components will work. If you are using your own, be sure to add terminals to increase the
surface area (we also recommend using aluminum terminals because it resists corrosion the best) and
ensure the component operates at 6 volts with 30 or less milliamps of current.
Safety
In general, Squishy Circuits is a very safe activity. However, some safety notes should be addressed:
The battery packs should never be shorted out (letting
the wire/terminals touch each other directly). Our
battery holders have safety features that prevent
overheating, but with other battery holders they will
quickly warm up and could cause burns if shorted.
When doing any electrical project, batteries should
never be shorted directly.
LEDs should not be hooked directly to the battery
packs. They will burn out and may pop. LEDs require a
resistor to limit the amount of power flowing through
them. With Squishy Circuits, the conductive dough
acts as the wire and a resistor, so they’re safe to use
with the dough.
