Hands-On-Physics
IEU Extension
In this activity you will complete the installation of your alarm circuit
in a model house. Build a house out of cardboard, complete with at least
one window or door that you can alarm. Its also convenient if the roof detaches
so you can access your circuit board easily. Feel free to add flourishes--you
may want lights to go on as well as an alarm, you may want a deck on your
house.....
Test out your alarm system thoroughly, so that when a burglar tries to enter
the alarmed part of your house the alarm reliably goes off.
If you're stuck...
- Think about what parts of the circuit you DON'T want the thief to
break. Make sure these aren't around your alarmed window.
- Think about what part of the circuit you DO want the thief to break,
and put that part around the window.
- If you add extra components, like light bulbs, do you want them wired
in series or parallel? Check both ways and see if your ideas were correct.
- Make your alarm system easy to reset once its been tripped.
