A short video on designing a door bell to keep little brothers or sisters out of your bedroom. There are two design teams that use household materials, except for buzzers, to build door bells and attach them to small size doors for testing.
This short video segment addresses the engineering design cycle. A real life problem of keeping your younger siblings out of your room is presented and two design teams work to solve the problem. They test their solutions on smaller size doors. The design teams uses appropriate vocabulary when discussing the circuits.
