Teachers introduced these strategies to their respective students and some of the outcomes are
discussed below. In the electronics example below, students aged 11 years, used a standard alarm
circuit configuration to generate some ideas based on their personal lives. Examples shown below
include an alarm which senses the heat in a baby’s milk bottle; the heat of the water in a baby’s bath
(which doubles as a bath toy); a water sensor that detects the height of the water whilst running the
bath; and a broach which changes colour depending on the humidty (humidity sensor) which reminds
the wearer to drink some water in humid conditions.
