The new national curriculum regarding Technology Education at lower secondary school started from 2012. "Energy conversion" is a must for all students, and the new contents on electrical power generation, its storage and power conversion were introduced at 6th grade of primary school from 2011. Hand-driven power generators have been widely used in class room, that generate electrical power using electro-magnetic induction. There arealternative methods for power generation such as piezoelectric device, electrets device, thermo-electric device and solar cell. Among these devices, it is easy to use piezoelectric device in classroom We developed learning materials on electrical power generation using piezoelectric device. First, the condition that maxmum power can be obtaind from piezoelectric device was investigated by experiment. Second, handshakingelectrical power generator and shoes with piezoelectric devices were developed. Finaly, power generation floor on which students can step and LED indicator by which storaged power can be checked were developed.
