Abstract
The author reports two trials of engineering design education featured inorganic materials. The first theme is the preparation of Sn-Bi-Zn alloy. This alloy is a candidate as a Pb-free solder. The students have to aim the lowest melting point for this solder. Photocell is the second theme. The students have to achieve the photovoltage above 100 mV using copper and copper (I) oxide.
