Using a solar furnace, Si grains (~1–3 mm) were obtained within a few minutes by the reduction of SiO2 by Mg. This study presents the students’ detailed learning activities, including the isolation of Si elements, which can be identified by analyzing its chemical properties, measuring its density, and testing the detection of an amplitude modulation broadcasting. Through trial lesson practices for third-year high school students, the learning contents of Si chemistry as well as the effectiveness and renewability of solar energy are taken into account.
