We built a mini solar furnace using Fresnel lenses (295×360 mm). It was found that the temperature at the focus was over 1200°C. Reduction of several metal compounds (Fe2O3, Co3O4, NiO, Cu2CO3(OH)2) was carried out by the mini solar furnace. This resulted in producing visible particles of Fe, Co, Ni and Cu. On the basis of the above findings, we proposed a learning activity that adopted the experiment of reduction of Fe2O3 using the mini solar furnace. The activity was conducted in a high school and we confirmed that the students were interested in solar energy.
