To develop experimental teaching material for studying the process of storage starch degradation in plant seeds, we analyzed germinating seeds of various species, of which buckwheat (Fagopyrum esculentum Moench) proved successful. With our material, changes in glucose concentration due to starch degradation, as well as factor amylase activity, were easily confirmed by the urine test strip method and the starch filter paper method, respectively. The material is expected to be a useful teaching tool, especially for research activity, as students must first hypothesize the metabolic relationship between glucose concentration and amylase activity before verifying their hypothesis through experiments. The developed material focuses on glucose-based energy metabolism in plant seeds and therefore facilitates an improved understanding of germination from observation of morphological changes in seedlings to more advanced aspects such as seed biochemistry.

This study developed the dissection of the eye as the teachingmaterials in Cambodia. The dissection of the eye was firstly introduced in Cambodia. The cow eye and pig eye were dissected and discussed. The lecturer made the lesson of “pig eye dissection”to the high school students and we analyzed the effect of this lesson. The students were interested in the dissection of the eye. However several students could not recognized a few parts of the eye that includes retina. Based on these results, the revise points are discussed.
