紫カイワレ大根を用いた生命領域と粒子領域が連携した中学校理科教材の開発

抄録

An experiment using a plant of purple sprout and soil of ‘mebae gel’ were developed in order to obtain interdisciplinary teaching materials straddling biological and chemical studies. The improved cultivation method using the gel made it possible to observe the growth of the roots easily and obtain anthocyanin from the plant effectively. Moreover, the hardness of water can be analyzed quantitatively using a solution of anthocyanin. The experiments were undertaken in a junior high school and confirmed that these teaching materials are effective.
