    As far as we know, much Japanese science education for young children involves the biology of natural experiences and observation, but little content from physics and chemistry. However, foreign countries report systematic lessons in the latter fields. However, directly importing lessons and presenting them in Japanese elementary and lower secondary schools is difficult. Therefore, we created a science education program with the following two features: (1) Substances, objects, and phenomena closed to Japanese children are included and (2) lessons are suitable for presentation at a nursery school, kindergarten, and science museum. Specifically, we developed an experimental classroom on "materials and buoyancy" in physics and presented its lessons in a nursery school, kindergarten, and science museum. An assessment of its value was also performed.

    Diffusion of hydroxyl groups in silica glass through an interface formed by binding between high-hydroxyl (ca. 1200 wt.ppm) and low-hydroxyl (ca. 130 wt.ppm)-containing silica glasses in the temperature range of 900–1150 °C was investigated. Although the theoretical curve with a hydroxyl-concentration-independent diffusion coefficient deviates from the experimental curve, the diffusion coefficients obtained by fitting to the experimental results by the least squares method coincided with the “effective diffusion coefficients” in the literature, which were obtained from the total absorption change in the IR absorption peak for the hydroxyl group using thin samples. By the analysis considering the hydroxyl concentration dependence of the diffusion coefficient, we showed that the diffusion coefficient is proportional to hydroxyl concentration at each temperature, which is consistent with the model of the diffusion: SiOSi + H2O = 2SiOH. On the basis of this scheme, we tried to evaluate the diffusion coefficients of molecular water using equilibrium constant in the literature.
