Abstract
Yutori kyoiku, or a reduction in normal school hours, began in elementary and intermediate education ten years ago, and consequently the time available for experimental work in science courses has been significantly reduced. We have been holding a scientific experimentation course for elementary school children, using microscopes, during summer vacation for the past six years. Recently, a new educational guidance advisory has been issued to improve the scientific and mathematical abilities of children. Accordingly, we are cooperating with teachers in elementary and intermediate schools to provide advanced scientific education using ceramic materials.
