“Green Touchology” is a set of all-material light-blind shared tactile teaching aids. Natural science is the first chapter of the third grade of primary school children's exposure to nature and life technology, and scientific abstract concepts and proper nouns are easy for children to feel frustrated in learning. Therefore, the team builds on the existing syllabus and develops new teaching aids to help with scientific learning. Merck cells are the tactile sensing of all skin surfaces, and we have introduced the concept of 'Activating Merck Cells' to exert the highest value of tactile learning through the application of all materials.
