To extend water conservation education to pre-primary levels, Water Supplies Department (WSD) has launched the "Cherish Water Campus" Integrated Education Programme – Kindergarten (the Programme) in the 2018/19 school year to all kindergartens in Hong Kong. The target group of the Programme is children aged 5 to 6 from upper kindergarten class. To provide a pleasant and relaxing environment for children to learn about the preciousness of water and the importance of cherishing it, we have developed a set of teaching kit, comprising a storybook, a booklet of suggested activities and a teacher resource book for kindergarten teachers to educate children in class, to help them develop water saving habits in daily life and improve children’s basic understanding of water related concepts.
