First, visit the tap water museum and the drainage science museum with the children. There is an image contrast of world water resources, China water resources and urban water resources. Feel the water resources and how the tap water comes from. Where did all the water we used go? What will happen if we don't deal with it? What should children do to enhance understanding and inspire through physical objects, videos and dynamic simulations? This is the best way.
Second, if there is no condition to visit the museum, parents will design some questions according to the child's body shape, such as how did the water come from? Where did the used water go? Discuss with your children to find the answer. Or let children think about the change of water quantity in combination with the change of water quantity in local rivers.
Third, look for water-saving tips with children, and don't underestimate children. When they find it, they will implement it together and supervise each other. It is important for adults to set an example.
Fourth, make water saving a habit.
