Letter of the week COOL SCHOOL I am a student in Pr atom 6 at Ampornpaisarn School in Nonthaburi. At my school there is a natural classroom. It is an outdoor learning centre which consists of four zones. They are a herb garden, an earthworm project, an area of making organic fertiliser and animal greenways. Raising earthworms is one of the most interesting outdoor learning projects. Earthworms can get rid of organic garbage very fast. We collect leftover food after a meal and feed them in the soil in a concrete block once a week. After a month we get earthworm manure for growing plants. on the animal greenways we can see a lot of cute birds and squirrels. They are not only free but also happy because they are living in nature. We learn and have fun together in our natural classroom
