The pupils' cooperative "Telegrin" includes students from grades 5 to 8 and has four sections: floristic, horticultural, arranger, and ceramic. The cooperative aims to develop students' work ethic and appreciation for nature. In the floristic section, students work in the school garden to learn gardening skills. In the horticultural section, they collect fruits and plants to make jams, marmelades, and medicinal teas. The arranger section decorates the product packaging in an original way using recycled materials. The cooperative's products are exhibited for sale.
