We were presented RENEW SCHOOL project and its purpose. Pupils are shown how to save energy, to discuss renewable energies, We showed them some energy-saving houses and their characteristics, what will be building in the future, which building materials they know and what can be made of wood (wheel, sink, bridge toys, ……). We also looked at how the wall consists of a wooden house and prepared a blackboard with building materials, which will serve as a teaching aid. We have a number of practical experiments, and then the pupils consisted of various solar models and created from pieces of wood.
