This project deals with sustainability through study of wood: where it comes from, how it is made, how it can be used (in art, technology, architecture, …) and all above how it can be reused and recycled. Purposes are: - to help students recognize the richness of wood; - to raise students’ awareness of respect for the environment by using different communication languages and direct experiences; - to facilitate students to develope competences in sustainability, especially about circular economy. In this way, they improve their foreign language communication skills and the use of ICT as a means of communication and expression. Collaboration and common cultural encounters will broaden students' horizons and the interdisciplinary nature of the project will help develop basic skills.
