This is an environmental project about water, its knowledge, use and care as an essential resource for life on the planet. Based on the famous sentence by Bruce Lee: "Be water, my friend". Students will learn together through the scientific principles, investigating, making experiments, sharing their experiences and discussing their conclusions. To develop this project, we'll work with CLIL and ICT as main methodologies, taking account inclusion, cooperation and equality around all the activities. The final product will be an e-book, which could be used for our schools as an educational resource.
