"Reduce plastic" is a project aimed at students aged 9/10. The disciplines involved will be linguistic, science, and technology. The aim of the project is to get to know each other through letters or emails, and then exchange posters about environmentally friendly products to save the planet and promote sustainability. The poster will include the benefits of the product for the environment and the instructions on how to make it. Afterwards, partners can try to make one of the products proposed by their partners.
