This resource gives all the basic resources for a project on sustainability. There is a letter inviting students to design a new school that your headteacher wants to build. There is a list of sustainable elements with prices that your students can use to design the school sustainably. There is also a criteria sheet (which was co-created by students) that they can self and peer assess as they go, and you as the teacher can use as well if you desire. This is a great fun way to assess your students understanding of sustainable design practises.
