During the first year of the project, the Bulgarian students posted a word search game about the environment on the Twinspace.

Last week, I used it to introduce the topic of sustainability during a lesson with the class 1STI2D. Here are some students' work. Then, altogether they wrote a definition for all the words they found.

Chloé and Martin who participated in the last Bulgarian meeting had already done it, so they could help. But they couldn't answer their classmates' questions about the letters EVsE. They said it means something in the field of environment, but couldn't remember what. Please, could anyone help us?
