If you missed the chance to raise awareness of environmental issues around the Earth Hour a couple of weeks ago, you have a new chance on Earth Day this Wednesday.
Apart from Earth Day materials in Teaching by Calendar for year 3-9, WebEnglish.se also has a Theme Page with environmental materials for year 5-9.
Note that an environmental perspective is one of the four overall perspectives that should permeate all subjects according to Lgr11 (the Swedish Curriculum)
