Environmental perspective is one of the five core tasks mentioned in the Swedish Curriculum that should permeate instruction of all subjects.  WebEnglish.se suggests the time between Earth Hour 25/3 and Earth Day 22/4 to be dedicated to studies about the Earth, sustainable living and the future of our planet. Material can be found in Teaching by Calendar for these specific dates and more in the theme pages Environment 5-7 and Environment 8-9
Earth Day, April 22nd
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)
