#Teachingisfun has been supporting Earth Hour for years!
It’s a wonderful opportunity to use #yourpower to change climate change! Join The Lights Off Event. Earth Hour was famously started as a lights-off event in Sydney, Australia in 2007. Since then it has grown to engage more than 172 countries and territories worldwide. Earth Hour 2017 is on 25 March 2017, 8:30 pm.
