Earth Hour

Earth Hour
Earth Hour is an annual international event designed to raise awareness about global climate change. The campaign encourages governments, businesses, and private citizens to turn off all unnecessary lights for an hour in order to promote conservation of energy resources. They are hoping to get one billion participants from around the globe to create a proactive, rolling blackout to send a message to world leaders that global climate change matters to the world's citizens and to raise awareness about conservation efforts happening year-round.

In 2014, Earth Hour will be held on Saturday, March 29, 8:30-9:30 p.m. local time, all over the world. Thousands of towns across more than 100 countries plan to take part. Science NetLinks and Thinkfinity offer these resources to help explore the ideas of light pollution, energy conservation, and global climate change in your classroom and beyond.
