Earth Hour is a grassroots movement organized by the World Wildlife Fund to unite people to protect the planet and to call for action on climate change. What started out as a lights-out event in Sydney, Australia, in 2007 has grown into a larger movement in more than 7,000 cities worldwide, according to earthhour.org.

At a minimum, people can simply turn off their lights on Saturday, March 28 from 8:30 to 9:30 p.m. to participate in Earth Hour. If you plan on burning candles in lieu of using electricity, organizers of Earth Hour suggest using 100 percent beeswax or soy candles, which are nontoxic, non-allergenic, and better for the environment.

Follow our simple instructions to make your own beeswax candles, here.

What else can you do during Earth Hour?

Have a picnic by candlelight.
Set up a blanket outside if it’s warm, and enjoy a snack under the stars. (Try to spot these constellations.) If it’s too chilly, your living room floor will work just as well!

Create shadow puppets.
Pinterest has instructions for a variety of puppets you can create with your hands, here.

Make a pledge for the planet.
Have everyone think of eco-minded goals that each person can work on over the year or one big goal that everyone can do together. Then create a poster with your plans and hang it in a place where everyone can see it so you have a reminder all year long. A few goals to consider from The Earth Hour Playbook: using reusable bags as often as possible instead of paper or plastic bags; buying products with biodegradable packaging; and walking or cycling when possible.
