Today, Earth Day, it is important to celebrate and teach kids (of all ages) about the wonders of our planet, and how to live more sustainably on it.  From now through Saturday, NASA is hosting a virtual event focused on “exploring the connections between Earth’s atmosphere, water cycle, forests, fields, cities, ice caps, and climate.” The program is called #ConnectedByEarth and will include conversations with astronauts and scientists working in space, videos, and even a “kid-friendly fun zone.”  The event is free — anyone can attend — to register, just click here.  NASA is also asking people across the globe to post an image on social media with whatever it is on Earth that connects you to our planet using the hashtag #ConnectedByEarth.  And if you are looking for a great way to explain climate change to your kids, this is a wonderful interactive guide by Julia Rosen with beautiful illustrations by Yuliya Parshina-Kottas that appears in The New York Times online.  Happy Earth Day, Friends of the Planet!
