Earth Day - Tuesday, April 22, 2014

Happy Earth Day! 

Do you have plans to celebrate Earth Day 2014 with your students?  Are you still looking for some ideas on what you can do and share with your classroom?  We have received some recent updates on activities being planned by NASA and the EPA that we want to pass along!  Be sure to check out National Geographic's Earth Day Facts and History, and be sure to explore the online "hub" of Earth Day celebrations at the Earth Day Network for additional inspiration.

Make a #GlobalSelfie with NASA on Earth Day! 

NASA invites you — and everyone else on the planet — to take part in a worldwide celebration of Earth Day this year with the agency’s #GlobalSelfie event.

The year 2014 is a big one for NASA Earth science. Five NASA missions designed to gather critical data about our home planet are launching to space this year. NASA is marking this big year for Earth science with a campaign called Earth Right Now, and as part of this campaign the agency is asking for your help this Earth Day, April 22.

While NASA satellites constantly look at Earth from space, on Earth Day NASA is asking you to step outside and take a picture of yourself wherever you are on Earth. Then post it to social media using the hashtag #GlobalSelfie.


What’s a #GlobalSelfie?

Two people pose with a NASA #GlobalSelfie signNASA astronauts brought home the first ever images of the whole planet from space. Now NASA satellites capture new images of Earth every second. For Earth Day NASA is trying to create an image of Earth from the ground up while also fostering a collection of portraits of the people of Earth. Once those pictures stream around the world on Earth Day, the individual pictures tagged #GlobalSelfie will be used to create a mosaic image of Earth — a new “Blue Marble” built bit by bit with your photos.

Need an idea of what kind of picture to take? Get outside and show NASA mountains, parks, the sky, rivers, lakes — wherever you are, there’s your picture. Tell NASA where you are in a sign, words written in the sand, spelled out with rocks — or by using the printable signs they have created that are available at the bottom of this linked page.

The Earth mosaic image itself and a video using the images will be put together and released in May.

How do I take part?

NASA will be monitoring photos posted to five social media sites: Twitter, Instagram, Facebook, Google+ and Flickr.

Post your photo to Twitter, Instagram or Google+ using the hashtag #GlobalSelfie, or post it to the #GlobalSelfie event page on Facebook or the #GlobalSelfie group on Flickr.

Why a #GlobalSelfie?

NASA scientists have helped identify thousands of new planets out in the universe in recent years. But the space agency studies no planet more closely than our own. With 17 Earth-observing missions orbiting our home planet right now — and several more launching this year — NASA studies Earth’s atmosphere, land and oceans in all their complexity.

This satellite data helps NASA scientists piece together a clear picture of our planet from a scientific viewpoint. On this Earth Day, NASA wants to create a different picture of our planet — a crowd-sourced collection of snapshots of the people of Earth that NASA can use to create one unique mosaic of the Blue Marble.

So, come April 22, take a second to step outside and join NASA in celebrating our home planet.

The EPA wishes you a Happy Earth Month

April 22 is Earth Day, but the EPA ( is celebrating all month, sharing a new tip each day to help you act on climate change.  Below, the EPA has listed many ways you can take action yourself and spread the word to your friends and family. Try one or many, but either way, let’s all #ActOnClimate!

Help the EPA get the message out
Help the EPA share a message at noon on Earth Day, along with the link to a page full of things everyone can do to act on climate. The EPA is using a new system called
Thunderclap to coordinate, so a message will go out from everyone at noon on Earth Day.

The message is: “For Earth Day, I commit to protect the climate. Take small actions that add up! #ActOnClimate“

The EPA needs your help, both to send the message and to invite your friends to send it. Join the effort at, or if you want more information about how it works, see the blog post:

Share daily tips through the EPA website and social media
The EPA has created 30 daily tips to act on climate, and they are posting one each day.

Join a Twitter chat about climate issues
The EPA is having experts available to discuss various climate issues on their @EPAlive Twitter account every Tuesday in April:

  • April 8, 2:00pm EDT - What can I do to act on climate?
  • April 15, 2:00pm EDT - What is EPA doing to act on climate?
  • April 22, 2:00pm EDT - EPA Research and Climate: What does the research show about climate change and what we can do about it.
  • April 29, 2:00pm EDT - Why is climate action important for our water?

How can you join the conversation? Just follow @EPAlive and the #ActOnClimate hashtag on Twitter. Ask the EPA a question or share your ideas, or just read along with the conversation. In addition to using Twitter, the EPA is publishing a blog post for each chat, and you can ask your questions or send your thoughts as comments on the post. Here’s the first one:

The EPA looks forward to working with you to #ActOnClimate!
