    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

    Massive Tornado Outbreak on Tornado Alley

    The week of May 19 brings dozens of tornadoes to Tornado Alley in the states of Oklahoma, Kansas, Iowa, Illinois and Missouri. On May 20th, a massive tornado struck Moore, Oklahoma, devastating communities - destroying over 100 homes and hitting two elementary schools and a hospital - with many casualties and deaths. Our thoughts are with our friends and colleagues suffering from these storms. For more on the May 20th storms, see the NOAA Storm Prediction Center Storm Report.

    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

Kids' Space

Welcome to Kids' Space - a place where we have collected a variety of resources and things for you to do that we think you will enjoy. If you have suggestions of other things you'd like to see added to our collection, please let us know! The links below provide links to games and interactives, our Ask a Scientist collection where you can browse previous question and answers and post new ones, our Journal tool, our Virtual Postcard interactive that you can use to send postcards to your friends, and links to other online resources. Enjoy!
Play our <a href="/earth/climate/carbon_cycle.html">Carbon Cycle game</a> and follow the path of a carbon atom as it moves between reservoirs in the Earth system. For millions of years you were underground in fossil fuels. Now, you have been released into the atmosphere as humans burn fuels. Your objective is to get to all the places that carbon is stored. Earn extra points by correctly answering the carbon challenge questions at the yellow stars.<p><small><em></em></small></p>Like the Earth's environment, the space environment is getting more and more cluttered. There are currently MILLIONS of man-made orbital ruins that make up "space junk". Play our <a href="/games/junk_intro.html">Junk in Space game</a> and find out about all the junk in space, and how it got there. Your objective is to capture all the junk you can - but be careful - don't catch a satellite, spacecraft, or an astronaut! Three strikes and you're out!<p><small><em></em></small></p>Does any planet have a stronger magnetic field than Mars? Which planets have a greater mass than Jupiter? Which are denser? Which are larger? Find out while playing the Solar System Edition of <a href="/games/order_planets_intro.html">Order It Up</a>! Measures of size and scale help us understand the magnitude of objects. Play with scales while trying to arrange planets by magnitude of mass, size, temperature, density, distance, gravity or magnetic field. Correctly order the planets and you unscramble a mystery picture!<p><small><em></em></small></p>Play our <a href="/games/sudoku/sudoku.html">Eight Planets and a Dwarf Sudoku</a>! The regular rules of Sudoku apply - each planet can only appear once in each column or row, and only once in each 3x3 box. Learn more about the planets, too! You can vary the game from very easy to challenging.<p><small><em></em></small></p>The <a href="http://www.starcount.org">Great World Wide Star Count</a> is an international Citizen Science campaign. The purpose of this event is to encourage everyone to go outside, look skywards after dark, count the stars they see in certain constellations, and report what they see online. This Windows to the Universe Citizen Science Event is designed to encourage learning in astronomy! Have fun everyone!<p><small><em></em></small></p>Explorers, both from long ago and today, use journals to record where they travel and what they discover. With this <a href="javascript:wb_onclick();">online journal</a> you can keep a record of the places you have been, the things you have seen, and what you have learned within the Windows to the Universe web site!<p><small><em></em></small></p>
