Walking in Space

Earth and Space Science Elementary Atmosphere

There are only a small number of people who have been in space. A smaller number of people have been outside a space station, tied only with a tether, floating in space. There is a huge amount of training and planning that goes into a space mission, but sometimes things still go wrong. Now astronauts have fewer opportunities for space travel since NASA ended its shuttle program in 2011. Listen to these astronauts as they describe their experiences floating over the Earth.

Clean Power Plan

Environment Climate Change Atmosphere

NOAA, the National Oceanic and Atmospheric Association, called 2014 the hottest year on record and cited the changing climate as the cause of extreme storms, droughts and floods around the world. Slowing climate change is a top priority of President Obama, who unveiled his Clean Power Plan on August 3rd. The Plan would limit the carbon that power plants can release, cutting emissions by a third over 15 years, as well as boost the use of renewable energy. China and the U.S. are the top contributors of carbon emissions, and Obama wants the U.S. to lead the way and encourage other countries to set limits as well. He faces significant political opposition to the Clean Power Plan, even though two of three Americans support the idea.

Birds Signal Climate Change

Life Science Earth and Space Science Climate Change Ecosystems Atmosphere

A recent report shows carbon dioxide levels in the atmosphere rose at a record rate in 2013. Humans aren’t the only species affected by these changes. A new report by the National Audubon Society makes it clear that bird species in the U.S. and Canada are at risk of losing their habitats and potentially their lives due to climate change. Listen to this public radio story with your class to learn more about the links between changing temperatures and bird habitat and survival.

Clearing Carbon From Our Air

Earth and Space Science Environment Climate Change Human Impacts Atmosphere

Carbon exists in all living things, including proteins, DNA, and fats. When living things exhale, the result is carbon dioxide. As our world develops, we produce more carbon dioxide with the burning of fossil fuels and the use of cars, trains, and planes. This gas is causing an imbalance in the atmosphere which affects the warming of the planet. Listen to hear how much carbon dioxide humans are responsible for and the effects of global warming.
