Sexism in Storm Names - Gender Makes a Difference

Earth and Space Science Gender Weather and Climate

Studies show that people react differently to male and female named storms. There is more preparation and fear of storms with male names, such as Victor, versus a storm named Christina. As a result, there are serious implications of this unconscious gender bias. Listen to this audio story to learn more.

Gravity's Strong Pull is Actually a Weak Force

Earth and Space Science Physical Science Forces and Newton's Laws

Even though it is the weakest of all forces, gravity is why we exist. Gravity keeps the earth, moon, and sun in orbit. It keeps us on the ground instead of floating in space. Listen to hear how gravity affects the velocity in rockets, the shapes of planets, the trajectories of baseballs, and even the strength of the human leg bones.

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.
