Ucar: Aerosols: Tiny Particulates in the Air

Condensing water warms the air around it. Young scholars consider this concept as they experiment with air temperature around evaporating and condensing water vapor. They simulate the formation of clouds to experience the associated...

Water vapor released by trees in the Amazon creates a floating river. In fact, it's the largest river on Earth! A video presentation examines the science behind the water vapor and explains how rains seeds form to create clouds.

What makes air fresh or not so fresh? The solution is solution chemistry! Explore homogeneous mixtures with a video from the JFR Science series. The narrator explains a variety of solution terms, how to classify solutions, and how people...

Up to 75 percent of the stars in the Milky Way are red dwarfs, yet we can't see any from Earth. The video explains what makes red dwarf stars unique. It highlights the potential for finding aliens or a planet humans could live on once...

What happens in the Arctic doesn't always stay in the Arctic. Follow along with this short video as it investigates how small changes in the temperature of Arctic regions can have dramatic effects on the global climate through a series...

There are so many galaxies in the universe that the vast majority of them are too distant for the human eye to perceive. An astronomy video discusses the Hubble Telescope's Deep Field image from 1995 and the eXtreme Deep Field image...

For this lesson on greenhouse gas, students conduct experiments to detect and collect carbon dioxide, then use titration to determine how much carbon dioxide is present in an indicator solution.

What is energy? Where does it come from and how does it move from place to place? Learn about the different kinds of energy, how energy changes form, and what heat really is. With great visuals to accompany some difficult concepts such...

Air is a mixture of naturally occurring gases and human-made air pollutants. Learn more about these gases and the role they play in our atmosphere.

Help your class determine the types of pollutants coming from vehicle exhaust. Groups use an air quality monitor to determine the emissions from different vehicles, to gain knowledge about combustion energy, and to predict how the...
