Visionlearning: Atmosphere and Oceans: Factors That Control Earth's Temperature

Man has dreamed of outer space travel for hundreds of years...but, what about inner-Earth travel? Could it work? Young scientists explore the notion of jumping into a hole through Earth and the factors that affect the journey, such as...

Explore thermal energy with this short episode. Jiggling molecules and hand-drawn animation help to explain that just because something has a lot of thermal energy, it doesn't necessarily feel hot to the touch. This is an ideal addition...

An explanation of the different parts of the atmosphere and how pressure and temperature changes at different altitudes.

An explanation of how the Earth's atmosphere has changed over time. Evidence that helped scientists understand these changes is presented.

An explanation of the Earth's atmosphere and how it has evolved over geologic time.

Is atmospheric carbon dioxide really to blame for global warming? Young environmentalists analyze historical carbon dioxide and temperature data during a multimedia activity from PBS's Weather and Climate series. High schoolers read...

Get lost at sea amid colorful ocean currents! Learners discover the patterns of movement and temperature in the North Atlantic's currents through a simulation, part of PBS's Weather and Climate series. The resource contains background...

High schoolers describe and compare the layers of the atmosphere. They explain how to measure the temperature of the atmosphere and discover what causes the atmosphere to heat up in some places more than in others.

While clouds may not make for the most enjoyable weather, they play an important role when it comes to regulating the temperature of the earth. Watch this video and learn how these giant masses of water droplets actually help to cool the...

Is Earth's energy flow a little off balance? Explore our energy budget using a click-through interactive. Scholars discover the many factors that move solar energy around the planet and why the system is no longer in equilibrium.
