Pbs Learning Media: Deep Sea Vents and Life's Origins

Observe how the sea ice changed in 2016 after it reached its maximum extent in late March and proceeded through the melt season in this video from NASA. Scientists study sea ice because it influences global climate. Resouces include...

What if life began deep in the ocean? One experiment set out to prove the theory that life began around deep sea vents. This video shows the results of this experiment and it what it taught us about the origins of life. Closed caption...

Take a submersible down to the seafloor. As you descend, passing through the ocean's sunlight, twilight, and midnight zones, you can observe how temperature, pressure, and light levels change. When your submersible reaches the seafloor,...

Scientists study ice sheets because they influence weather and climate, playing a role in atmospheric and ocean circulation. Ice sheets can also have huge impacts on global sea levels because they store so much water. Explore this...

Take a deep dive into oceanography. The online interactive allows for learners to board a submersible to dive to the bottom of the ocean to investigate sea vents. On the way down, individuals see different marine life at different...

Learn about the formation of elements from this video by NOVA and how these elements were incorporated into Earth when it formed. Closed caption available. [2:27]

How did life first arise on earth? There are many theories and scientists Stanely Miller and Harold Urey set out to recreate the environment of early earth in order to find some answers. Watch this video from NOVA to see the results of...

The Arctic plays an important role in regulating Earth's climate. The region reflects much of the Sun's energy and helps keep the planet cool. Data collected by NASA have revealed that sea ice in the Arctic has steadily declined over the...

Examine this visualization by NASA to understand how the warming of the Arctic region has caused the sea ice extent to decline by 40%, thereby throwing our earth's energy budget off balance. Extensive resources included are teaching...

This interactive activity from McDougal Littell/TERC visualizes the effects of the Exxon Valdez oil spill, factors that influence oil spill behavior and impact, and techniques used to contain and clean up oil spills at sea.
