As teachers, we like to show video clips of varying lengths to our students to introduce a new content, to enforce a concept, or to take students to locations across the globe. Videos can engage students, spark a conversation, demonstrate laboratory experiments, and so much more.

Embedded thumbnail for Human Population Through Time

From the American Museum of Natural History (AMNH)  --  It took 200,000 years for our human population to reach 1 billion—and only 200 years to reach 7 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’s resources, even as we approach 11 billion?

Embedded thumbnail for Why 2 degrees Celsius matters

We hear all the time that we need to stop the planet from warming an additional two degrees Celsius above pre-industrial levels. Why is that specific number so important though? And what happens if we exceed that limit? PBS News Hour offers some background on that climate science target (this is a complete transcript (link is external) for the video).

Embedded thumbnail for OMG - Oceans Melting Greenland mission by NASA

From NASA OMG Mission website -- Global sea level rise will be one of the major environmental challenges of the 21st Century. Oceans Melting Greenland (OMG) will pave the way for improved estimates of sea level rise by addressing the question: To what extent are the oceans melting Greenland’s ice from below? Over a five-year campaign, OMG will observe changing water temperatures on the continental shelf surrounding Greenland, and how marine glaciers react to the presence of warm, salty Atlantic Water.

Embedded thumbnail for NASA - Why Do Raindrop Sizes Matter In Storms?

Not all raindrops are created equal. The size of falling raindrops depends on several factors, including where the cloud producing the drops is located on the globe and where the drops originate in the cloud. For the first time, scientists have three-dimensional snapshots of raindrops and snowflakes around the world from space, thanks to the joint NASA and Japan Aerospace Exploration Agency Global Precipitation Measurement (GPM) mission.

Embedded thumbnail for NASA's Earth Minute series on global climate change

Did you know NASA has studied Earth more than any other planet in our solar system? It's one of NASA's most important missions and its unique capabilities in space give us a global view of our changing planet. Subscribe in YouTube to this bi-weekly animated series as NASA looks at earth science topics and explains why climate change is a big deal in 90 seconds or less.

Embedded thumbnail for Dwindling of Arctic's oldest ice since 1990

From NOAA Climate  --  Time lapse of the age of sea ice in the Arctic from week to week since 1990, updated through the March 2016 winter maximum. The oldest ice (9 or more years old) is white. Seasonal ice is darkest blue. Old ice drifts out of the Arctic through the Fram Strait (east of Greenland), but in recent years, it has also been melting as it drifts into the southernmost waters of the Beaufort Sea (north of western Canada and Alaska).

Embedded thumbnail for Ocean Acidification - The Other Carbon Dioxide Problem

From NOAA Visualizations - Fundamental changes in seawater chemistry are occurring throughout the world's oceans. Since the beginning of the industrial revolution, the release of carbon dioxide (CO2) from humankind's industrial and agricultural activities has increased the amount of CO2 in the atmosphere. The ocean absorbs almost a third of the CO2 we release into the atmosphere every year, so as atmospheric CO2 levels increase, so do the levels in the ocean. Initially, many scientists focused on the benefits of the ocean removing this greenhouse gas from the atmosphere.

Embedded thumbnail for Glaciers on Pluto - from NASA

Pluto is cold; the average surface temperature is just forty degrees Celsius above absolute zero. So how is there glacial activity on the distant body?

On Earth, glaciers form when enough snow builds up year after year to become ice. The compression of accumulated snow forces it to re-crystallize, forming larger grains. These grains grow larger, crushing out air pockets and the whole structure becomes more dense. Over the course of years, this snow will eventually become glacier ice.

Embedded thumbnail for NASA | A Week in the Life of Rain

Rain, snow, hail, ice, and every slushy mix in between make up the precipitation that touches everyone on our planet. But not all places rain equally. Precipitation falls differently in different parts of the world, as you see in NASA's new video that captures every shower, every snow storm and every hurricane from August 4 to August 14, 2014. The GPM Core Observatory, co-led by NASA and the Japan Aerospace Exploration Agency (JAXA), was launched on Feb 27, 2014, and provides advanced instruments that can see rain and falling snow all the way through the atmosphere.

Embedded thumbnail for El Niño and La Niña Explained

This video is from the NOAA Ocean Today collection. The video explains and shows the interaction between the trade winds, surface ocean movement, jet stream, and the climatic impacts. What this video shows that is not found in other videos is a map view and cross sectional view of the Pacific Ocean basin, demonstrating the trade winds blowing the warm water to the western Pacific at the same time the upwelling of the colder water is occurring in the eastern Pacific.
