  • SciGirls | Terrific Pacific 01: Observations

    The SciGirls participate in Seafloor Explorer and make observations of the seafloor, looking at what the seafloor is made of and what animals live there. Some citizen science projects involve making observations of images gathered by instruments.

    Grades: 5-8
  • Antarctic Ecosystem

    In this interactive activity adapted from the Woods Hole Oceanographic Institution, learn about seasonal environmental conditions in the Antarctic and their influence on the southern polar ecosystem. Investigate the variety of organisms that inhabit this unique ecosystem during summer and winter. Additional information reveals how significant factors, including food supply and sea ice, respond to changing climate conditions.

    Grades: 6-12
  • Tides | Crash Course Astronomy

    Explore the world of tides, and learn how they have shaped most objects in the universe. What is the relationship between tides and gravity? How do planets and their moons become tidally locked? What would happen if you were 300km tall? Find out in this episode.

    Grades: 9-12
  • Global Ocean Circulation

    In this video from NOVA: “Earth From Space,” learn about patterns of global ocean circulation, which distribute heat around the planet. Differences in the density of water masses drive large-scale ocean currents. Dense water forming over the continental shelf of Antarctica is exported to the adjacent deep ocean, creating streams of very cold water that spread northward along the sea floor into the global oceans. Visualizations show the constant motion and flow of ocean currents. The ocean and the atmosphere are closely connected and are responsible for maintaining Earth's relatively stable climate, providing a hospitable environment for life.

    This video is available in both English and Spanish audio, along with corresponding closed captions.

    Grades: 6-12
  • The Sun | Crash Course Astronomy

    Phil takes us for a closer look at the two-octillion-ton star that rules our solar system. We look at the sun's core, plasma, magnetic fields, sunspots, solar flares, coronal mass ejections, and what all of that means for our planet.

    Grades: 9-12
  • Eclipses | Crash Course Astronomy

    In this episode, Phil breaks down what happens during a solar and lunar eclipse and provides tips for safely viewing a solar eclipse. Learn how the Ancient Greeks calculated a close estimation of the earth and moon's actual size two thousand years before the invention of the telescope.

    Grades: 9-12
  • SciGirls | Star Power 01: Mentor Moment

    In this SciGirls segment, a group of girls and their mentor collect their first piece of data for the World Wide Star Count. They carefully follow the procedure, and they learn about the distance and location of the stars visible in the night sky.

    Grades: 5-8
  • SciGirls | Star Power

    This activity, presented by SciGirls, teaches students all about light pollution—outdoor lighting which threatens our ability to see the stars at night, and which disrupts animals' mating, migration, and predation behaviors—and what they can do to prevent it.

    Grades: 5-8
  • SciGirls | Star Power 04: Design

    In this SciGirls segment, a group of girls design a prototype light cover to prevent light pollution. Their prototype directs light up instead of down.

    Grades: 5-8
  • Pollution | Crash Course Ecology

    Hank talks about the last major way humans are impacting the environment: pollution. Pollution takes many forms - from the simplest piece of litter to the more complex endocrine distruptors - and ultimately, humans are responsible for it all.

    Grades: 9-13+
  • Deep Ocean Volcanoes | Ocean Today

    Most of the volcanic eruptions on planet Earth happen in the ocean! In 2009, marine scientists discovered the deepest ocean eruption ever found in the West Mata volcano in the Pacific Ocean. The kind of lava that it was spewing, called boninite lava, is some of the hottest lava on Earth and you can see some of the explosions of molten rock in this video. Scientists compare it to a spectacular underwater fireworks display at nearly 4,000 feet deep. They also found shrimp living near the volcano's most active areas. This glimpse into undersea volcanic activity and life helps scientists understand how processes deep within Earth shape the surface and how life adapts to some of the harshest conditions on our planet.

    Grades: 4-12
  • Researching Impacts of Ocean Acidification

    Explore how rising ocean acidity is affecting animals in this video from NOVA: Lethal Seas. In laboratory experiments, researchers found changes to the brain chemistry and behavior of fish that were exposed to high levels of carbon dioxide (and, therefore, higher acidity). They repeated their experiments at a coral reef in Papua New Guinea where CO2 levels are extreme. They found that fish that grew up in areas of higher CO2 and, consequently, higher acidity do not avoid the smell of predators. The CO2 seems to have affected their cognitive ability so that they do not avoid the smell of a predator, even though they can still identify a predator's odor.

  • Nuytco's Deep Sea Exploration | Big Pacific: Mysterious

    Explore the depths of the ocean off the coast of British Columbia with Phil Nuytten, a pioneer in deep sea exploration. Once thought to be barren, this stretch of water is home to an animal believed to be extinct: the glass sponge. On his journey, Nuytten explores a 20 mile long reef filled with glass sponges. At nine thousand years old, glass sponges are the oldest organisms on earth. It is even possible that glass sponges gave rise to all other multi-celled organisms!

    Grades: 6-12
  • Horseshoe Crabs | Big Pacific: Mysterious

    Horseshoe crabs are considered living fossils because they have changed so little in the 450 million years that they have been around. A horseshoe crab's hard outer shell tends to mask its true identity—the arthropods are related to spiders and scorpions. They live in shallow, sandy habitats that are threatened by coastal development and over-fishing, so conservation efforts in Hong Kong offer hope by sheltering juveniles through their vulnerable moulting process.

    Grades: 6-12
  • A Pufferfish's Masterpiece | Big Pacific: Mysterious

    In 1995, dovers disovered incredibly intricate sand circles scattered across the sea floor of the Amami Oshima region of Japan. The artist of these circles was a mystery for years, until it was revealed as the white-spotted pufferfish. Watch the pufferfish's intricate handiwork, as the three inch long fish shovels and moves sand into a circle that eventually reaches six feet in diameter. Once complete, the reason for the unusual design is clear; the circle is used to attract a female for mating and, if successful, serves as a nest for developing eggs.

  • Redwoods and Climate Change

    In this video from QUEST produced by KQED, follow a group of UC Berkeley scientists to the top of a 320-foot redwood in Mendocino County. See how scientists are trying to predict how the remaining redwoods and their descendants might fare in the face of climate change in the decades to come.

  • Urban Habitat: Biodiversity in Our Cities: Video | Nature Works Everywhere

    In this video, designed to accompany the Habitats and Pollinators Garden Activity Guide, students learn that a garden is a mini-urban ecosystem that can support the health of the entire urban environment.

    Grades: 3-12
  • Habitats and Pollinators: Garden Activity Guide | Nature Works Everywhere

    In this lesson plan and activity, students learn how the garden provides habitat for a variety of different animal species. Through making observations and collecting data, students determine which species inhabit the garden (especially pollinators), investigate relationships among them, and identify factors that may affect them.
