In a decade dominated by the Great Depression, the inventors of the 1930s were desperately trying to make a living. They come up with some simple yet ingenious inventions that are still practical necessities in our fast-paced life. Featured inventions include: the helicopter, xerography, the parking meter, the walkie talkie, and the electric guitar.

Students will learn how to measure length and distance using common tools. Concepts and terminology include metric ruler, meter, centimeter, and kilometer.
Students explore the relationship between observations and measuring things in science. Specific ways of measuring length, mass, volume, and temperature are demonstrated using tools common to the classroom. Other terminology includes unit of measurement, meter stick, metric ruler, balance, graduated cylinder, and thermometer.
Nano expert Nicole Steinmetz from Case Western Reserve University discusses naturally occurring nanomaterials. Part of the “Ask a Scientist” series.
Students will explore the physical and chemical properties of matter. Special attention is paid to the method by which matter is measured. Length, mass, weight and volume of common everyday matter is discussed. Other topics covered include the metric system, meter, kilogram, gram, liter, water displacement, and density.
The Solar Decathlon is an annual event where collegiate teams design, build, and operate solar-powered homes. In 2011, it was held on the Mall in Washington D.C. Twenty solar-powered homes were sprawled across the mall’s west end, transforming it from a park into something that resembled a quirky housing development.
Host Jeff Corwin races to the west coast to uncover the secrets behind a marine mammal disaster. Thousands of weak sea lion pups have been stranded along beaches throughout Southern California. Jeff is on a mission of research, rescue, and recovery.
Hanna and Olli feel sad and disappointed when they find out a small neighborhood park is being dug up to make way for a parking lot. They visit it one last time, and an old oak tree unexpectedly gives them some hope for the future. Part of the "My Little Planet" series.
Examines the nuclear disaster that followed an earthquake and tsunami that rocked Japan on March 11, 2011. That day, Japan was hit with the fifth strongest earthquake ever recorded. The earthquake was followed by a tsunami which caused a nuclear disaster at Fukushima Nuclear Power Plant. This documentary details the chain of errors and oversights that led to the largest nuclear accident since Chernobyl.
This creature was found 1,800 feet deep in the ocean. It’s called a basket star. This extraordinary invertebrate has a mass of twisting and turning arms that can measure a meter long. Each branch has tiny sharp hooks allowing the creature to capture prey, and it feasts mainly on zooplankton. Basket stars are able to grow their limbs back if they are broken or chopped off by predators. Part of the "Creatures of the Deep" series.
Long necks gave sauropods a huge advantage when it came to food. This benefit also enabled them to become the biggest terrestrial animals of all time. Part of the “Eons” series.
Visualize the gravitational force that two mass spheres exert on each other. Move spheres in meters, change mass in kilograms, and observe changes to the gravitational forces that m1 and m2 exert on each other.

Gas hydrates are a significant potential energy source occurring in ocean-floor sediments at water depths greater than 500 meters. The USGS (US Geological Survey) operates a gas hydrates laboratory on its Menlo Park campus. USGS geophysicists Laura Stern and Steve Kirby detail how they study and create gas hydrates in their super-cooled lab.
Marine debris comes from many different sources and enters the ocean in many ways. Intentional littering and dumping are big causes. Sometimes the trash goes directly into the ocean, and sometimes marine debris is indirectly generated in a city hundreds of miles from the ocean. When someone litters on the street or parking lot, rainwater can move the trash into storm drains that empty into streams, rivers, and other bodies of water. Improper or careless waste disposal also contributes to this environmental concern. Part of the "Trash Talk" series.
The first thing a baby giraffe experiences after being born is a two-meter fall straight down to the ground. But within an hour, it’s standing, walking, and nursing on its own. A blue whale calf, after nearly a year growing inside mom, can swim to the surface moments after being born. Human babies on the other hand are born unable to move or eat on their own. If humans are so smart, why are human babies so unsmart? Some may think it’s all about head size, but the real science is more complex. Part of the “It’s Okay to Be Smart” series.
An early exploration (2015) into how to make a sim accessible has taken place for Capacitor Lab Basics. The sim is keyboard navigable with some auditory descriptions when using 'Forms' mode with a screen reader. We are working on updating the content and the interactions, so that the simulation can be accessed by a screen reader in any mode. This prototype has been tested with NVDA and Firefox.
Does anyone ever think about the four pounds of garbage they produce every day? Get down to the nitty-gritty and discover the delicate ecosystem of a landfill, including the potentially harmful byproduct methane gas. Viewers follow the stinky trail from curb to dump to uncover the fate of trash and the science behind decomposition. Part of the "Break It Down" series.
From end to end, its forelimbs alone measured an incredible 2.4 meters long and were tipped with big, comma-shaped claws. But other than its bizarre arms, very little material from this dinosaur had been found: no skull, no feet. Scientists were unable to create a full picture of this dinosaur until they began exploring quarries in 2006 and 2009. Part of the "Eons" series.
Explores the pros and cons of building the Three Gorges Dam across the Yangzi River in China to control floods and generate electricity. Expected to be completed in 2009, it will be the biggest dam ever built anywhere in the world. Two million people will be displaced and 1,400 towns and villages will be flooded. Asks the question: Are the potential benefits worth the costs?
Host Steve Backshall examines what is by far the largest ecosystem on the planet: the deep sea. It contains some of the most extraordinary and bizarre life forms. There is even life on the deep seabed, where armies of sea urchins, giant wood louse, and deep sea crabs feed from a thick layer of sediment. Part of the "Nature's Microworlds" series.
