Shows how the cerebellum coordinates muscle activity and how position sensors in the muscles and joints and the balancing mechanism of the inner ear function. The motions of a water-skier show the physical, interconnected structure of muscles, joints, and organs. The role of joints is explained, and a look at the interior of a human knee shows clearly how lubricating fluid is produced.

Charles Drew set a standard of excellence unparalleled by most of his white contemporaries. In 1943, his distinction in his profession was recognized when he became the first black surgeon to serve as an examiner on the American Board of Surgery. Despite the prejudices of American society in the first half of the 20th century, Charles Drew persevered in his practice and was never afraid to stand up for his beliefs and racial equality.
What happens to the body during sleep? Explores the mystery of REM sleep, shows a computer display of the waves that sweep across the brain during sleep, and presents extraordinary footage of a cat "acting out" its dreams. The analogy of comparing sleep to a ship on automatic pilot graphically illustrates how some functions must and do continue while the conscious brain is asleep.
The team settles in for a month on the Great Barrier Reef, the largest reef in the world. One scientist is studying sharks, while another group explores the northern portion of the reef. The team discovers bleaching and severe die-off among corals at the reef. Part of the "Global Reef Expedition" series.
Recapitulates and reviews the principal messages of the curriculum as it summarizes the functions and designs of the body's major systems and organs and the methods by which they interact. NOTE: Contains some nudity.
In this episode, citizen scientists are using a wide array of technology applications to collect data on environmental concerns. A group of individuals are using an app to count birds, which generates data on a changing climate. Surfers, using smart tech, track ocean acidification and coastal temperatures. Other projects include collecting data on the migration of monarch butterflies and surveying horseshoe crab populations. In Uganda, World Bank economists and local partners generate data for sustainable development. Part of "The Crowd and the Cloud" series.
Demonstrates how a heart actually functions as two pumps in one. Scenes at an amusement park show the effects of activity on the heart. Scenes of the internal heart are matched with still drawings and animations that depict the heart's valves, muscle, and pacemaker. The effects of diet and exercise on the heart are mentioned.
In this episode, citizens and scientists partner to gather data on many environmental concerns around the world. A group of citizen scientists track air and water pollution at fracking sites in Wyoming and 5 other states. They use simple but science-based techniques developed by the “Bucket Brigade.” Volunteers from Trout Unlimited monitor water quality regularly, generating baseline data that will prove invaluable in the event of future pollution events. Community members connected with professional researchers explore Flint’s drinking water crisis and help other cities test their water quality. In China, citizens use government data and a unique mobile app to report environmental crimes. Part of "The Crowd and the Cloud" series.
In this episode, groups of citizen scientists use apps and maps to help researchers gather data about medical conditions. Sensors on asthma inhalers generate real-time maps of environmental dangers to help patients and physicians in Louisville, Kentucky. In West Oakland, California, citizens confront air pollution and rising asthma rates by collecting traffic data. Citizen scientists are fighting mosquito-borne diseases with apps and crowd-sourced data in Barcelona, Houston, and New Orleans. Part of "The Crowd and the Cloud" series.
In this episode, groups of citizen scientists use mobile technology to help save lives. Volunteers across North America measure precipitation, and their data is used by emergency managers to issue warnings during extreme weather conditions. In India, a phone app helps officials alert communities about killer heat waves. Citizen scientists also help collect data about Alzheimer's disease. They hope their data will aid the research process and lead to a cure. Part of "The Crowd and the Cloud" series.
Figure 2.7 (OpenStax, Biology 2e) caption: Bohr diagrams indicate how many electrons fill each principal shell. Group 18 elements (helium, neon, and argon) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration. Elements in other groups have partially filled valence shells and gain or lose electrons to achieve a stable electron configuration.

One of the fifteen parts of the "Farm to Market" series. Begins with a trip to the dairy farm to see how cows are cared for and fed. Demonstrates how the cows are milked by machine and how the milk is processed and transported. Also shows how milk is made into cheese and butter.
One of the fifteen parts of the "Farm to Market" series. Bees gather nectar from flowers and use it to make honey. Demonstrates bee behavior, beekeeping, honey harvest, and packaging. Follows the process from start to finish, including footage of bees inside their hive.
One day, microbes will eliminate dirt and garbage, filter exhaust systems, and help make self-cleaning clothing possible. Takes viewers on a global journey-from the U.S. to Iceland, Sweden, India, China, Senegal, and Australia-to meet the world's leading specialists in bacteriology and to discover the incredible abilities of the microscopic life-forms they study. Employs state-of-the-art imaging technology and animation to illustrate how bacteria have learned to adapt to harsh environments and how they can be found in a vast array of human-made products and materials, including medicines, pesticides, plastics, solvents, and even electroacoustic speakers.
One of the fifteen parts of the "Farm to Market" series. Explores the journey this popular fiber takes from the time it is a small green plant through harvest, ginning, spinning, weaving, and sewing.
One of the fifteen parts of the "Farm to Market" series. Just like fruit and vegetables, flowers are raised commercially on farms. Shows how flowers, such as roses, orchids, anthuriums, and carnations, are raised outdoors and in greenhouses. Also visits a wholesale flower market to see where merchants go to buy flowers for their stores.
One of the fifteen parts of the "Farm to Market" series. Many fruits are enjoyed fresh, right off the tree. Visits a variety of farms to see how different fruits are grown, harvested, and prepared for market. Provides an overview of processes by which fruits are preserved, including canning and drying.
One of the fifteen parts of the "Farm to Market" series. Almonds, walnuts, pistachios, pecans, chestnuts, and macadamia nuts are grown and harvested in different ways. Provides an overview of various nut farms and follows nuts from the orchard to the market.
Part of the "Green Careers" series. Introduces job opportunities in recycling, including collection, transportation, receiving and sorting, disassembly, handling hazardous materials, scheduling, operations, and plant management. Recycling provides opportunities for young people to start with a temporary or part-time job, then move up to supervisory and management responsibilities. Jobs profiled include the following: e-waste entrepreneur, plant manager, biofuel coordinator, and truck driver.
One of the fifteen parts of the "Farm to Market" series. Reveals the process behind one of the world's most popular treats. Demonstrates how chocolate begins as cacao beans growing on the cacao plant. The journey continues with the processing of cacao seeds into cocoa, which is then transformed into delicious chocolate products.
