Students explore the characteristics of fluids. Some topics they study include pressure and its impact on the behavior of fluids, Bernoulli’s and Pascal’s principles, and density and its effect on buoyancy. Additional concepts and terminology discussed include: hydraulic devices, particles, differences in pressure, air pressure, and buoyant force.
Drawing upon the American Geological Institute's huge geoscientific archive of information, this segment explores the hydrosphere and the atmosphere. It also covers their formation and components, the water cycle, geological evidence of past climate change, extreme weather, and the future of the fluid spheres. Part of the "Visions of Earth" series.
Host Alex Dainis discusses GFP (Green Fluorescent Protein), and its importance in scientific studies. GFP is a green fluorescent protein found in jellyfish. Scientists use GFP in biology to mark particular genes in various experiments, and it provides a direct look into the inner workings of cells.
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.

The immune system defends the body from pathogens that cause disease. Scientists have been able to develop vaccines to prevent the spread of deadly diseases. They continue to research new vaccines and pathways to eradicate potentially harmful viruses. Part of the "Real World Science" series.
Access to safe drinking water is a global problem for nearly a billion people. For approximately 200 million people, many in Africa, high levels of naturally occurring fluoride in the water cause disfiguring and debilitating dental and skeletal disease. University of Oklahoma environmental scientist Laura Brunson is back from Ethiopia where, with support from the National Science Foundation, she’s developing fluoride filtering devices that use inexpensive materials readily available right there in the villages.
Deeply explores the structure of both plant and animal cells. Demonstrates the different types of cells, their components, and their functions
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.
The decade saw The Great War, The Flu Epidemic and the Titanic disaster. Ten years into the 20th Century and the world is grappling with some serious growing pains. In a decade racked by conflict, there were inventions that made the world both safer and infinitely more dangerous. Featured inventions include: the parachute, the gas mask, the toaster, the Tommy Gun, and sonar.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko bids farewell to Totemie. As promised, he gives Mei Li's stone and Alarick's flute. She in turn gives him a present that he may only open when he arrives at his destination. One morning, he sees the coast of his land after battling through a tornado! When he gets to shore, he opens Totemie's gift and finds not only her bracelet, but also Mei-Lei's stone and Alarick's flute and realizes that the greatest gift has been meeting his new friends.
The jaguar says llama wants to enter his house, but he doesn't want to let her in because she is sick. Apparently she has the swine flu, and he thinks she wants to infect him. Some audience members defend the jaguar and the llama. Llama explains that the house where the jaguar lives is her house and his uncleanliness has made her sick. After hearing the advices from the fleas, Kaka, and Ludovico, Jaguar promises to change his hygiene habits and apologizes to the llama for his behavior and promises to take care of her.
What happens to the stuff flushed down a drain? How do velocity and friction factor into this system? Get down and dirty to see how the sewer system relies on these elements of force. The experts develop tracking gadgets that journey through the sewer system hot on the trail of the flushed materials. Part of the "Break It Down" series.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, it is night time and Moko is watching the shooting stars from Totemie's village and is remembering how he once thought that a lady blew the stars in the sky from the embers of her bonfire. And suddenly, an immense star, a huge ball of fire, appears from the sky and falls to the depths of the forest. Totemie and Moko take off to see where the meteorite has landed and discover that a huge flaming rock has made a hole the size of a volcano's crater in the ground and is setting fire to the forest around it. Totemie is scared that the sky is angry and Moko, who remembers Mei Li begins to dance like she did while playing Alarick's flute. It begins to rain and slowly the flames die down. Moko thinks that the clouds must have seen him dance and heard his flute and come to save his new friend's land.
Draws on documentary and archival footage, 3-D and 2-D animations, and high-tech imaging to investigate a variety of virological topics: the nature of pandemics as illustrated by the SARS outbreak in China; genetic sequencing of Spanish influenza from exhumed tissue of a century-old corpse; how animal viruses jump the species barrier; the dissection of live viruses in a biosafety level-4 lab; the work of an Ebola research team in Gabon; the discovery of mimivirus; applications of Onyx-015, a genetically engineered adenovirus; and more. Features Vincent A. Fischetti of The Rockefeller University, Jeffery Taubenberger of the Armed Forces Institute of Pathology, Y. Guan of The University of Hong Kong, Didier Raoult of the French National Center for Scientific Research, and other leading virus specialists.
Sherlock Olmos decides to dig deeper into dark corner of this great house to investigate the suspicious behavior of some chemical elements. The exchange of electrons and the characteristics of hydrogen, fluorine gas, and the noble gases are the primary subjects of his investigation. Part of Chemistry: Solved by Sherlock Olmos Series.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the measurements of the International System of Units (SI). Part of the Science Video Vocab series.
Shows the crucial part water plays in the body's functioning and the system for keeping it in balance. Drinking, sweating, and breathing are covered. The urinary tract is analyzed in detail, with particular attention to the functioning of the kidneys.
