Part of the animated "Johan, the Young Scientist" series. While waiting for his rechargeable batteries to charge up, Johan discovers in ScienScape that electricity is generated by cranking up a dynamo. Professor Hoo then sends him, Ani, and Moki to find how different power stations use different methods of generating electricity.

The evolution of the arms, legs, necks, and lungs of the human body can be traced to a fish that lumbered onto land some 375 million years ago. The genetic legacy of this creature can be seen today in human DNA, including the genes used to build hands and limbs. Part of the “Your Inner Fish” series. Please note this title shows corpses in anatomy labs and contains mature themes.
This episode highlights a group of scientists that brew lava and blow it up to better understand volcanoes. Other segments include rice plants that reproduce from clones, an energy-efficient way to stay warm, and Maria's effects on Puerto Rico's watershed and forests. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
The rock pocket mouse is a living example of Darwin's process of natural selection. Not only is evolution happening right now everywhere around us, but adaptive changes can occur in a population with remarkable speed. This speed is essential if you're a desert mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. Features Dr. Michael Nachman, whose work in the field and in the lab has quantified the selective pressure of predators and identified the genes involved in adaptation. From ecosystem to molecules, pocket mice show the viewers how random changes in the genome can take many paths to the same adaptation-a colored coat that hides them from predators.
Students explore the many important uses of electricity. The nature of electricity and the formation of electric current are highlighted. Special attention is given to safety and electricity. Concepts and terminology include charge, current, lightning, battery, generator, and wiring.
In this episode, host Dianna Cowern conducts and explains 5 scary physics experiments. She uses dry ice, a Van de Graaff generator, and a plasma ball to demonstrate a few principles of physics. Part of the "Physics Girl" series.
Join the Amoeba Sisters as they explain gene and chromosome mutations and explore the significance of these changes. A mutation is a change that occurs in a DNA sequence, either due to mistakes when the DNA is copied or as a result of environmental factors. Part of "The Amoeba Sisters" series.
Follows scientists as they explore the mysteries of attraction, natural selection, and survival of the fittest in the male animal kingdom. The scientists use unorthodox techniques and the latest technology to study how males in the animal kingdom achieve their main goal of passing their genes to the next generation. For some species in the animal kingdom, males will go to extremes to win a mate. They make music, fight, overdress, and even agree to be eaten alive to ensure survival of the fittest.
Science laboratories present a whole range of potential hazards to people's health and well-being, and it is critical that both teachers and students are fully aware of their responsibilities to ensure the learning environment is kept safe at all times. Aims at viewers who are not new to science laboratories. Covers a range of safety areas, including general safety in these laboratories and specific areas of potential risk in chemistry, biology, and physics labs.
The tragic 2013-2015 Ebola outbreak in West Africa shocked the world. Computational geneticist Pardis Sabeti and disease ecologist Lina Moses explain the science behind how this event became the largest Ebola outbreak in history. Part of the “Think Like a Scientist” series.
This video explores the mystery of why the traits of some offspring resemble their parents and others do not. The concept of heredity is discussed, as is the process by which genetic material is passed on from one generation to the next. Through colorful animations and vivid footage, students explore the key concepts concerning the inheritance of characteristics.
When facing complex issues, psychologists often break them down into their component parts, and then identify a key cause. This approach is called reductionism, and viewers explore the advantages and disadvantages of reductionism. Students are given a case study and asked to examine the utility of a reductionist approach. Part of the "Core Concepts in Psychology" series.
Part of the "Inside the Living Cell" series. Shows how DNA replicates; how copy errors occur and are subsequently corrected by repair enzymes; and how DNA is compressed into chromosomes, making mitosis and cell division possible. Provides an overview of DNA structure, replicating DNA, mutations that change the genetic code, proofreading and repair, and the stages of mitosis.
A new transmitter helps protect wireless data from hackers. Other features in this episode include bacteria using DNA to speed their evolution and a new next-generation water harvester that delivers fresh water from air. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
The world's nuclear power plants have generated an estimated 300,000 tons of high-level radioactive waste that must be safely stored for 100,000 years or more. Every year, they generate another 12,000 metric tons of high-level waste. Takes viewers deep into the Onkalo facility as it is being constructed and asks Onkalo representatives, scientists, theologians and others to address fundamental but challenging questions.
Ten thousand years ago, corn didn’t exist anywhere in the world, and until recently scientists argued vehemently about its origins. Today the crop is consumed voraciously by humans, by livestock, and as a major part of processed foods. So where did it come from? Evolutionary biologist Neil Losin tells the story of the genetic changes involved in the transformation of a wild grass called teosinte into corn. Evidence from genetics supports archeological findings pinpointing corn’s origins to a very particular time and place in Mexico.
Researchers hitch a ride with the Mexican Navy to visit the breathtakingly beautiful but critically endangered island habitat of Guadeloupe Island. Led by Drs. Borja Mila and Ellen Ketterson, the team sets out to collect some of the first modern data and genetic samples from the juncos found on the remote island, with the goal of learning the origins and evolutionary history of this mysterious species. What they find could have important implications for the future of this fascinating but imperiled population of juncos. Part of Ordinary Extraordinary Junco (Chapter 5).
Dr. Jeffrey Friedman shows how leptin rewires neural circuits, and how population studies may identify obesity genes. Part of the 2004 Howard Hughes Holiday Lecture Series
Students learn the process of weighing common objects. Concepts and terminology include matter, mass, weight, scale, and metric system.
Professor Lawrence Gilbert and his team at the University of Texas at Austin have discovered a population of tropical butterflies that exemplify "evolution in action," and a rare research opportunity. Gilbert says they may be witnessing a species of butterfly splitting into two different species. The stars of this research are the Heliconius butterflies, found in Central and South America. Despite the genetic similarities between the two groups of the butterflies, one group is showing a color preference during mating. With support from the National Science Foundation, Gilbert and his team are working to gain insights about genetics, behavior, ecology, and evolution.
