Explains what is normal for boys and girls at puberty: the biological facts of physical maturation, the timeline for growth for both sexes, the normal feelings of self-consciousness, the need for good personal hygiene, why mood swings happen, and preparation of the body for human sexuality and reproduction.

What's a trippy shape? It defies the normal principles of geometry and goes beyond three dimensions. MIT scientists explain, knit, and 3D-print their way through trippy shapes. Part of the "Science Out Loud" series.
When Brandon was 10 he was diagnosed with psoriasis. At first, he was very ashamed due to the visible patches on his skin. However, five years after his diagnosis, with adequate treatment, he lives with the disease and has a normal life.
The body's best offense against microorganisms is its immune system. But what is it and how does it work? Why does it sometimes work against us? Discusses the non-specific (skin, tears, saliva, mucus, stomach acid) and specific (lymphatic system, spleen, thymus, bone marrow) defenses that keeps us healthy. Describes some autoimmune diseases and various marrow-produced cells.
Is a sixth mass extinction on the horizon? Dr. Anthony Barnosky and Kaitlin Maguire travel to the John Day Fossil Beds National Monument to find, collect, and date fossils. They have determined that the rate at which animals are going extinct today is much faster than normal.
Travel to the Namib Desert and discover the key characters of some of the ingenious adaptations that allow animals to thrive in this harsh environment. The secret to life in this unique ecosystem lies in the distribution of airborne water and food sources. Part of the "Nature's Microworlds" series.
Part of the "Green Careers" series. Provides an inside look at an organic farm and an organic retail store. Discusses the daily challenges and rewards of working in this field. Organic farming includes a wide range of jobs in production, marketing, and distribution. Jobs profiled include the following: farm manager, retail sales manager, and organic produce buyer.
Gives basic first-aid techniques to help an injured dog in the first critical moments after a medical emergency occurs until the dog can be transported to a veterinarian. Covers: what's normal for my dog, scene safety, muzzles, rescue breathing, CPR, choking, fractures, car accidents, shock, poisoning, snakebites and more. Lists what to include in a pet first-aid kit. Recommended by ASPCA.
Gives basic first-aid techniques to help an injured cat in the first critical moments after a medical emergency occurs until the cat can be transported to a veterinarian. Covers: what's normal for my cat, scene safety, restraints, rescue breathing, CPR, choking, car accidents, poisoning, burns, heatstroke and more. Lists what to include in a pet first-aid kit. Recommended by ASPCA.
Biologists and anthropologists at The Field Museum are studying weaponry to discover the distribution of Central Pacific sharks from more than 100 years ago. Various weapons in the collection have the unique feature of being studded with shark teeth. In this episode, host Emily Graslie discusses the findings and implications from examining the weapons in the collection. Part of "The Brain Scoop" series.
Locked-in syndrome is a condition in which people with normal cognitive brain activity suffer severe paralysis, often from injuries or an illness such as Lou Gehrig’s disease. Boston University neuroscientist Frank Guenther conducts research on how brain regions interact, with the hope of melding mind and machine, and ultimately making life much better for people with locked-in syndrome.
This two-part video introduces the different types of bridges. In part one, simple beam and arch bridges are introduced. The design of each bridge is shown schematically along with the load distribution. The advantages and limitations of each type of bridge is also discussed. Technical concepts covered include tension, compression, bending, span, force balances, material selection, and beam/cable design. Part of "Bridge Design (and Destruction)" series.
British naturalists Charles Darwin and Alfred Russel Wallace both set out on epic adventures to study various species and their development. They gathered evidence on the variation among individual members of a species, the relationships among species, and the patterns of geographic distribution across many species. Based on such evidence, they independently came to the same revolutionary conclusions: species change over time by means of natural selection, and species descend from other species.
Psychiatrist and author Dr. Norman Doidge travels across North America to meet some of the pioneering researchers who made revolutionary discoveries about the plasticity of the human brain. He also visits with people, once thought to have had incurable brain injuries, who are now living normal lives. Known in scientific circles as "neuroplasticity," this radical new approach to the brain provides an incredible way to bring the human brain back to life.
One of the areas that is most sensitive to climatic change is human health. Climate change affects human health in numerous ways. Some are immediate, and others may not manifest until future generations inhabit earth. Global areas have already begun to suffer the effects of ecosystem alterations and limited water sources. These situations also impact crop production and food distribution. Researchers also predict an increase in the number of displaced persons as the planet warms and sea levels begin to rise. Chapter 10 of Air: Climate Change Series.
This two-part video introduces the different types of bridges. In part two, truss and suspension bridges are introduced. The design of each bridge is shown schematically along with the load distribution. The advantages and limitations of each type of bridge is also discussed. Technical concepts covered include tension, compression, bending, span, force balances, material selection, and beam/cable design. Part of "Bridge Design (and Destruction)" series.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Ms. Frizzle turns the class into water so they can experience the town's water system firsthand. Not everything goes as planned, though, when they realize that Arnold has left Ms. Frizzle's magic keys in the girl's bathroom at the school. How will they turn back to normal this time?
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the Cyclops crashes into the bottom of the pond and discovers an ooze populated by bacteria. After gathering some, the Micronauts begin to investigate the chemical method the bacteria uses to decompose organic material. In the end, the bacterial also helps the crew escape the bottom of the pond so they can continue to explore. Part 5 of the Microscopic Monsters Series.
