The transfer of heat is one of the fundamentals of scientific inquiry. Using numerous examples of how heat transfer is used in everyday life, this program takes students on a journey through the mechanisms and practicalities of heat transfer, clearly explaining the mechanisms of conduction, convection, and radiation and introducing the concept of thermal capacity of an object.

Investigates both saltwater and freshwater biomes. Explores how ocean temperature, salinity, and depth affect the enormous diversity of marine life. Covers the intertidal, neritic, and open ocean zones and their characteristics. Also examines estuaries and freshwater biomes such as streams, lakes, and ponds. Defines terms and concepts, and reviews content before a quiz.
The Arctic Sea Ice, a plate of ice roughly the size of Europe, is disappearing. Explores, with the company of scientists, the fabled Northwest Passage. Provides an overview of how polar bears, seals, and arctic birds are struggling to adapt to the rising temperature and their shrinking terrain. But beyond the wildlife, there are concerns about the effect the melting ice cap has on human life.
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.
There are millions of different types of animals on Earth, ranging from simple animals, such as sponges and worms, to more complex animals. Students focus on complex animals, specifically the major vertebrate groups: fishes, amphibians, reptiles, birds, and mammals. Specific examples of vertebrates are shown to illustrate the different characteristics of complex animals. Important terminology includes: vertebrae, backbone, gills, ectoderm, fins, metamorphosis, eggs, scales, feathers, and endotherm.
Offers a look at what kind of information satellites provide about our world. Satellite imagery has multiple uses: showing crops and pests, monitoring weather in all its forms, following forest fires and air pollutants, and more. Imagery notes climate changes, the ozone layer, and temperature of many things--all designed to predict and protect. These sensors present unusual windows to our world.
Explains the characteristics of plankton and its two types: phytoplankton and zooplankton. Animation shows where plankton flourish and what they need to reproduce. Notes the importance of sunlight, the thermocline, and moderate temperatures for plankton to "bloom." Stresses that without plankton, sea life would vanish.
Six researchers share 60-second stories about organisms that may be gone, but not forgotten. Researchers and scientists study these stories to get a better understanding of the complexities of life on Earth. Part of the "Shelf Life" series.
Corals have been devastated by the past few years of intense ocean heat. However, coral scientists are getting closer to understanding what makes certain species of coral able to withstand high temperatures. Part of the "Coral Comeback" series.
Canada's coastal forest is part of an ancient forest system of redwood, spruce, and cedar trees. It is also home to some of the largest aggregations of top predators in North America. The trees of this forest are huge, and forest productivity here rivals even some of the world's biggest tropical rain forests. Part of the "Nature's Microworlds" series.
A solution is a homogeneous mixture of two or more substances. It contains a solute and and solvent. Solubility is the maximum quantity of a solute that can be dissolved in a given amount of solvent at a specified temperature. Other topics covered include concentration, Raoult's law, colligative properties, and non-ideal behavior. Part of the "Chemistry" series.
The Galapagos Islands are home to a myriad of bizarre and unique creatures that are endemic to these islands, but how did they get here? What is the key to these extraordinary islands that allows them to thrive? In this episode, host Steve Backshall reveals the secret to life here. Part of the "Nature's Microworlds" series.
Viewers take a trip above the Earth’s atmosphere to learn about weather around the world. Students will come to understand the relationship between water, air, heat, and weather. The terms atmosphere, condensation, evaporation, and precipitation are explained through animated diagrams. This program also discusses meteorologists and the instruments they use to predict weather. Part of the Real World Science series.
In this episode, host Steve Backshall lifts the lid on an incredible world of intricate relationships and unexpected hardships in the Amazon rain forest. He explores the way that the jungle's inhabitants interact and reveals a hidden secret that might just be what keeps the whole place alive. Part of the "Nature's Microworlds" series.
Journey to the Scottish Highlands, home to some of the most iconic British wildlife. Since the Ice Age, the Highland landscape has undergone a transformation from dense forest to large areas of open space, and the wildlife there needs both of these habitats to thrive. Part of the "Nature's Microworlds" series.
Journey through the marine ecosystem of Monterey Bay, California, where a giant kelp forest hosts one of the most diverse marine ecologies in the world. The secret to the balance of this ecosystem is a keystone species: the sea otter. Part of the "Nature's Microworlds" series.
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.
NASCAR tires are filled with nitrogen to help protect against heat caused by friction. Friction also increases the air pressure in tires, and NASCAR drivers don't want a tire to blowout during a race. The use of nitrogen helps the crew predict how hot the tires will get. Part of "The Science of Speed" series.
In this episode, host Steve Backshall conducts an investigation into what makes the Okavango such a diverse place. The Okavango Delta is a vast inland river delta in northern Botswana. It's known for its sprawling grassy plains, which flood seasonally, becoming a lush animal habitat. Part of the "Nature's Microworlds" series.
Homeostasis refers to the body’s ability to maintain a stable internal environment, and maintaining homeostasis requires that the body continuously monitors its internal conditions. From body temperature to blood pressure to levels of certain nutrients, each physiological condition has a particular set point. Topics covered include homeostasis, negative feedback loop, nervous system, endocrine system, digestive system, excretory system, musculoskeletal system, and the immune system. Part of the "Biology" series.
