An inspired story of love, dedication and the remarkable bond between humans and animals, this film documents orphaned orangutans and elephants and the extraordinary people who rescue and raise them—saving endangered species one life at a time. Narrated by Academy Award® winner Morgan Freeman (March of the Penguins), this heartwarming adventure transports viewers into the lush rainforests of Borneo with world-renowned primatologist Dr. Birute...

Yakka Dee! is a show that encourages children to talk. Each episode focuses on one word.

Many factories around the world use perfluorinated chemicals to make everyday products. Due to their chemical stability, these compounds are “forever chemicals” They do not break down. Even worse, they can build up inside the human body and cause health problems, including cancer, and compromise the immune system. Companies have routinely dismissed campaigners who insist that cancer cases have risen close tofactories which use perfluorinated chemicals....

From Peru, where the mineral is extracted, all the way to France, where the metal is refined, lead pollutes the earth, the rivers, food supplies, and local people. Despite being banned in numerous products including fuel, paints and the manufacture of pipes, lead is still often used in buildings, weapon development, jewellery and even in batteries. At Évin-Malmaison, France, lead from refineries has contaminated the earth underneath various schools,...

Mining is one of the oldest applications of practical geology. Find out how metals are classified and how most are associated with igneous and metamorphic deposits. Some metals, like gold, can be mined in a pure—"native"—state that requires little processing. Discover how and where to go prospecting for gold, using the panning process perfected by the Forty-Niners in California.

Visit the beach with a geologist's eyes and see how the interaction of waves, ocean currents, and winds lead to the ebb and flow of sediments and blending of landforms. Consider the four types of waves and what they reveal about the ocean floor just offshore. Also, zero in on individual grains of sand, identifying their minerals and tracing their origin. Reflect on why beaches are sandy at all.

Metamorphic rocks form under conditions halfway between those of sedimentary and igneous rocks. A good analogy is the process of glacier formation that turns snow into dense, interlocking crystals of ice. Focus on foliated metamorphic rocks, such as slate and gneiss, which have lineation patterns. Geologists can read these patterns to reconstruct ancient mountain ranges and plate boundaries.

Soil may be the most important geologic resource on the planet. Discover how geologists classify soils, focusing on the concept of soil horizons, which are distinct layers that often vary in composition, color, and texture. Analyze how this cross section, which signals soil fertility, differs depending on the type of biome. Learn how soils form and how easily they are destroyed by erosion.

Based on the beloved young adult novel. A young man (Brenton Thwaites), who lives in a seemingly ideal world, must escape after discovering the deadly truths of his community’s secret past.
