FORGOTTEN SENSE OF TOUCH |
Sample VIDEO
Print Guide |
 At some point in our lives we might meet a person who has lost one of their senses. Most often it will be one who has lost sight or hearing. Science and technology have been able to assist people with their loss of sight or hearing through corrective surgery or the use of an aid. But what is available for those who lose their sense of touch? Each day our sense of touch is put to the test. Whether it is testing water for a bath, holding a coffee mug, caressing a loved one or greeting someone with a handshake, we rely on touch. |

END OF THE DINOSAURS |
Sample VIDEO
Print Guide |
 Dinosaurs were the dominant land vertebrates for 140 million years. They filled many niches and competed with other organisms, such as mammals, for space in ecosystems. For years, scientists have predicted that the dinosaurs became extinct in a short period of time, the result of an extraterrestrial impact from a comet. However they did not have the evidence to support this theory.

PROTECTING EARTH'S ATMOSPHERE
|
Sample VIDEO

 Earth is the only planet known to support life. The primary reason is a mixture of different gases known as the atmosphere. These gases, along with the sun, warm our planet to an average temperature of 15 degrees Celsius. This delicate process is known as the Greenhouse Effect. Without it, the sun's energy would escape back into space leaving the Earth frozen. |

THE NATURE OF FIRE |
Sample VIDEO

 This program explores the elements necessary to create fire. The fire triangle consists of heat, fuel and oxygen. Firefighters demonstrate how to put out different types of fires, with a particularly dramatic example of why you should never put water on an oil fire. Firefighters show how using thermal imaging camera helps to identify the source of a fire. A gel containing water filled bubbles is shown protecting houses from burning.

DESERT: LAND OF EXTREMES
|
Sample VIDEO
Print Guide |
 Seventy percent of the Earth is covered with water, while 30 percent is land. Surprisingly, deserts cover nearly 20 percent of the Earth's land surface. When we think of deserts we tend to think picture vast areas of dry land with temperatures so high that only a cactus or a camel can tolerate the heat. However, deserts can be found all over the world, in tropical regions and on the backsides of mountains. Each desert is unique, but all share commonalities - they are dry, windy, arid lands with little annual rainfall.

A SCIENTIFIC LOOK AT THE SUN |
Sample VIDEO
Print Guide |
 Day after day the Sun shines in the sky, one of the constants in our lives. But, we know that the Sun has a life of its own and someday, like a living organism, it will die as well. Scientists can predict what the Sun's life will be like and what will happen billions of years into the future.

WATERY CREATURES: LIFE IN THE SEA |
Sample VIDEO
Print Guide |
 Oceans cover nearly seventy-five percent of the Earth's surface, with depths greater than land's highest mountains. Flowing with salts, minerals and dissolved gases, these waters allow sea life to thrive. Recently, oceanographers have journeyed into the ocean to learn more about the survival of many species. |
