AQUACULTURE - ADVANCES IN FISH FARMING |
Print Guide |
|
Aquaculture is one of the newest industries on the planet and is making a big splash in the state of Florida. There are over 210 farmed aquatic plant and animal species reported world-wide. Florida’s warm waters encourage faster growth of certain species such as mollusks and cobia fish. This new industry is also responsible for job growth needed for the development of specialized equipment, ongoing research and aquaculture farms. RT @ 15:00

METEOROLOGY, THE MYSTERY OF CLOUDS |
Print Guide |
|
Meteorologists studying clouds in Europe tell us that by learning about the microphysical processes that occur naturally in clouds, researchers gain new fundamental knowledge that can help improve weather and climate forecast models. This issue explores known, speculated and unknown information about cloud structures and mechanisms. The newest technology and how it works is also presented. RT @ 15:00

THE BANDED STILT - A WETLAND SURVIVOR
|
Print Guide
|
|
When conditions in the Australian outback are right, a distant shoreline visitor, the Banded Stilt arrives by the thousands to breed. The mystery behind this behavior was finally documented when Cyclone Bobby started a chain reaction by flooding a dry salt lake in the outback. The saturated lake supports a variety of algae, bacteria, and the all important brine shrimp. In this issue, students see how animal life, microscopic organisms and the ecosystem are interconnected for the survival of all three. RT @ 15:00

WIND POWER - A RENEWABLE ENERGY SOURCE |
Print Guide |
|
Fossil fuels have long been the world’s energy source, but it wasn’t always that way. Ancient Near Eastern cultures developed the first known wind mills for drawing water and grinding grains into flour. The modern three-blade, computer-controlled Wind Turbine does what all wind turbines have always done – harness the energy from the earth’s constant flow of air. This program explores wind power alternative energy production in today’s oil-dependent economy - how it works and the environmental factors that scientists are researching. RT @ 15:00

THE AMAZING RED CRAB OF CHRISTMAS ISLAND
|
Print Guide
|
|
Christmas Island, discovered December 25, 1643, is just a spec of land in the Indian Ocean. The annual red crab migration at the beginning of the rainy season, however, is so massive it can be seen from the air. It has been named a wonder of the natural world. This program follows this terrestrial arthropod from its rainforest burrow, across dangerous landscape to the ocean to mate. RT @ 12:00 |

DESERT SANDS - DUST FROM AFRICA |
Print Guide |
|
Sand particles from the Sahara desert have long been known to travel across the Atlantic Ocean and southward to the Amazon rain forest in accumulations called ‘dust carpets’. Water molecules adhere to the sand particles to form droplets that accumulate into clouds. The mineral-enriched water falls to earth in a downpour thereby nourishing the flora below. Mongolian desert dust carpets present problems for ecosystems upon which it falls. This issue explores the science behind the storms and their impact on global climate. RT @ 15:00 |

AGRICULTURE - FEEDING A HUNGRY PLANET |
Print Guide |
|
Scientists throughout the world are researching and implementing sustainable food production systems. Key concepts that underline this vital research are ecosystem preservation and natural resource conservation. Food production systems touch nearly every aspect of life – from farms and industrial processing plants to markets, grocery stores and the dinner table. Students will learn about the future sustainable ‘food cycle’. RT @ 15:00

PROPULSION - TECHNOLOGICAL ADVANCES |
Print Guide
|
|
The concept of ‘propulsive thrust to move objects over large distances’ is ancient. Yet, the technology to move an automobile forward or a rocket into space was invented less than two centuries ago. The invention of the solid fuel propulsion system combined with Newton’s Third Law is the simplistic basis for modern rocketry. This program reviews the history of propulsion and explores its use as a viable energy source of the future. RT @ 15:00
