THE SPINE: COMMAND CENTRAL |
Sample VIDEO
Print Guide |
 This issue of SCIENCE SCREEN REPORT provides a comprehensive look at the central nervous system. True-to-life animations demonstrate its components and how they work together to allow us to move. Students will also see how damage to the central nervous system can cause paralysis, and what scientists are doing to advance medical treatments in order to correct spinal cord injuries and cure paralysis. |

ANTS: OUR TINY NEIGHBORS |
Sample VIDEO
Print Guide |
 Ants have developed intricate behaviors and survival mechanisms that allow them to live in large, cooperative societies. This issue offers close-up views of ants at work as builders, farmers, biologists and chemists. It shows how they adapt to the needs of their environment, even by genetic means, and how collective instinct can be used to accomplish large tasks. Students will also learn how scientists are trying to help human farmers eliminate crop pests and disease by studying ants.

ELEMENTS OF NATURE
|
Sample VIDEO
Print Guide |
 Elements are the basic building blocks of everything. This report demonstrates the effects of some elements on the world around us, and how elements can be combined to serve our needs. The program also illustrates how early humans came to understand elemental properties and used them to make tools and fire. There are also animations of the atomic structure of some elements, along with information about how the atom was first conceived by Democritus, and the equipment scientists use today to “see” and to manipulate the atoms around us. |

ENERGY FOR LIFE |
Sample VIDEO
Print Guide |
 This edition of SCIENCE SCREEN REPORT examines how our bodies acquire and process energy through the oxygen we breathe and the glucose we obtain from nutrients. It explores two different physiological systems that work together in order to keep our bodies running efficiently. It demonstrates how the respiratory system processes oxygen that is used within our bodies, and explains the circulatory system and its internal transport of oxygen.

FUELS AND GASES
|
Sample VIDEO
Print Guide |
 This report looks at the composition and properties of gases and fuels. It demonstrates how our use of different gases relates to their weight, combustibility, and the degree to which they can be compressed or liquefied. The program discusses use of gas and other fossil fuels from ancient times to the present, and explains how scientists have made it possible for gases such as hydrogen to provide fuel for the future.

THE EVOLUTION OF PLANTS |
Sample VIDEO
Print Guide |
 This edition explores how plants evolved after moving from the sea millions of years ago. Students see how fern-like plants living on damp coasts in pre-historic times evolved into trees that are 300 feet tall. The program demonstrates the different ways plants evolved to obtain nutrients, as well as the variety of ways that plants propagate. Students will also come to understand the unique capabilities of some plants to withstand damage in fires and to ward off predators, and how scientists hope to use this knowledge to improve modern technologies.

THE SEARCH FOR BLACK HOLES |
Sample VIDEO
Print Guide |
 Black holes are one of the frontiers of physics. Their existence was only confirmed recently, and scientists are speculating about their properties and what black holes will teach us about the origin of the universe. This issue examines the history of physics, including the development of Newton’s Laws of Gravity and Einstein’s general theory of relativity which led to theories about black holes. The program also illustrates the equipment scientists used to uncover them and explores theories suggesting that black holes are portals to other universes or shortcuts in space-time travel. |
