Science

Stunning NASA and live footage combine with state-of-the-art animation to give students a clear understanding of the physical features that shape our earth. Terms like escarpment, plateau, butte, outlier, and atoll are shown in their natural states with examples highlighted on an animated globe. Learn the names of these landforms and where they are found.

The surface of the land has undergone many changes over its history. Water, rain, snow, and wind they all continually shape and form the Earth. Take students on a journey to discover how physical weathering, chemical weathering, and erosion occur. Identify that the destructive forces of erosion and weathering are slow processes that change the surface of the earth.

Part 1: Origins: Search for and discover the origin of today's animal life. Part 2: Life On the Move: When we think of animals, we think of movement. Surprisingly, the diverse and graceful ballet of movement may have started with a single group of creatures whose descendents were the first to harness the power of muscles and nerves.

Part 1: The First Hunter - The first animal to develop a head, eyes and a brain also pioneered a new way to survive: it would become Earth's first hunter. Dramatic new evidence points to an unlikely and oddly charismatic subject...the flatworm.

Part 1: The Conquerors: For hundreds of millions of years, animal life resided only in the oceans. And then, in one extraordinary event, something happened that enabled one group of animals to emerge from the sea. Follow scientists as they track how the shape of life transformed to create the animals that led the first successful land invasion and were the first to pioneer flight.

The Shape of Life tells the gripping and magnificent tale of the beginnings of all animal life.

Chronicles the historical development of the concept of an "element" from the ideas of ancient Greece through modern quantum theory. Viewers learn that scientists like Boyle, Dalton, and Lavoisier began to recognize patterns in the behavior of chemicals, they sought a unifying principle that would explain why different elements had different properties.

Join us as we investigate the links between chemistry and real life using the most successful arrangement of scientific data ever devised - the modern periodic table! This fascinating series reveals layer after layer of meaning contained in this simple table with dynamic graphics and exciting lab footage.

Students will see how the elements are arranged and underlying patterns are revealed. A dynamic tour of the groups that make up the table combined with lab footage allows viewers to see chemistry in action. Includes a look at some of the many patterns found in periods and groups of elements that combine to create the world around us.

Viewers will see that chemical bonds are the key to understanding how elements combine. The differences between ionic and covalent bonds are clearly presented using vivid graphics and dynamic footage. Students see how valence electrons interact among atoms to form compounds, and learn how simple Lewis structures can help describe how easily an element will react.

Explores the connection between the atomic structure of an element and its properties. Students see how the behavior of the elements and the compounds they form is related to their valence shells -- and learn that anything that affects the valence shell will affect the chemical and physical properties of the element!

Includes 2 programs. Program 1: Seeing Is Believing (60 min.): Today we take for granted that the earth is round, that we orbit the sun. But these things are not obvious - our knowledge today is built on the foundation of hundreds of years of study. This program explores mathematics and how it revolutionized our view of the universe. Discusses Ptolemy, Newton, Einstein, and Hubble.

Includes 2 programs. Program 1: Cosmic Alchemy (60 min.) In the beginning, the universe started as a single point. Yet from this tiny beginning came all the matter that we can see around us today. How could pure energy become matter? Over the last century, a series of discoveries have shed light on our understanding of matter.

Program Five: Black Holes and Beyond

"Biomes of the World in Action" is a fun, informative series that takes students on a fast-paced eco-adventure around the world exploring the many characteristics that make these large regions of the world different from one another.
