See how the political, religious and social events of 16th-century Europe changed the course of history. Examine the context in which these factors sparked the birth of Protestant Christianity. Led by Martin Luther, this spiritual revolution gained momentum and, under the helm of other Protestant leaders, thrived and grew into new factions in Europe and North America.

From the public ministry of Jesus to the legendary battles of the Crusades, examine the interwoven histories of these two distinct branches of Christianity. Although its followers were long persecuted by the Roman Empire, Christianity spread throughout the Mediterranean region and eventually became the favored religion of the Empire, following the ascension of Constantine to the Roman throne.

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!

"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.

From the arctic tundra found in the Polar zones to the regions of alpine tundra located on the mountaintops of Europe and North America, students will get an up-close look at this fragile biome. Students explore the biodiversity that exists in these frozen expanses, while a fun, hands-on experiment demonstrates why so many tundra plants are dark in color.
