Over the course of its 4.5 billion-year history, Earth has undergone a great number of changes -- from a red-hot ball of molten lava to a planet with an environment capable of sustaining life. In All About Earth's History, children will trace the evolution of Earth and the organisms that populate it. Young viewers will take a peek deep inside the Earth, examining its varied layers while discussing how scientists use fossils to help map out the complex time line of events that has changed Earth over millions of years.
The great civilizations of Latin America were devastated after the arrival of the conquistadors and later the European colonizers, who created a society that was characterized by extreme differences between rich and poor - a legacy that continues to plague Latin America to a strong degree today. Although Latin American nations are no longer ruled by military dictatorships and have embraced democracy, social problems associated with the large income gap, such as poverty, landlessness and crime are pervasive.
Genocide, the systematic destruction of a group of people, associated most readily with the Holocaust, tragically remains a major global issue today. Despite the lessons learned from planned exterminations such as the Armenian Massacre, the international response was limited in subsequent genocides in countries like Cambodia and Rwanda. This show defines genocide, explores the nature and causes of the crime, and shows students how the world community attempts to monitor global conditions and prevent future atrocities.

Walking on a balance beam or riding a bike both require motion and balance. This program will reveal how unbalanced forces create motion, while balanced forces keep things still. Students also learn how concepts like velocity, acceleration and momentum fit into this puzzle. A unique hands-on activity combined with vivid imagery and graphics will clearly illustrate these concepts to students.
