With current extinction rates exceeding those of previous mass extinctions, many biodiversity studies focus on efforts to count the Earth
Change is Gonna Come - Karla is having a lot of fun with her new tadpole friend, until one day, when she finds that he's changed completely. Why did he have to go and do that. Mama explains (with some help from her home movies) how change is something that happens to everyone in the animal kingdom -- it just happens faster to some than others. Trumpet While You Work - Max wants Mama to play, but she has to work, as does the local "tale-spinning" orb spider. As a result, Max wants to know why adults always have to "work."

The conventional notion of dimension consists of three degrees of freedom: length, width, and height, each of which is a quantity that can be measured independently of the others. Many mathematical objects, however, require more
From the tower of the Old North Church where Robert Newman gave the signal that the British were coming, Dave recalls the beginnings of the American Revolution. He explains that Boston Puritans felt they had a God-given right to revolt against tyrants who taxed them without representation. At the Hancock Clark House in Lexington, Dave reviews the biographies of John Hancock and the Reverend Jones Clark, and the reasons why the British accused them of treason. On Lexington Green, Dave reviews the history of the "shot heard 'round the world", and at Old North Bridge, Concorde, the American success and the subsequent British retreat. Next, at Bunker Hill, Dave provides a detailed account of the heavy fighting and numerous causalities in a conflict where the Americans established themselves as a solid fighting force. He closes with the story of Henry Knox who, with the approval of George Washington, brought British cannons 300 miles from Fort Ticonderoga to Dorchester Heights in Boston.
Connections can be physical, as with bridges, or immaterial, as with friendships. Both types of connections can be understood using the same mathematical framework called network theory, or graph theory, which is a way to abstract and quantify the notion of connectivity. This unit looks at how this branch of mathematics provides insights into extremely complicated networks such as ecosystems.
Teachers step outside of the classroom - and into their students' home to get to know families better. We visit programs in Sacramento and Los Angeles to see how this "home visit" model is working. Plus, we look at school funding through the eyes of two districts: Oakland and Merced. And an effort to teach kids about the dairy industry by bringing cows directly to their school in Rancho Cordova.
In Good Shape is the weekly health show on DW, covering all aspects of health care: what's new in medical treatment, alternative medicine, wellness and fitness - as well as nutrition and beauty. In our studio interview we discuss topics in-depth with specialists, and offer you opportunities to pose your own questions. Dr. Carsten Lekutat and Stefanie Suren are alternate hosts of the program and will provide a combination of video-rich features and insightful interviews that grapple with some of the larger issues in medical treatment and healthcare. As an interactive feature of the program we also ask viewers to request a program topic Dr. Carsten Lekutat is a qualified General Practitioner and works as a doctor in Berlin. He is also responsible for training medical students at the Berlin Charite hospital. Stefanie Suren is executive producer and presenter of In Good Shape. 'Keep it simple and straightforward' - that is her goal as a reporter, producer and presenter.
What tools do world historians use in the study of history? This unit begins the study of world history by examining its use of geographical and chronological frameworks: how they have shaped the understanding of world history and have been used to chart the past.
A new urban middle class emerged, while dynastic marriages established centralized monarchies.
Earth and space science is covered. Guests explain concepts of geology, meteorology, astronomy, biology, and earth science. Among the topics are: the formation of life on earth, earthquakes and plate tectonics, the rock cycle, the water cycle, pollution, weather patterns and climate, and renewable and non-renewable energy sources. The Rock Cycle looks at what has happened on earth and what likely will happen. The form that rocks take reflects a point in time and can be transformed from earth's interior to mantle to magma to igneous rock to sediment to sedimentary rock to metamorphic rock. Also: seismologists' ability to predict where, but not when, earthquakes will occur; and a diagram of the water cycle to demonstrate the importance of knowing how to read graphics on the GED exam.
