Scientists from the Smithsonian Center for Tropical Research document the astounding abundance of diversity in tropical rainforests to discover why so many species coexist that are competing for the same resources. In North America, the Yellowstone Wolf Reintroduction project explores why removing just one species dramatically changed the distribution of plants and animals up and down the food web.
Savanna Lullaby - Our three kids are having trouble going to bed, and Mama shows them that the most important thing about bedtime is having a routine (and a good lullaby, of course). It Gives You Paws - A game of follow the leader nearly goes awry when our friends find that they're unable to follow each other on certain terrain, leading Mama to show a movie or two about the very specialized hands and feet of different animals.
Observing molecules during chemical reactions helps explain the role of catalysts. Dynamicnequilibrium is also demonstrated.n
Competition and cooperation can be studied mathematically, an idea that first arose in the analysis of games like chess and checkers, but soon showed its relevance to economics and geopolitical strategy. This unit shows how conflict and strategies can be thought about mathematically, and how doing so can reveal important insights about human and even animal behaviors.
Throughout the ages, the notion of infinity has been a source of mystery and paradox, a philosophical question to ponder. As a mathematical concept, infinity is at the heart of calculus, the notion of irrational numbers
Refugee students in San Diego experience the challenges and rewards of an American education.
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.

This program on physics is the last of five programs in the science section of the GED Connection series, which helps prepare students for the GED exam. Physics is the study of forces that move things. Matter is anything that takes up space or has a mass. The program features guests of various disciplines who explain specific applications of physics concepts. The first segment uses the physics of roller coasters to explain the three laws of motion. Energy is defined as the ability to do work; work involves moving something by using a force at a distance. Potential and kinetic energy are discussed. There are three "Test Connection" segments where the host underscores previous lessons dealing with the three laws of motion, the relationship between space flight and the laws of thermodynamics involving heat; and how to apply information about sound waves in helping students to read charts on the GED exam and beyond. A segment called "The Science of Sound" presents a physics teacher who also sings about such physics themes as the mechanics of sound waves. Also covered are distinctions between electricity and magnetism, as well as current and voltage. The electromagnetic spectrum consists of waves traveling at the speed of light, including visible light. Another feature is the use of electromagnetic waves by MRI technician.
