Where does the water from sinks and showers come from? Join host Joel Greene as he explores how many cities capture and treat rain water and snow melt. The treated water is then pumped into homes. Part of the Curiosity Quest Series.

Follow a chemical engineer at an oil refinery as he interacts with team members and uses technology to keep the refinery working at optimum levels. He also offers advice on educational and co-op opportunities for becoming a chemical engineer. Part of the "Career Connections" series.
Clearly shows the environmental impacts of both renewable and nonrenewable energy sources. Provides an overview of numerous renewable energy sources, how the energy is collected, and the pros and cons of renewable energy. Also explores what is happening around the globe with the introduction of wind farms, wave parks, and solar farms.
Natural selection is a process which affects every species on Earth, including humans. Illustrates how it continues to affect humans all in fundamental ways that will determine the future survival as the species. Includes a brief explanation of natural selection, examples of how it is operating all around humans, how it has affected human evolution, and how it is still affecting daily lives. Concludes with the reciprocal view of how modern human society is affecting the processes in the environment, and the consequences for the future of life on Earth.
Explains the science behind the workings of a nuclear power station. The basic version explores what fission is; the role of cooling water in nuclear reactors; the nuclear fuel cycle on mining, milling, enrichment, fabrication, and spent fuel on storage and reprocessing; and other uses of nuclear energy, including "non-power" uses. The advanced version expands on this information with a specific example of a fission reaction; the use of water to vary reactor power; different methods of mining uranium; a detailed discussion of enrichment, including structure and properties of uranium hexafluoride; and two methods of enrichment: centrifuging and gas diffusion.
Defining color is a complex process that has consumed artists and scientists for many years. Takes a new approach to the understanding of color, providing a comprehensive overview of what it is, along with very clear, detailed explanations. Three-dimensional graphics help enable full understanding of all the dimensions of color and how it relates to creative visual arts.
Genetic modification of organisms and cloning is controversial. Looks at the way humanity has modified genomes of plants and animals used for food since the dawn of agriculture. As knowledge of cells and genetics has increased, so has humanity's ability to alter genomes. Shows animations of how genetic engineers are now able to construct and insert genes for desirable characteristics into plants and how technology is used to increase numbers of animals with desirable traits and screen out those with disease or lower food yields.
Climate is what you expect, and weather is what you get. Climate is about long-term records, trends, and averages; weather is about day-to-day experiences. Introduces us to the basics and science of meteorology from its earliest theoretical and observational development to the invention of equipment (the thermometer, barometer, and hygrometer) that led to meteorology becoming a science.
Cosmetics are big business. They are used by almost every person walking on the Earth. Shows how cosmetics are made and how they have been used for thousands of years. Outlines bases, bulking agents, coloring agents, fragrances, and preservatives. Demonstrates the making of an emulsion and explains the processes of distillation or solvent extraction.
Rocks, a naturally formed material that covers the earth, are classified by their origin. Discusses rocks' composition, three types (igneous, sedimentary, and metamorphic), how they are formed, and how they are changed. The rock cycle is a slow, ongoing process.
Most of the world's insects undergo one of two types of metamorphosis: complete and incomplete. Uses the praying mantis to show an incomplete metamorphosis and the Monarch butterfly as an example of a complete metamorphosis. Includes general characteristics of insects, and gives several examples of both types of changes.
Establishes the vital importance of the greenhouse effect for life on Earth. Presents a balanced argument to assess whether anthropogenic climate change-often called "global warming"-is in fact taking place. Offers clear arguments on both sides of the debate and illustrates both more economically developed countries and less economically developed countries. Provides a thorough and balanced examination of this important and often contentious issue.
Fieldwork is a critical part of geography, and involves a range of techniques. Two young commandos are on a fieldwork mission to research and report on the human impact in two geographical regions: one urban and one within a national park. Along the way they learn about preparation, collecting primary and secondary data, equipment, note taking, photographic recording, surveying and interviewing, and presenting findings. They also talk to park rangers who work in both areas and ultimately come to understand the importance of accurate, well-prepared fieldwork.
Investigates the major body systems that are important during physical activity: the skeletal, muscular, cardiovascular, respiratory, and nervous systems. Examines each of these systems, their parts, their functions, and how they work. Also, explores the contribution and interaction of the systems when we exercise and while we are rest.
Examines the impact of emerging technologies on the innovation process by showing a range of examples. Explores the meaning of innovation and emerging technology, the innovation cycle, and what makes an innovation successful. A case study of an innovation demonstrates the innovation process. Ends with a discussion of the impacts of innovation on society, including a strong emphasis on ethical and environmental issues.
A mutagen is any agent (physical, chemical, or biological) capable of altering the structure of DNA within human cells. This program explores how some mutations are a natural process resulting from errors in the copying and repair of DNA and how some mutagens naturally exist in the world (e.g., UV radiation, cosmic rays, and some radioactive isotopes). Others are specific chemicals that have been synthesized for use in manufacturing or other industries. Mutagens may also arise during the metabolism of certain foods. In many cases mutagens may also lead to the development of cancers.
The transfer of heat is one of the fundamentals of scientific inquiry. Using numerous examples of how heat transfer is used in everyday life, this program takes students on a journey through the mechanisms and practicalities of heat transfer, clearly explaining the mechanisms of conduction, convection, and radiation and introducing the concept of thermal capacity of an object.
Provides an overview of how Newton's three laws of motion can be used to explain and predict the motion of everyday objects. The effect of friction, including air resistance, is highlighted, and the concept of inertia is illustrated with classic demonstrations. Features questions for class discussion, as well as the remarkable Rocketman, who provides a dramatic example of the third law in action.
Covers the concept of ratios and proportions, the correct way to express and write ratios and proportions, ratios and proportions in their simplest form, and comparing ratios and proportions. Provides real-life situations in which ratios and proportions would be applied, such as mixing paint, reading and interpreting map scales, and calculating map distances.
Microorganisms affect everyone. Some are helpful, while others are harmful. Explores pathogenic microorganisms that can cause diseases like sore throats, influenza, tuberculosis, and HIV; decomposer microorganisms that decay rotting plant and animal matter, returning important nutrients back into the soil; and microorganisms that are also being used in the fuel industry to develop new nonpetroleum based products. Overviews food spoilage microorganisms such as mold that can ruin stored food. Explains other bacteria and yeasts are vital to the production of food and drinks like yogurt and bread, along with beer and wine. Examines where they come from and some examples of positive uses relating to many foods we eat.
