With support from the National Science Foundation, Center Director Doug Keszler and his team in the College of Science at Oregon State University are developing the next generation of electronic circuits, starting with the basic computer chip. In the manufacturing process, they want to replace bulky carbon compounds with metal oxides, in order to put more transistors onto a chip. The new process would be cleaner, faster and cheaper. Part of the National Science Foundation Series “Science Nation.”
Parasitoid insects are veritable serial killers, and they play a major role in the regulation of insect populations. Scientific research on the lines of a criminal investigation reveals how these killers behave and what remarkable capabilities they have. In basic research, parasitoids make excellent models for behavioral ecology studies. They are also used in applied research, notably for biological control, where they can serve as precious auxiliaries for controlling crop pests. Parasitoids still have many secrets to reveal, and new research avenues are opening up.
Offers an overview of the basics of scientific classification of all living organisms by arranging and categorizing them into seven main groups: Kingdom, Phylum, Class, Order, Family, Genus, and Species. Gives and explains examples of each group within the animal and plant kingdoms. A science quiz is given after each grouping.
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.
Access to affordable, sustainable energy supplies is a growing concern around the world. Looks at successful enterprises that are providing some renewable energy solutions. In Scotland, small-scale turbines put wind power within the reach of domestic users. In Sweden, the world's first train to be run solely on biogas has been developed. In Nepal, biogas stoves are improving the quality of life in many ways. And in India, agricultural-plant waste is being turned into solid fuel briquettes for use in industrial stoves and boilers, while a solar-energy company has developed environmentally friendly lighting technology that disadvantaged communities can afford.
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.
Part of the "A 3-D Demonstration" series. Explores the basic principles behind the operation of AC and DC motors. Explains how one or more fixed magnets, either permanent or electromagnetic, can cause linear movement or rotation of a current-carrying wire. A hand rule is developed to predict motor force. Motor torque is explained as a prelude to the practical design of a direct current motor. Specific modules include Motors and Magnets, Current and Magnet Interaction, Left-Hand Rule, Motor Force, Motor Torque, and DC Motors. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Qualcomm Thinkabit Lab engineer Saura Naderi teaches students how to make an LED light up and blink. Naderi demonstrates the basics of programming an Arduino board, as well as introduces coding and engineering vocabulary.
Host Peter Tonge visits the Weston Maple Sugar Project in Weston, Massachusetts. Shows the process of making maple syrup from tapping a maple sugar tree to boiling sap in a sugar shack. The second part of the program focuses on the basics of planning a garden in late winter. Also explains how to mix and apply liquid fertilizers. Originally aired as an episode of "The Good Green Earth."
Cubelets are magnetic, electronic building blocks, each with a small computer inside, that can be connected in many different ways to move around a table, follow a hand signal, turn on a light, play sounds, or do many other creative tasks. They were developed by Eric Schweikardt and his team at Modular Robotics, with support from the National Science Foundation’s Small Business Innovation Research (SBIR) program. These 21st century building blocks are meant to help kids learn about the basics of robotics while boosting their confidence to solve problems.
Hurricanes are one of the most powerful and destructive forces on Earth. How do they form? The formation of a hurricane is complicated, but basically, it depends on 3 factors: warm water, moist air, and converging winds. Part of the "Danger Zone" series.
What’s on the menu? Find out how aquarists feed some of the largest and smallest aquarium animals under their care. Understanding marine food webs, animal behavior, and nutrition are important skills needed for this science-based career. Part of the "Aquarist" series.
Like everyone else, George Huber knows money doesn't grow on trees. But, ask him where gasoline comes from and he won't just tell you, he'll show you. To fully understand, Science Nation recently went with Huber to a local lumber yard in Amherst, Mass. A lumber yard is the perfect place to find cellulose, the key building block in plant cells and the organic material that gives plants their structure. So what does cellulose have to do with gasoline? A lot.
