Scientists believe that Saturn, the second largest planet, would float in water if a glass were big enough. Uses computer graphics to note its features and those of its seven rings. Discusses Titan, its largest moon, and the Cassini probe, which examines it. Notes Saturn is a gas giant, has a 30-year orbit, and that astronomers create theories about this planet based on limited facts.
Firefighters risk their lives every time they run into a burning building. But, new technology may soon be watching their backs, no matter how far they venture into the flames and smoke. With support from the National Science Foundation, TRX systems is developing a new sensor system that can track firefighters where GPS units often fail.
The sun's powerful, warm rays light up the sky with brilliant color and heat. The changing cycles of the sun can affect the earth and its living organisms. The sun is similar to a living organism-just as humans are born, grow older, and die, so too will the sun. When this happens, the rest of the solar system will have no future.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the measurements of the International System of Units (SI). Part of the Science Video Vocab series.
The human body needs to take in food and water found in the environment, and through a sequence of mechanical and chemical processes, it converts that food into nutrients that sustain all the body's activities. The digestive tract alone has nine major organs devoted to this process, and the renal tract has three. Join Dr. Mark Reisman as he provides you with a look at the anatomy and physiology of the many organs and structures of digestion. Lastly, explores the properties of metabolism and nutrition.
Sirens are a small part of the sophisticated warning system used for tsunami alerts. Meteorological agencies issue warnings and send alerts to television and radio channels, the Internet, and mobile phone networks. These systems are found throughout the world and are vital for tsunami prone areas like Japan. Part of the "Danger Zone" series.
With support from the National Science Foundation, astronomers Marc Buie and John Keller are involving citizen scientists from throughout the western United States to participate in the Research and Education Cooperative Occultation Network (RECON). The project has provided telescope equipment and training to 14 small western U.S. communities north and south of Reno, Nevada, where night skies are clear and dark. When RECON students look out at the night sky, they look way out to the Kuiper Belt, a ring of icy debris that litters the Solar System out beyond Neptune. The network is looking to determine the sizes of Kuiper Belt objects as they pass in front of distant stars. Part of the National Science Foundation Series “Science Nation.”
Locked-in syndrome is a condition in which people with normal cognitive brain activity suffer severe paralysis, often from injuries or an illness such as Lou Gehrig’s disease. Boston University neuroscientist Frank Guenther conducts research on how brain regions interact, with the hope of melding mind and machine, and ultimately making life much better for people with locked-in syndrome.
The goal of this research is to determine the mechanisms underlying predatory and defensive behavior guided by an extraordinarily novel sensor in snakes. Pit vipers, pythons and boas possess special organs that form images in the brain of the thermal environment, much like vision occurs in the human brain. Thus, these snakes see heat, and this amazing system is the most sensitive infrared detector on Earth, natural or artificial. A better understanding of infrared-based thermal imaging in snakes is important not only for understanding complex behavior in these highly efficient predators, but also for understanding the evolution of imaging sensors and the behaviors they support in other animals including people. Part of the National Science Foundation Series “Science Nation.”
Students learn the process of weighing common objects. Concepts and terminology include matter, mass, weight, scale, and metric system.
Homeostasis refers to the body’s ability to maintain a stable internal environment, and maintaining homeostasis requires that the body continuously monitors its internal conditions. From body temperature to blood pressure to levels of certain nutrients, each physiological condition has a particular set point. Topics covered include homeostasis, negative feedback loop, nervous system, endocrine system, digestive system, excretory system, musculoskeletal system, and the immune system. Part of the "Biology" series.
The body's internal defense system is an extraordinarily complex and efficient mechanism. The lymphatic system is the key to the human body's immune response. Through the activation of the blood and lymphatic circulation system, many infections are successfully fought off before they gain hold in the body. Illustrates what happens when a man is infected with the common cold.
Students explore the relationship between observations and measuring things in science. Specific ways of measuring length, mass, volume, and temperature are demonstrated using tools common to the classroom. Other terminology includes unit of measurement, meter stick, metric ruler, balance, graduated cylinder, and thermometer.
Students learn the different parts of trees. They also investigate the difference between the terms deciduous and coniferous. Explore the reasons trees are important parts of the environment.
Our solar system is a fascinating place. Colorful images illustrate the major planets and their unique characteristics. Special attention is paid to what makes Earth unique in the solar system.
Cars use airbags. Packages use airbags. Why shouldn't eggs use airbags too? Students model NASA's airbag landing system in this activity from "Design Squad Nation." They design and build protective covers made of balloons to protect an egg dropped from a height of three feet. Their systems model the airbag landing systems used by three NASA Mars missions. The students use the engineering design process, apply a variety of science concepts, and learn about NASA's exploration of the solar system. Part of the "Design Squad Nation" series.
Live-action footage conveys basic features of the major invertebrate groups. Special attention is paid to the body structure and physical features of simple animals. Other terminology includes backbone, sponge, sea anemone, radial symmetry, planaria, earthworm, bilateral symmetry, exoskeleton, segmented body, and jointed appendages.
Students explore the many important uses of electricity. The nature of electricity and the formation of electric current are highlighted. Special attention is given to safety and electricity. Concepts and terminology include charge, current, lightning, battery, generator, and wiring.
Cynthia Bixby is the chief of the Systems Engineering and Integration branch at NASA Armstrong Flight Research Center. Prior to becoming chief, Bixby was the systems engineer for the Adaptive Compliant Trailing Edge project, which researched the flexiblity and efficiency of wing flaps on a NASA Gulfstream. Earlier in her NASA career, she was acting deputy and then acting chief of the Flight Systems branch. Part of the "Women@NASA" series.
While the human brain and nervous system are wired with hundreds of billions of nerve cells, or neurons, sea slugs can get by with tens of thousands. Ironically, sea slugs reveal a lot about the chemistry of the human brain and nervous system. In fact, they are ideal as study subjects for research on learning, memory, and how neurons control behavior. With support from the National Science Foundation, analytical chemist Jonathan Sweedler and his team at the University of Illinois are working to develop new measurement tools that enable insights into the function of individual cells in the central nervous systems of slugs and other animals in order to uncover novel neurochemical pathways. Part of the National Science Foundation Series “Science Nation.”
