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 correct methods to clean up and dispose of materials in a science lab. Students also learn how to safely clean up chemical spills. Part of the Science Video Vocab series.

Imagine if there were electronics able to prevent epileptic seizures before they happen, or electronics that could be placed on the surface of a beating heart to monitor its functions. The problem is that such devices are a tough fit. Body tissue is soft and pliable while conventional circuits can be hard and brittle--at least until now. Materials scientist John Rogers at the University of Illinois Urbana-Champaign is working to develop elastic electronics.
Access to safe drinking water is a global problem for nearly a billion people. For approximately 200 million people, many in Africa, high levels of naturally occurring fluoride in the water cause disfiguring and debilitating dental and skeletal disease. University of Oklahoma environmental scientist Laura Brunson is back from Ethiopia where, with support from the National Science Foundation, she’s developing fluoride filtering devices that use inexpensive materials readily available right there in the villages.
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.

The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Two inches tall and trapped in a bathroom at Wanda's house, the kids have to get out before Wanda's mother discovers them. The kids use what they've learned about structures to construct a series of towers and bridges across the bathroom to an open window.
As a boy growing up in Brazil 40 years ago, Marc Meyers marveled at the lightweight toughness of toucan beaks that he occasionally found on the forest floor. Now, with support from the National Science Foundation, the materials scientist and mechanical and aerospace engineer at UC San Diego, is conducting the first ever detailed engineering analysis of toucan beaks. He says makers of airplanes and automobiles may benefit from his findings. In fact, panels that mimic toucan beaks may offer better protection to motorists involved in crashes.
At the National Science Foundation-funded Center for Environmental Implications of Nanotechnology (CEINT), headquartered at Duke University, scientists and engineers are researching how nanoscale materials affect living things. One of CEINT's main goals is to develop tools that can help assess possible risks to human health and the environment. A key aspect of this research happens in mesocosms, which are outdoor experiments that simulate the natural environment. These simulated wetlands in Duke Forest serve as a test bed for exploring how nanomaterials move through an ecosystem and impact living things. Part of the “Science Nation” series.
With support from the National Science Foundation, aerospace engineer Michael Philen and his team at Virginia Tech are investigating the biomechanics of fish locomotion, in hopes of contributing to the next generation of robotic fish and underwater submersibles. They’re studying how fish use their muscles to swim efficiently and execute underwater maneuvers, such as darting around in perfectly synchronized schools. They’re also developing new smart materials, such as a bioengineered hair that is modeled after the hair cell sensors on the side of fish that allow it to detect minute changes in water flow.

Engineers and architects are creating bridges that combine the best of both art and design. Bridges are no longer just a tool to get from one side of the river to the other. Some bridges have the goal of being aesthetically pleasing and efficient for pedestrians. Others rely on the cantilever design to span a distance equivalent to three and a half jumbo jets. Bridges are often classified by their structure and how the forces of tension, compression, bending, torsion and shear are distributed. Shows how designs vary depending on the function of the bridge, the environmental factors, the materials, and technology used to construct them.
One day, microbes will eliminate dirt and garbage, filter exhaust systems, and help make self-cleaning clothing possible. Takes viewers on a global journey-from the U.S. to Iceland, Sweden, India, China, Senegal, and Australia-to meet the world's leading specialists in bacteriology and to discover the incredible abilities of the microscopic life-forms they study. Employs state-of-the-art imaging technology and animation to illustrate how bacteria have learned to adapt to harsh environments and how they can be found in a vast array of human-made products and materials, including medicines, pesticides, plastics, solvents, and even electroacoustic speakers.
Part of the "Life in Aquatic Environments" series. Places many of the organisms into an ecological perspective of hydras, planarians, annelids, aquatic insects, rotifers, protists, and all other organisms that provide food for fish and other vertebrates. Observes adaptations for planktonic life in daphnia and other cladocerans, copepods, rotifers, and planktonic algae. Explores bacterial decomposition, recycling of materials, adaptations for bottom life, and ecological relationships in the bottom community. Takes an underwater look at the highly specialized organisms that live in rapids, under rock communities, and in slower waters. Investigates adaptations for life in temporary wetland environments.
Explores the need for many multicellular plants to have specialized internal transport systems, which are systems that can efficiently distribute materials from soil and leaves to the parts of the plants where they are needed. An overview of how plants obtain their nutrients is provided. The structure and function of root hairs is explored, explaining their remarkable ability to facilitate an enormous uptake of water and dissolved minerals for the plant. Following this, the separate transport systems of the xylem and phloem are explored in detail. Also explains the mechanisms by which vascular plants transport water and minerals upward from the roots as well as sugars from leaves and other sugar sources throughout the plant for storage or for growth and repair.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. It's the last day of school before the winter holidays, and Wanda plans to see the Nutcracker ballet. But during a trip to a recycling plant, her toy soldier accidentally gets recycled. Devastated, Wanda wishes for a world without recycling. Ms. Frizzle activates the bus's un-recycler, taking the class on a song-filled field trip.
A Category 5 hurricane is a monster of a storm that most people would want to avoid. But, Civil Engineer Arindam Chowdhury actually recreates those monster hurricane force winds in hopes of helping people better prepare for the real thing. With support from the National Science Foundation, Chowdhury and his team at Florida International University and the International Hurricane Research Center designed a 15 foot tall Wall of Wind (WOW). The goal is to see if low rise structures and building materials can withstand the same wind forces they would face in a full-blown hurricane.
