Has technology made household chores easier to perform? A team of experimenters head into the kitchen to answer the question. They realize the choice of materials and the application of ergonomic principles in the design of appliances has helped increase the efficiency of daily routines. Part of Invisible Science and Technology Surrounding Series.
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 safety procedures for handling dangerous materials in a lab. Part of the Science Video Vocab series.
Have you ever wondered what happens to a home after it is demolished? Join Joel and the Curiosity Quest crew to find out how 95% of a home can be recycled, including the interior. Part of the Curiosity Quest Series.
What is a botanist? The researchers in the A to Z Career Lab investigate the roles and responsibilities of botanists, and they report their findings to inquisitive students. Part of the "I Can Be Anything I Want to Be A to Z" series.
The Standard Deviants explore volcanoes and what causes them to erupt. They also discuss lava, pyroclastic materials, and the Ring of Fire. Then, it's time for a discussion on weathering. Part of "The Rockin' World of Geology" series.
Josh Landis and Mitch Butler discuss metamaterials, a type of nanotechnology. These materials can theoretically make objects disappear from plain sight. This cloaking technology has a wide range of applications and could forever change the view of the world. Part of the Fast Draw Series.
If everyone would just put more in the recycling bin instead of the trash can, the world would be a better place. Right? In this episode, host Joe Hanson discusses the current state of recycling and offers ways to enhance the current methods of recycling. Part of the "It's Okay to Be Smart" series.
What happens to the stuff flushed down a drain? How do velocity and friction factor into this system? Get down and dirty to see how the sewer system relies on these elements of force. The experts develop tracking gadgets that journey through the sewer system hot on the trail of the flushed materials. Part of the "Break It Down" series.
NOVA follows three reporters from "The New York Times" as they travel the world researching biological weapons for their book, "Germs: Biological Weapons and America's Secret War," and for this documentary. Addresses the questions: Where do germ weapons come from? Who has access to them? Can the air we breathe become a weapon? Can America defend itself against germ warfare?
This video introduces science lab safety guidelines. Some topics covered include discussions on proper lab attire, importance of proper disposal of materials, and precautions when heating substances. Part of "The Amoeba Sisters" series.
Part of the "Green Careers" series. Introduces job opportunities in recycling, including collection, transportation, receiving and sorting, disassembly, handling hazardous materials, scheduling, operations, and plant management. Recycling provides opportunities for young people to start with a temporary or part-time job, then move up to supervisory and management responsibilities. Jobs profiled include the following: e-waste entrepreneur, plant manager, biofuel coordinator, and truck driver.
A key to building denser, stronger materials that won’t fail or fracture under extreme conditions is the manufacture of ultra-high temperature, or UHT, ceramics. UHT ceramics can withstand highly extreme conditions, such as the heat coming out of a rocket as its launching into space. Part of the National Science Foundation Series “Science Nation.”
Magnets can be found in many objects used everyday. Not only are they located in man-made objects, but magnetic materials can be found in nature as well. Students will gain general information about magnetism, as well as concepts about atoms and the relationship between electricity and magnets. Part of the Real World Science series.
Some things die and decay and others don't. A walk in the park teaches that leaves, logs, and animals are examples of things that decay or rot. An elementary class buries apple, potato, and banana skins, bread, a plastic tray, and an aluminum can. They learn what decays and what will not. Some things that don't decay can be recycled; those that do, enrich the earth.
Second in the series of three productions designed to let students learn by doing, guiding them through the science and history behind the Wright Brothers' invention of powered flight. This second component contains segments that provide science background (Four Forces of Flight, Newton's Laws, and others) to help students understand aviation concepts. Additional segments show the teacher how to conduct activities (building models or demonstrations) and acquire materials to be used in these activities.
With support from the National Science Foundation, some Brown University scientists are doing extensive research on bats, studying everything from their agility in flight to the elasticity of their bodies. Researching a bat's evolution, its structure and biomechanics in flight will help scientists better understand evolution and could lead to the development of aerodynamic materials for more lightweight, agile aircraft.
The National Science Foundation's National High Magnetic Field Laboratory, or National MagLab, is a global destination for ground-breaking research across scientific disciplines. Nearly 2,000 scientists from around the world use the MagLab's facilities each year to study the power of high magnetic fields. They explore new physical phenomena and develop materials for future technologies. Part of the "Science Nation" series.
This episode features the development of a new camera that detects cancer. Its design is based on the structure of a butterfly's eye. Scientists are also experimenting with ominphobic materials that repel dirt. Studies also reveal that animals are beginning to recolonize ecosystems that were once prime hunting grounds for them. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Researchers explore how different types of biomass can be used to produce fuel. One researcher is building reactors to grow algae used to create biofuel. A different study examines how leafcutter ants break down biomass in order to convert cellulose in plants to a fermentable sugar used to make ethanol. Finally, an engineer uses chemistry and heat to turn sawmill waste into bio-oil and gasoline.
