Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term simple machine. Part of the Science Video Vocab Series.
Stephen Fry, writer and actor, gathers a team of craftsmen to help him build a copy of Gutenberg's printing press and sets himself the task of learning how to make the paper and type to print as Gutenberg once did. These practical trials and tests demonstrate the brilliance of Gutenberg's invention and bring the man and his machine to life. Also investigates why printing mattered so much to Gutenberg and his contemporaries, exploring the political and religious turmoil that shaped Gutenberg's world.
What is the science behind a teeter-totter or slide? Students learn about simple machines as they explore the playground. Part of the “Everyday Science for Preschoolers” series.
With support from the National Science Foundation, chemist Kent Kirshenbaum and his team at New York University are engineering molecules to mimic the shapes, structures, and functions of natural proteins. The ultimate goal of this biomimetic chemistry research is to develop a reliable way to build synthetic proteins that can be put to work at the industrial scale. Part of the "Science Nation" series.
Everyday people do work, and most of the time they use tools to help them. First, students gain an understanding of work. Next they explore the relationship between work and energy. Common examples of tools used to make work easier are highlighted. Concepts and terminology discussed include: work, energy, machine, simple machine, wedge, wheel and axle, and lever.
A string of gumballs all the same color mysteriously fall out of a gumball machine. Yana and Egbert set out to explore this phenomena. This episode explores the relationship between samples, populations, random sampling, and selective sampling. Part of the "Yana & Egbert" series.
The scientists explore the absorbency of rice. They will also create a pendulum wave machine and make the perfect paper plane. Part of the House of Science Series.
A small prairie town has few secrets but in Balgonie, Saskatchewan, William (Bill) Wallace Gibson had one. Each night, when most folks were home asleep, Bill was busy in his workshop. Bill had a dream. He was building a flying machine. This short puppet animation tells his story.
Professor Kaos has invented a machine that allows cows to produce chocolate milk. After seeing the chocolate milk-producing cows, Olli senses something is wrong. The children are left to wonder if the invention causes more problems than it solves? They help Professor Kaos realize that his invention is hurting the cows. Part of the "My Little Planet" series.
This award-winning documentary on LIGO, NSF's Laser Interferometer Gravitational Wave Observatory, examines how LIGO is spearheading the new field of gravitational wave astronomy and opening a whole new window on the universe. LIGO's exquisitely sensitive instruments may ultimately take scientists farther back in time than ever before, catching, perhaps, the first murmurs of the universe in formation.
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. There's something dazzling in Ms. Frizzle's closet: a magical, light-powered pinball machine. To win at this game, the kids have to light up all six colors of the rainbow. Now the race is on, as the class shrinks down and zooms into the pinball machine. They will have to learn how to reflect all of the light to combine it into one beam to make their escape.
The researchers are building scaffolds that mimic the three dimensional structure of human tissue. They use a machine called a biofabricator to deposit cancer cells at strategic locations inside the 3D structures, just like tumors in human flesh. These structures are high fidelity test systems. Burg and her team can culture cancer cells in them, experimenting to see which treatments are the most effective, with the ultimate goal of personalizing a treatment or a vaccine for individual patients. Part of the National Science Foundation Series “Science Nation.”
Go behind the scenes with Angelina and investigate the equipment and engineering skills needed to recreate ocean habitats. Explore a typical workspace of an aquarium and get a feel for the everyday problem solving skills needed as an aquarist. Part of the "Aquarist" series.
Part of the "Active Physical Science" series. Provides an overview of the basic concepts of physical and chemical science. Contains the following sections: (1) "Air Quality," which contains "Test of Two Gasses Using a Glowing Splint," "Combustion in a Car Engine," "Convection," and "Inversion"; (2) "Energy," which contains, "Student Rube Goldberg Machines" and "What Affects a Cart's Kinetic Energy?"; and "How Do Machines Help Build Big Things?"
Bullfrogs have arrived in the Arizona Desert, and conservationists are hopping mad. The alien species is wrecking havoc on native frog species. Segment of video from Wild Chronicles Series.
Video art has become one of the most fashionable artistic disciplines since its inception in the 60s. Festivals like "Loop " and exhibitions at MACBA like The Killing Machine have recently demonstrated the creative possibilities in this creative medium. Video art closely links the continuous changes that occur in electronic and digital technology.
What is frequency? Why is it so important for radio and sound waves? Adabot gets all the answers from Ladyada and a new friend. Part of the "Circuit Playground" series.
Meet three mechanical engineers who are designing the next generation of jet engines at a major U.S. company. They explain how their curiosity about how things work led them to advanced engineering degrees and cool careers with aircraft engines. Part of the "Career Connections" series.
