Technology at Work I — From the ones and zeroes of the digital revolution to the ability to predict hurricanes, tornadoes, and floods, computers have given humankind a new way to manage its environment. Whether it's the instantaneous knowledge and communication of the Internet or new robots that move just like humans, this four-segment video shows your students how computers underlie every new technological step we take.
Technology at Work 2 — The earth is a giant magnet, creating a powerful force that humans can use in many ways. Magnets store information on computer disks, convert electricity into sound in televisions, and give Global Positioning System satellites clues it needs to find the location of a transmitter anywhere on Earth. The three segments of this video show how magnetism, television, and satellites work.
