students explore how wireless communications and other mobile technologies have changed the ways and places people work. They design 'mobile learning labs' to demonstrate how these technologies might impact their current workplace and...

Students explain how power is transmitted over long distances. In this physics lesson, students simulate controlling power flow in parallel transmission lines. They discuss several applications of wireless power transmission.

Ninth graders create a model of greenhouse effect in the lab. In this integrated science lesson, 9th graders investigate the different variables affecting this condition. They research about global warming and prepare a PowerPoint...

Students participate in hands-on, computer activities to demonstrate the addition and subtraction of mathematical situations. Given a story problem, students determine when to add or subtract. Using word processing technology, students...

Students brainstorm a list of potential uses for micro-video technologies. After reading an article, they analyze the development of a new pill-sized camera. In groups, they create a children's book that shows them the various systems of...

Students investigate the Underground Railroad. In this slavery lesson plan, students read books about slavery, the Undeground Railroad, and how slaves escaped the south. Students develop knowledge about coded songs and constellations...

Middle schoolers complete a table of values and plot points, as well as construct a graph on a coordinate grid. They construct two graphs on the same coordinate system, and identify the point of intersection. Students represent and...

Students design a quilt square to reflect their special memory. In this family heirlooms lesson, students read The Patchwork Quilt and discuss the importance of family involvement in creating a family heirloom. Students write and publish...

A number of distinguished scientists had a hand in the discovery of "wireless telegraphy," but it was the work done by Guglielmo Marconi that is credited with providing the basis of radio as we know it today.

Awarded more than 100 patents over the course of his lifetime, Nikola Tesla was a man of considerable genius and vision. He was reportedly born at exactly midnight during an electrical storm, an intriguing beginning for a man who would...

Sir Oliver Lodge's experiment demonstrating the first tunable radio receiver was an important stepping stone on the path toward the invention of a practical radio.

Scientists discover and probe x-rays and radioactivity, while inventors compete to build the first radio.
