Monday's Lesson Plan
The last ten years of the nineteenth century were bustling with activity and insight. Scientists and inventors were devising new, more efficient techniques to complete daily tasks. Alexander Graham Bell was just one of these men. He was hired by Western Union to devise a way to send multiple telegraphs on the same line. Through his research and further experimentation he invented the telephone! People thought the telephone would be a short lived toy, but it proved to be a long lasting invention. We still use telephones everyday.

Tuesday's Lesson Plan
Until the late nineteenth century, it wasn't possible to record sound. The telegraph and telephone only transmitted sound. Thomas Edison invented a solution to this problem with his phonograph. The phonegraph captured sound waves and transferred them to cylinders that could then be played back. Edison along with William Kennedy Laurie Dickson also invented a way to record movements using the kinetoscope.

Wednesday's Lesson Plan
Perhaps one of the greatest inventions of all time was dreamt up by Thomas Edison during the late nineteenth century. After starting work on the phonograph, Edison became interested in the light bulb. Several light bulbs had already been invented, but none were pratical for commercial use. Edison invented the incadescent light bulb, the first bulb to be widely used by the public.

Thursday's Lesson Plan
The end of the ninetenth century saw the development of wireless communication. Many researchers and inventors were working with this idea of wireless telegraghy. However, it was Gugulilemo Marconi that was awarded the patent for the radio in 1896. The next year Marconi set up a radio station on the Isle of Wight, England. The radio was a means to communicate to the masses without the need for telegraph lines.

Friday's Lesson Plan
As more and more people moved to the city, the city needed more buildings. People needed places to live, work, eat, shop, and have fun. Architects decided that making a building tall instead of wide would be a good way to make lots of buildings fit into the city. These new tall buildings were called skyscrapers because they reached up into the sky.
