Telephone NotesTelephone was invented by Alexander Graham Bell in 1876 in Cambridge, Massachusetts. Bell’s first call was to Thomas Watson (who was in another room in the same building).His first telephone message was “Mr. Watson, come here. I want you.”   The famous duo of Alexander Graham Bell and Thomas A. Watson made history again when the first transcontinental telephone call occurred on January 25, 1915. Watson was in San Francisco, California, when Bell called him from New York, New York. President Woodrow Wilson and the mayors of both cities were also part of the call. Bell also investigated causes of deafness.

Goddard and an Early Rocket

Robert Goddard fired the first liquid-fueled rocket in 1926 in Cambridge, Massachusetts. Prior to this launch, only solid-fueled propellents had been constructed. His work regarding different fuels and rockets became the foundation of America’s space program. Older children can see how liquid-fueled rockets work at: http://science.howstuffworks.com/rocket5.htm.
