http://forum.brillkids.com/downloads/?sa=view;id=1226Samuel F. B. Morse
1. Samuel F.B. Morse invented the electric telegraph
2. Morse's telegraph sent messages through a wire by using a code of electric signals
3. Morse was born in Charlestown, Massachusetts, in 1791
4. As a child Morse was very interested in art, and he became a famous artist as an adult
5. Morse first demonstrated the telegraph in 1837, but could only interest one or two people in it
6. In 1844, Morse sent the first telegraph message, from Washington, D.C., to Baltimore, Maryland
7. Morse became wealthy after business people invested in the telegraph
8. Morse's telegraph transmitted sounds, not voice, and a code of long and short sounds was used to send messages
9. Amateur radio operators memorized Morse Code, his system of "dots" and "dashes" for telegraph messages
10. "SOS" is a signal that ships and planes use to call for help, which in Morse Code is
... --- ...(dot,dot,dot,dash,dash,dash,dot,dot,dot)
Eli Whitney
1. Eli Whitney invented the cotton gin
2. Whitney invented the coton gin because separating cotton from the seeds by hand took a long time
3. Whitney was born in Westborough, Massachusetts, in 1765
4. Whitney built his own vilolin when he was twelve years old, and at fourteen he began to manufacture nails
5. Whitney's first cotton gin could clean cotton as fast as fifty people doing it by hand
6. Cotton thread and cloth are made from the fibers after they are removed from the seeds of the cotton plant
7. Cotton became an improtant farm crop in the United States after the cotton gin was invented
8. Other people began to build and sell copies of Whitney's cotton gin without his permission
9. Eli Whitney invented a way to mass produce guns by making rifles that were put together from identical parts
10. Whitney did not marry until he was fifty-one, but he and his wife had four children in eight years
Benjamin Franklin
1. Benjamin Franklin proved that lightning is a form of electricity
2. Franklin's many inventions included the lightning rod, which protects buildings form damage by lightning
3. Franklin was born in Boston, Massachusetts, in 1706
4. Franklin began to work in his brother's printing shop when he was ten years old, after only two years of schooling
5. At the age of seventeen, he ran away from home to Philadelphia, where he worked as a printer

7. Ben Franklin invented a type of eyeglasses called "bifocals"
8. Besides working with electricity, Franklin made discoveries in meteorolby, geography, and agriculture
9. Franklin began post offices, fire departments, a hospital, and a university, and he helped to write the Declaration of Independence
10. His last public act was signing an appeal to the United States Congress in favor of ending slavery
Gugliemo Marconi
1. Guglielmo Marconi invented wireless telegraphy, what we now call radio
2. Wireless telegraphy sends sounds through space without using wires
3. Marconi was born in Bologna, Italy, in 1874
4. As a child, he enjoyed reading the many science books that his parents owned
5. In 1895, Marconi sent the first wireless telegraph message ove a distance of more than one mile
6. In 1901, Marconi sent a wireless telegraph message across the Atlantic Ocean
7. At first Marconi could not interest his own government in radio, so he moved to England
8. Marconi's radio sent only telegraph signals, but by 1906 other inventors were using much stronger radio signals to transmit voice and music
9. Marconi continued to improve wireless technology and used it to help the Italian government during World War I
10. The Italian government gave Marconi the title of "marquis" in 1929
