Who was the man who invented the light bulb?(Part I)

This fall we began to read a book called Who Was Thomas Alva Edison?. This book tells us about the inventions Tom makes throughout his life with a couple of funny stories. Al's family included his father Samuel, his mother Nancy, two brothers, and a sister. His first invention was an electrical voting machine. When he was growing up Al was a newsboy on the Grand Trunk Railroad, but it didn't last long because Al had a science laboratory on the train and one day he made a big explosion that got him fired. I think his early life was interesting because he made many experiments, for example the phonograph.

As Al got older everyone called him Tom, Tom's inventions got better, and his laboratories got bigger. Tom spent most of his time at work. His compound included his own house, his boarding house, and a few shop's. Tom made an electric pen that was very useful and saved time by making dots to easily copy letters, books. articles, etc.

As Tom grew older, he wanted to make a better light bulb. Tom's light bulb was better because Tom's light bulb could light up hundreds of lights at one time. Today you can see Tom's light bulbs on streets, freeways, in homes, in offices, etc. The invention of Tom's light bulb allows us to have safe light without causing fires or being smelly!

  1. Dear Samuel,

    Glad to know you are reading a new book and updating your blog. May I give you some suggestions? 1st -- you may want to update the "about me", you are no longer a 3rd grader. 2nd -- although it's nice to change color to get a new look of your blog. It seems too dark to read some of your postings..
