First of all, sorry this is late.

Second of all, in my book, Girls Think of Everything by Catherine Thimmesh, it's about how different girls make different creations to make life a bit easier. I found this book in my science classroom and thought that it would be interesting.

One example of a girl that invented something is Ruth Wakefield. I think kids and even adults should thank her. Do you know why? You should thank her for inventing the chocolate chip cookie. Ruth and her husband took the old Toll House, which was a stop for horses, and turned it into an inn. The Toll House Inn that served people, not horses. And as the co-owner, manger, hostess, and cook, Ruth was very busy. One day (apparently in 1930) she was in a hurry and still had to make chocolate-butter cookies, which were famous then. She had to melt chocolate squares and pour it into the batter. Instead, she just cut the chocolate squares into pieces and thought that when she put it in the oven, the chocolate would melt and turn in chocolate-butter cookies. But she was wrong. She was staring at what she called ruined chocolate-butter cookies, but what she didn't know was that they would be delicious. Really delicious. Then she tasted them. And so did her customers. As I like to call it, it would have been like heaven. (I mean, don't you feel good when you eat a nice fresh chocolate chip cookie?) And that was how the chocolate chip cookie was invented.

Another example of an invention invented by a girl (or women) is the windshield wipers. Even though it isn't as delicious as chocolate chip cookies, it was smart and clever. It started as a dreadful, terrible day; because of the weather. It was snowy and there was sleet and people were buried in their blankets. Mary Anderson of Birmingham, Alabama, went inside a New York City streetcar. It was the year 1902. See, she feel sorry for the driver because it was difficult for him to see the road (or, in this case, street). Before, engineers split the windshield, and when the glass was covered with snow, the driver would open the middle for a clearer view. Unfortunately for him, the snow and sleet just ended up coming through the split and onto the driver. Mary Anderson thought to herself, what if there was something out of the window that which push the snow off of the window? And there would just be a lever to push to move it around the window? When she shared her idea, people said that it couldn't be done, but Mary didn't believe them. In Birmingham, she drew sketches, examining them, making them more elaborate. And after testing and experimenting, Mary finally created and was awarded with a patent, for creating the first window-cleaning device. And that's how the windshield wipers were invented.

The third example of an invention is Glo-Sheet. Invented by Becky Schroeder. It all started when Becky as waiting for her mom to finish shopping and she was in the car. She decided to finish her math homework. But it was getting dark and Becky couldn't see her paper. She didn't have a flashlight, and if she opened the car door, the whole car would light up, so she thought it would be neat to have her paper light up instead. That night, Becky wondered how things could glow in the dark, like balls. She wrote a list of things that glow in the dark that are in nature and man made. She went to the hardware store with her dad and returned with a pail of phosphorescent paint and put a stack of paper in the bathroom. And there she experimented. She turned the lights on and off again and again, until she ran out telling her parents, 'It works! It works!' She used an acrylic board and coated it with a certain amount of phosphorescent paint, and when the board was exposed to light it glows. And it lights up the paper on top. Two years later, Becky received a patent.
