autobiography of pencil for class6 100 lines
Answers
I’m a pencil. I was born in a big factory. I have names like Atlas, Mango and Nataraj. I’m made of wood and graphite. I’m thin and long. They wrap my body in coloured paper. After that they pack me into a lorry, and the driver takes me to many book shops. I met many friends like rulers, erasers, pens and colour pencils.
Some children love me but some children don't. Some children get angry with me when the graphite point breaks. When I’m short some children throw me out. Some children keep me in a box. Doctors, singers and engineers came to their current positions with my help. I’m proud to be a pencil. I love to help children.
Answer:
The core of a pencil is made of graphite, clay, and water. During the 17th century, the graphite and clay were grounded down by hand, put into a cylindrical mold, and fired in a kiln. Today, pencils are mass-produced by machines that cut down the wood, insert the lead, and stamp or print a design.
We couldn't complete a crossword puzzle, sketch a masterpiece, or write the next great American novel without a good pencil. While it may seem like these writing instruments simply grow on trees, they require expert craftsmanship and engineering to be produced.
Since pencil's early days, the manufacturing system has more or less been the same. The graphite is grinded down and mixed with powdered clay and water to make a thick paste. This paste is put into a cylindrical mold and fired in a kiln. The result is a strong lead core that's difficult to break and extremely smooth for writing on paper.
A system for grading the graphite was eventually developed in the 1820s. Henry David Thoreau and his father John numbered the hardness of their pencils from #1 - #4. The softer the pencil, the more graphite it contained, resulting in a darker, smoother line. The firmer the pencil, the more clay it contained, meaning the lines would be lighter. The standard today, as any student can verify, is the reliable #2 model. The graphite in these pencils is at just the right amount of thickness to produce an easily readable mark.
With Thoreau's scale in place, America needed a way to keep up with the demand for high-quality pencils. In the 1870s, Joseph Dixon used his background in lithography to create machines that were capable of mass-producing pencils at a faster rate. The machines also pushed the pencil making process forward by cutting grooves for the graphite into the wood. Before then pencils had always been handmade with a flat, round design. With Dixon's machines, they were hexagonal and had attached erasers. His company could produce upwards of 80,000 a day, completely taking the industry to new heights.
