Graphite is an essential tool in today’s world with its uses in writing, drawing, and electrical conductivity. Understanding how pencils are made is only part of the process and K-12 teachers need to educate their students about how graphite is made.
Graphite is a mineral that is formed through the metamorphosis of carbon-rich materials, such as coal and organic matter, under high pressure and temperature conditions. It is usually found in deposits around the world with the majority of it being extracted in China, India, and Brazil. The graphite is extracted through a process called open pit mining or underground mining depending on the location and the depth of the deposit.
Once the graphite is extracted, it needs to be processed to be suitable for use in different applications. The processing involves grinding the raw material into a fine powder and then purifying it through chemical and thermal treatments. This process can take weeks or even months but it is important to ensure the purity and refinement of the graphite.
After processing, the graphite is turned into the various forms we see in everyday life, such as pencils, electrodes, lubricants, and more. This conversion process involves mixing the purified graphite powder with binding materials before being molded into the required shape.
As educators, it is important to teach our students about the science and process behind the materials we use in everyday life. By teaching them about the extraction and processing of graphite, they will develop an appreciation for the resources that go into making things we take for granted. It will also help them to make informed decisions about the products they use and the impact that they have on our environment.
In conclusion, graphite is an essential material that is used in a variety of applications. Educating students about its origins and processing will not only help them understand the science behind it but will also lead to a better appreciation for the resources we consume. As K-12 teachers, it is our responsibility to provide students with this knowledge so that they can make informed decisions and contribute to a better world.
