Platinum is a precious metal that has a long and storied history. It is valued for its rarity, luster, and versatility, and is used in a wide range of applications, from jewelry to electronics to catalytic converters. Teaching students about platinum can be an exciting and engaging topic, as it touches on science, history, economics, and environmental issues.
To introduce students to the topic of platinum, it is helpful to start with some basic facts. Platinum is a naturally occurring element that is found in the Earth’s crust. It is dense, malleable, and ductile, and has a melting point of 1,768°C, which makes it difficult to work with but also highly valuable. Platinum is often found in association with other metals, such as palladium, rhodium, and nickel, and is most commonly mined in Russia, South Africa, and Canada.
Once students have a basic understanding of what platinum is, it is important to delve into its many uses and applications. Platinum is most commonly associated with jewelry, where its durability and shine make it a popular choice for engagement rings, earrings, and other accessories. However, platinum is also used in a wide range of other industries, such as automotive manufacturing, where it is used in catalytic converters to reduce emissions from vehicles. Platinum is also used in electronics, where it serves as a conductive material in electrical contacts and circuitry.
In addition to its many uses, platinum also has an interesting economic and environmental story. Platinum has historically been a valuable commodity, with prices fluctuating based on supply and demand. During World War II, platinum was used to create fuel cells for submarines, which led to a surge in demand and a subsequent spike in prices. Today, environmental regulations have led to an increased demand for platinum in catalytic converters, which has driven up prices once again.
Finally, teaching students about platinum can also be an opportunity to discuss environmental issues and sustainability. Platinum mining has been associated with a range of environmental and social issues, including deforestation, water pollution, and human rights abuses. As a result, there has been a growing movement to promote responsible sourcing and recycling of platinum and other precious metals.
Overall, teaching students about platinum can be an engaging and educational topic that touches on a range of subjects, from science to economics to environmental issues. By providing students with a deeper understanding of this precious metal, they will be better equipped to navigate the world around them and make informed decisions about their own lives and the environment.
