Wax is an essential part of our daily lives, from candles to crayons to skincare products. It’s a versatile material that has been used for thousands of years, but many students may not know how it’s made or where it comes from. By teaching students about how wax is made, you can help them understand the value of this unique material and its many uses.
To begin, it’s important to explain what wax is. Wax is a type of organic compound that is solid at room temperature but melts when heated. It’s made up of long chains of hydrocarbons, which are molecules that contain hydrogen and carbon atoms. These chains give wax its unique properties, such as its ability to repel water and resist heat.
There are many different types of wax, each with their own unique properties and uses. Some of the most common types are beeswax, paraffin wax, and soy wax. Beeswax is made by honeybees and is often used in candles and lip balms. Paraffin wax is made from petroleum and is often used in candles, crayons, and waxed paper. Soy wax is made from soybeans and is often used in candles and skincare products.
To make wax, there are two main methods: chemical synthesis and natural extraction. Chemical synthesis involves creating wax from petroleum or other chemicals, while natural extraction involves harvesting wax from natural sources. Beeswax, for example, is harvested by beekeepers who collect honey and remove the wax caps from the honeycomb. The wax is then melted down and used in various products.
In the classroom, you can teach students about the process of making wax by conducting a hands-on activity. One fun and easy way to make wax is by melting down crayons. Simply gather a selection of crayons, remove the paper wrappers, and melt them down in a double boiler. Once melted, pour the wax into a mold or container and let it cool and solidify. This activity is a great way to show students how wax can be manipulated and used for different purposes.
