Synthetic materials are formed when humans deliberately mix substances together for the express purpose of creating new materials with desirable properties. Most synthetic materials are the result of chemical reactions during which the atomic structures of the original substances are rearranged to form the new material. Common examples of synthetic materials are plastics and fabrics such as nylon.
To better understand synthetic materials…
LET’S BREAK IT DOWN!
Natural resources are useful raw materials that we get from the Earth. They occur naturally, which means that humans did not make them using a mixture or chemical reaction. Humans use natural resources to form new substances that will be beneficial to us.
Plastics are synthetic materials that are very useful in our daily world. Plastics can be shaped when they are soft and formed into numerous different shapes that later harden. Humans have learned how to make plastics from a variety of substances, but the most common plastics today are made from fossil fuels like petroleum. Since World War II, the use of plastics has taken off in our country and in our world; you can find plastics almost everywhere.
In a chemical reaction, the atoms in the starting substances interact with one another. This often results in the molecules from at least one of the original substances breaking apart, allowing the atoms to rearrange and join together differently. This creates new substances that are called products. The number of atoms of each type is the same before and after a reaction.
