Plastic
We use plastic wrap to protect our foods. We put our garbage in plastic bags or plastic cans. We sit on plastic chairs, play with plastic toys, drink from plastic cups, and wash our hair with shampoo from plastic bottles. Plastic does not grow in nature. It is made by mixing certain things together. Plastic was first made in the 1860s from plants. That plastic was soft and burned easily. The first modern plastics were made in the 1930s. Over the years, hundreds of different plastics have been developed. There is a plastic for almost every need. Scientists continue to experiment with plastics. They hope to find even more ways to use them.
