  Passage 7

  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 doesn’t grow in nature. It is made by mixing certain things

  together. We call it a produced

  or manufactured material. Plastic was first made in the 1860s from plants,

  such as wood and cotton. That

  plastic was soft and burned easily.

  The first modern plastics were made in 1930s. Most clear plastic starts out

  as thick, black oil.

  That plastic coating inside a pan begins as natural gas.

  Over the years, hundreds of different plastics have been developed. Some

  are hard and strong. Some

  are soft and bendable. Some are clear. Some are many-colored. There is a

  plastic for almost every need.

  Scientists continue to experiment with plastics. They hope to find even

  ways to use them! (160 words)
