11. Physical Changes Example# 1: Cutting: Cutting makes a piece of paper smaller, but the paper is still paper.

12. Physical Changes Example #2 Knitting Knitting a wool cap. The thick wool is cut from sheep in spring. The wool is combed into soft strands, which are pulled into threads and twisted to make yarn. A knitter then knits the wool yarn into a cap. In the cap, the wool looks different from the way it looked on the sheep, but it is still wool.

13. Physical Changes Example # 3: Mixture A mixture is a substance that is made up of two or more kinds of matter. You put different types of matter together, but no new types of matter are formed.
