  3. 3. Making a Lung Model <ul><li>Cut a 6” x 6” square of plastic sheeting from a garbage bag. I fold the bag so that I can cut several squares at once. </li></ul><ul><li>Fold each square in half. </li></ul><ul><li>The next slide will show you how to attach the tape handle. </li></ul>

Any narrow, blunt object will make this task easier. </li></ul>
  6. 6. Making a Lung Model <ul><li>Cut about 3-4 inches off the end of a bendy straw. </li></ul><ul><li>Insert the straw into the balloon. The balloon forms an air tight seal between the straw and the hole. </li></ul>
