  1. Artificial Valves

  2. Artificial Valves In this activity you will be able to see for yourself the way in which a valve works. This activity will offer: • An opportunity to build a model of a valve. • A chance to observe fluid moving through a one-way valve. • An opportunity to learn more about biotechnology design. Let’s Get Started!!

  3. Procedures • Use a pair of scissors to cut off one of the fingers from the glove. TOP

  4. Procedures • Cut an "X" in the tip, with each slit about one inch in length. SEE DIAGRAM B & C. • Insert the glove finger into one section of wide, clear plastic tubing. Invert and roll a small section of the fabric of the glove back over the tube to form a collar. • Secure the exposed collar to the plastic tube with either duct tape or an elastic band. SEE DIAGRAM E. • Place the other tube section on top of the balloon end of this tube. TOP

  5. Procedures • Use duct tape to secure and form a waterproof seal around the joined edges of the two tubes. SEE DIAGRAM F. • Fill a small cup with water. Over a sink, carefully pour the water into the tube assembly so that it flows into the inside of the glove finger (Labeled "TOP" in diagram). Observe what happens as the fluid impacts the glove finger. • Turn the tube assembly upside down and again pour a cup of water into the tube. What happens this time? Write down your observations. TOP

  6. What’s Next?? • Answer the questions at the end of the activity. • Follow your teacher’s instructions for sharing results. • Return materials, and, CLEAN UP.
