WHAT’S YOUR LUNG VOLUME EXPERIMENT

You will need:

  • Clean plastic tubing
  • A large plastic bottle
  • Water
  • Kitchen sink or large water basin

Steps:

  1. Make sure the plastic tubing is clean.
  2. Put about 10cm of water into your kitchen sink.
  3. Fill the plastic bottle right to the top with water.
  4. Put your hand over the top of the bottle to stop water escaping when you turn it upside down.
  5. Turn the bottle upside down. Place the top of the bottle under the water in the sink before removing your hand.
  6. Push one end of the plastic tube into the bottle.
  7. Take a big breath in without the tube in your mouth.
  8. Then put the tube in your mouth and breathe out as much air as you can through the tube.
  9. Measure the volume of air your lungs had in them.
  10. Make sure you clean up the area to finish.
