What is the big deal about climbing Mt. Everest without Oxygen?

Directions

  1. Take out a sheet of notebook paper. Write your name, date, and grade on the first three lines. Title your paper Asia: Mt. Everest_Science

  2. Skip a line and write #1. Next to #1, write your response to the following question. Make sure to include supporting details from the reading passage.

If you were a mountain climber, would you decide to use oxygen?

Watch the following videos on the right to learn more information about climbers and their journey up Mt. Everest.

  • Mt. Everest without Oxygen: Climbers Point of View
  • CBS This Morning: Snapchatting Climbers
  1. After watching the videos, skip a line after your last entry on your paper and write #2.

  2. Next to #2, answer the following questions in complete sentences.

    • What percentage of Mt. Everest climbers try to reach the summit without supplemental oxygen?
    • Why do professions climbers Adrian Ballinger and Cory Richards attempt to do so without it?

  3. Skip a line and write #3. Provide a written explanation for your classmates as to the dangers of climbers without bottled oxygen.
     
  4. Research how different heights affect the levels of oxygen. Now, draw a graph or at table that shows the amounts of oxygen available at different altitudes.

Diagram

On a separate sheet of paper, draw a diagram of the human respiratory system, as shown below.

Model

Human Lungs Model Use the following link to guide you in creating a working model of human lungs.
Model of Human Lungs

Supplies:

  • Plastic water bottle
  • 2 balloons

Directions:

Creating a model lung is pretty simple.  You can find directions all over the internet, including right here!

  1. Start with a plastic bottle, any size will do.  (Pictured here is a water bottle, but 2 liter bottles work as well).

  2. Cut the bottom off the bottle.  If you're having students make their own lung, you may want to do this for them, and if the students are young, you may want to tape over the cut edge so no one gets cut.

  3. Place a balloon in the neck of the bottle, and stretch the opening of the balloon over the opening of the bottle (see the blue balloon in the above photo).

  4. Cut the narrow part off of a second balloon.  Stretch the remaining balloon over the bottom of the bottle.

That's it!

Now to use it....

  • The blue balloon represents a lung.  The red balloon is the diaphragm.

  • When you breathe in, the diaphragm contracts (pull the diaphragm balloon down).  This lowers the air pressure in the chest cavity (because there's more room) and air fills the lungs.

  • When you exhale, the diaphragm relaxes (release the balloon, you can even push up on it a little).  The air pressure in the chest cavity increases and air flows out of the lungs.

Once you have finished creating your model, take a picture of yourself with it to submit as an artifact.

Don’t forget to place this completed activity/product into the pocket of your white Journey into Reading envelope.
