INVESTIGATION 6

How might radon affect me?

NOTES TO TEACHER

PURPOSE: to explore the relationship between the respiratory system and the threat from indoor

radon exposure.

MATERIALS:

• Drinking straws

• Grease

• Masking tape

• Plastic dishpan

• Large empty plastic milk jugs with cap

• Measuring cup

• Rubber tubing

BACKGROUND:

Most people, including most students, have very little understanding of the phenomenon of radio-

activity and its effect on the human body. This is unfortunate, because radioactivity and radioactive

substances have become increasingly important in our daily lives.

In this investigation, students will explore the respiratory process and relate their own breathing

patterns to radon exposure.

WARM-UP:

Prior to initiating the lung capacity experiment,

demonstrate to students how the respiratory system

works and specifically demonstrate the role of the

diaphragm in the breathing process. To perform this

demonstration, you will need a two liter plastic bottle,

two round balloons, scissors, and two rubber bands.

Cut the bottle in half. Place one of the balloons

through the opening over the bottle. Stretch the

balloon opening over the bottle opening. Hold the

balloon in place with a rubber band. Think of this

balloon as the lungs. Cut the neck off the other

balloon. Stretch this balloon across the bottom of the

bottle. Hold the balloon in place with a rubber band.

Think of this balloon as the diaphragm. Pull down on

the stretched balloon. What happens to the balloon

inside the bottle? Explain to students how this action

is like that of the lungs and the diaphragm.
