### A teambuilding activity related to the air we breathe

Objective:
From the materials provided, build a box with your team that will hold a cubic meter of air.

Materials:

• Strips of poster board
• Meter stick
• Stapler
• Tape

• Don’t give directions, just the goal (build a cubic meter)
• Work in groups of 3-4
• This activity needs a lot of space, especially if you are making several
• Do some preliminary work ahead of time, such as measuring the strips to be cut. (see below for directions for making a cubic meter box)

Supplemental Ideas for Teacher

1. Make a 1 cm3 box (holds 1 mL) and a 1000 cm3 box (holds 1 liter) for comparison with the studentâ€™s cubic meter box
2. Show the American Academy of Allergy, Asthma, and Immunology website. Show a local page with the current air quality conditions. Illustrate that air quality is measured in cubic meters (m3).
3. Relate the size of the cubic meter box to the air we breathe.
• A normal breath is 500 cm3.
• One cubic meter is 2000 breaths.
• An average person breathes 10-14 times a minute.
• It would take 3 hours and 20 minutes to breathe a cubic meter of air.
• The amount of air breathed by the average person typically ranges from 20-30 m3 per day. However, with heavy work and exercise this can easily exceed 50 m3 per day.

Directions for Making a Cubic Meter Box

• Cut each sheet of poster board into seven strips. Each strip should be 4 inches x 22 inches. Cut a total of 24 strips.
• Fold each strip in half lengthwise. You may want to make the fold against a straight edge, such as a yard stick or meter stick, to get a good crease.
• Staple two strips together to equal a meter (39 1/3″) in length. Overlap the excess. This will make a stronger box. Do this for the remaining strips. You should have 12 one-meter pieces when you are done.
• Place four pieces on the floor in a square. Staple together the corners. Do the same fo another four pieces.
• Turn each square on its side. Staple on the remaining four pieces to make the rest of the cube.
• Reinforce with masking tape, if needed (this is also a good way to include more children, whether or not the tape is really needed).
