In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons. Learners are also encouraged to determine how the amount of air in a balloon changes as you vary the size of the hole you blow through.
Safety note: Check for latex allergies before purchasing balloons. Learners with respiratory problems should not breathe through the straws or blow up the balloons, but they can help record measurements and collect data.
