Blow some bubbles and learn how living things need air in the eighth lesson of this series. Young scientists investigate this important gas by observing bubbles and monitoring their own breathing. A simple and fun activity that raises awareness that even though we might not be able to see it, air is everywhere, and we need it to live. To extend the lesson, have students compare their breathing while at rest and after doing a simple exercise, discussing how our bodies need more oxygen when it works harder.
