I made this coloring sheet to help teach the respiratory system. This sheet has magnified alveoli to be colored. There is a portion of the coloring sheet in which the students must color the parts of the respiratory system. There is a portion of the sheet that requires the students to differentiate between normal passageways and those that are inflicted with asthma and pneumonia. The last portion requires the students to color three pictures in which the respiratory system interacts with other body systems.
