Students will learn about the respiratory system by following Otwo (the oxygen molecule) as he goes from bouncing around in the outside air into the human body! After reading the story, students will complete two worksheets (multiple choice and short answer) to access their understanding. Answer keys provided.
– In one minute, how much air do you breathe in?
– What does nose hair do?
– What is a bronchial tree?
– Do you breathe in carbon monoxide or carbon dioxide?
Students will learn the answers to these questions and others as they color and read the pages of ‘Your Respiratory System Coloring Book’.
