Description:

Students begin with interactive activities to develop a basic understanding of why cells need oxygen and need to get rid of carbon dioxide, how the circulatory and respiratory systems cooperate to bring oxygen and remove carbon dioxide from cells all over the body, and how the nervous system regulates breathing. Then, students carry out an experiment to test whether changing levels of oxygen and carbon dioxide influence how long they can hold their breath.
