Product Details

Exercise your students’ bodies—and their minds—to discover the essential relationship between breathing and cellular respiration! Students determine the relative amount of carbon dioxide in exhaled air before and after exercise using an acid–base indicator. Which sample contains a greater concentration of CO2? How and why do athletes train to increase their breathing efficiency? Students will answer these questions and explore the complex biofeedback mechanism by which the body uses the production of CO2 and pH to regulate breathing.

Performance Expectations

MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism
HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
HS-LS1-6. Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules.
