Get Energized with Cellular Respiration!
- Understand the purpose and mechanism of cellular respiration
- Determine the relationship between breathing (respiration) and cellular respiration
- Analyze graphs of experimentally-recorded data
OverviewIn this fun lesson plan, students will measure how the amount of carbon dioxide in their exhaled breath changes with exercise levels. Carbon dioxide is a product of cellular respiration, so the lesson highlights how breathing is connected to cellular respiration and energy production in our body. They will make the measurements using a simple colorimetric test and a phone with Google's Science Journal app.
