Description
Cellular respiration lab activity using red cabbage indicator to detect carbon dioxide production: In this hands-on biology lab, students observe gas exchange during cellular respiration and compare carbon dioxide release from germinating and dormant seeds. This classroom experiment uses a simple red cabbage juice indicator to clearly demonstrate carbon dioxide production.
Cellular respiration can be difficult for students to visualize. In this lab activity, students observe the gas exchange that occurs during cellular respiration by using a red cabbage juice indicator to detect carbon dioxide. The indicator changes color when carbon dioxide dissolves in the solution, allowing students to see evidence of respiration taking place.
Students also investigate whether plants carry out the same gas exchange as animals. By comparing germinating peas and dormant seeds, students can observe differences in carbon dioxide production and better understand how cellular respiration occurs in living organisms.
This lab is easy to set up, inexpensive to conduct, and produces clear visual results that help reinforce one of the most challenging concepts in biology.
Purpose:
- Observe the release of carbon dioxide during cellular respiration
- Determine whether plants carry out the same gas exchange as animals
- Observe and analyze the color change of a natural acid base indicator
Materials List:
- Cabbage juice indicator
- Test tubes
- Drinking straws
- Cotton balls
- Graduated cylinder
- Germinated peas
- Dry peas
- Rubber stoppers

Reviews
YESSSSS - "my students tend to think that plants photosynthesize and only animals respire" - my students did as well! I'm delighted this lab worked so well for you. Kids are always amazed by the red cabbage juide.
