Experiments
Here are experiments our science specialists have selected to support this IB* topic.
Cellular Respiration
Experiment #9 from Investigating Biology through Inquiry
In this Preliminary Activity, you will use a CO2 Gas Sensor to determine the respiration rate of peas. After completing the Preliminary Activity, you will first use reference sources to find out more about peas, seeds, germination, and cell respiration before you choose and investigate a researchable question dealing with the cell respiration. Some topics to consider in your reference search are:
- peas
- seeds
- germination
- cell respiration
- carbohydrates
- glucose
- dormant
Aerobic Respiration
Experiment #17 from Biology with Vernier
In this experiment, you will
- Measure changes in dissolved oxygen concentration.
- Study the effect of temperature on cellular respiration.
- Make a plot of the rate of cellular respiration as a function of temperature.
