Here are experiments our science specialists have selected to support the IB* topic.
Experiment #12 from Investigating Biology through Inquiry
In the Preliminary Activity, you will use a spectrophotometer to measure color changes in DPIP due to photosynthesis by chloroplasts.
After completing the Preliminary Activity, you will first use reference sources to find out more about photosynthesis by chloroplasts before you choose and investigate a researchable question dealing with photosynthesis. Some topics to consider in your reference search are:
- electron transport chain
Experiment #7 from Biology with Vernier
In this experiment, you will
- Use a Spectrometer or Colorimeter to measure color changes due to photosynthesis.
- Study the effect of light on photosynthesis.
- Study the effect that the boiling of plant cells has on photosynthesis.
- Compare the rates of photosynthesis for plants in different light conditions.
