In 2.9 S2, you should be able to discuss the "Design of experiments to investigate the effect of limiting factors on photosynthesis".
This isn't particularly hard but is often used for analysis of data questions on exams.
This exercise should help prepare you for this.
This will NOT take a quick 5 minutes.

1. Run the experiment with all 4 of the available plants in each condition. (You can click and drag the plants and equipment to the front table)
2. Click on the timer to run the experiment
3. Record the results in a table.
When you have finished collecting results, answer these questions:
1. List the independent, dependent and control variables for each experiment you model. Discuss the validity, reliability and precision of the results. Use this to help.
2. Which plant had the highest rate of transpiration overall? What adaptations might this plant have that might explain this?
3. Explain and compare the effect of each environmental variable.
Present your results and analysis of data on your blog.
