Sure, here is a step-by-step plan to investigate the amount of carbon dioxide in the air athletes breathe out after they have been running at different speeds using green BTB solution:

1. **Preparation of Materials**: Gather all necessary materials including green BTB solution, test tubes, stoppers, straws, a stopwatch, and athletes.

2. **Control Variables**: The two variables that need to be controlled in this experiment are the volume of the athlete's breath and the duration of exercise. Ensure that each athlete blows the same volume of air into the test tube by using a measuring device or by standardizing the number of breaths. The duration of exercise should also be standardized, for example, each athlete should run for the same amount of time at their respective speeds.

3. **Exercise**: Have the athletes run at different speeds. It's important to note the speed at which each athlete is running as this is the independent variable in the experiment.

4. **Collection of Exhaled Air**: After running, immediately have each athlete blow air through a straw into a test tube containing green BTB solution. The BTB solution is an
