Measuring the Effect of Increased Carbon dioxide Concentrations on Temperature
Research question: How does an increase in the concentration of Carbon dioxide affect
air temperature?
Variables:
Control:
Independent variable:
Hypothesis:
Materials:
Carbon dioxide probe
Temperature Probe
Vernier equipment
500 mL Erlenmeyer flask
stopper
Lamp
1 gram of baking soda
15 mL of vinegar
Hypothesis:
Procedure:
1) Set up one 500 mL Erlenmeyer flask. You will use the same flask for each
concentration of CO2 so be sure to go in order of increasing concentrations:
initial, 0.1 gram baking soda with 1.5 mL of vinegar and 0.5 grams of baking soda
with 7.5 mL vinegar, and Follow the set up in your preliminary laboratory.
2) Use the CO2 probe to measure the amount of CO2 in the initial bottle. Record this
number.
3) Place the stopper in the flask with the temperature probe in the flask. Turn on the
light and run for 15 minutes
4) React 0.1 grams of baking soda with 1.5 mL of vinegar.
5) Place the stopper in the flask with the temperature probe in the flask. Turn on the
light and run for 15 minutes
6) After the 15 minutes, measure the amount of CO2 present and record.
7) React 0.5 grams of baking soda with 7.5 mL of vinegar in your second bottle..
8) Place the stopper in the flask with the temperature probe in the flask. Turn on the
light and run for 15 minutes.
9) After the 15 minutes, measure the amount of CO2 present and record.
