Question

According to this experiment, summarize it and be sure to address the following questions:

What hypothesis was being tested? How did you test your hypothesis? What independent and dependent variables were being investigated? What controls did you use? What were possible sources of error in your experiment? Please explain how the experiment you conducted supported or failed to support the original hypothesis.

Respiration charber Procedure 1. Three respiration chambers like the one depicted in figure three will be prepared for you. Each chamber will contain 15g of either glass beads, germinating beans, or non-germinating beans (the NaOH and other components will be the same in each chamber. The cotton plug may or may not be present). Cotton plug Stopper Graduated pipette Germinating/non-germinating beans or glass beads NaOH Figure 3: Respiration chamber with peas. 2. For each chamber, inject a drop of colored water in the end of the pipettes and let the drop fall to the "0" mark on the pipette (or as close as possible). Carefully insert the pipettes into the rubber stoppers. It is important to make sure that the chamber is sealed tightly in order to prevent gas entry/escape. Your instructor may advise you to wrap the plug with parafilm so that the only gas that can enter or leave the chamber has to travel through the pipette. 3. Place the apparatus in a horizontal position. 4. Record the position of the water every 5 minutes for 30 minutes in each chamber. Note: Depending on the rate of respiration, your colored liquid may reach the end of the pipette before thirty minutes. Be sure to watch it carefully and stop recording when the colored water nears the end of the tube. Note its position and the time elapsed. 5. Graph the results in Figure 4. Note: You may use a slightly different method. Consult your instructor. gila8s bee Negatire keast ealtivi Cellular Respiration and Fermentation 85 © bluedoor, L 1 רךכ
