The apparatus shown below measures the oxygen consumed by a small animal. As oxygen is consumed, the water droplet moves closer to the flask. Because carbon
dioxide is absorbed by the potassium hydroxide solution on the filter paper, it does not affect the results.
1. You are performing a lab in biology class to determine, quantitatively, if
temperature affects the rate of oxygen consumption by a small animal. You will be testing the oxygen consumption of the animal at 0°C, 15°C, and 30°C. Write a prediction about the relationship between oxygen consumption and temperature. (1 point)
2. Using this apparatus, or a similar one, write a procedure to test your
prediction. Procedures should be detailed, specific, and written in numbered point form. (2 points)
3. State the manipulated variable, responding variable, and at least two
controlled variables for this experiment. (2 points)
