Experiment 2: The Effect of Air Pollution on Seed Germination

I need the attached lab assignment completed:

In this experiment, you will test the effect of ammonia fumes on lettuce seed germination. This will be tested by adding an ammonia-soaked cotton ball to a resealable bag with lettuce seeds for one week and comparing the resulting germination rate to the rate of lettuce seeds in a separate resealable bag with a water-soaked cotton ball.
