Display the map in the hall for others to see. Invisible Pollutants Experiment Divide the class into three groups. Each group sets up a bean plant garden with three containers, each container having one bean plant each. Students determine and compare the pH of the three solutions and predict how the plants will be affected by each solution. Record pH and predictions in journal.
Procedure is recorded in journal.
Observe plants daily. Record in journal what happens to each plant. Sketches may be part of the observations. Compare plants and discuss observations at the end of a day, week, two weeks, or until plants die. Using the observations of all groups, write a class conclusion for this experiment.
