A quote from the module suggests that plants might have antibacterial properties:

Let students create blank data tables for collecting data. Let them write out their designs, share them. Let each student select what he or she feels is the best experimental design. Remind them of the difference between a laboratory activity and a laboratory experiment.
Decide then if they are going to continue with the module. You may decide to do that, or, you may prefer to do one or more of the student designs, or, you may wish to do the module and the student-designed experiments, of course paying attention to safety and budget, just like in real-world science. Remind students of government funding for science. Ask what kinds of research government should fund.
