Experiment design:

Overview of procedures:

We will maintain 48 twelve ounce cups with gavel and plant clippings, exposed to light 24 hours a day. We will observe the growth of algae.

  • Sample size: 48 twelve ounce cups of water, gravel, and aquarium plant clippings (24 experiment, 24 control) using the same species of plant.
  • Tap water will be used throughout the experiment. It will be treated with API Tap Water Conditioner to remove chlorine and hard metals.
  • Duration: To be decided - we plan to run the experiment through May.
  • Double blind studyPop-up glossary definition.; we do not know which water jug, A or B, is filled with the microwaved water.
