In this experiment, you are working with available planter pots from the laboratory. You have choices of clay pots of different sizes, as well as biodegradable peat pots and others within lab equipment provided. To establish a standardized variable, you would

The scientific experiments require proper procedure and methodology to explain the particular phenomena that needs to be study during teh research.
