1. For this science fair project, the independent variable is the type of coating on the marble tile – one tile will not have any coating, one will be coated with an industrial sealant, and the last, with calcium oxalate. The dependent variable is the weight of the marble tiles in acid solution over time, and will be measured using a digital weighing scale. The constants (control variables) are the acidity of the vinegar solution, the amount of vinegar used, the initial weight of the marble tile and the length of time the science fair project is conducted for. .....
