1. For this experiment, the independent variable is the temperature of the potato and hydrogen peroxide. The dependent variable is the reaction time in the test tube. This is determined by measuring the time it takes for the paper to float to the top of the test tube. The constants (control variables) are the amount of hydrogen peroxide used, amount of potato used and the size of the filter paper. 2. The potato is cut into small pieces and, together with some water, blended until it becomes soft. 3. The filter paper is cut into 8 pieces of small squares .....
