1. The independent variable for this experiement is the location at which the water sample is taken. The dependent variable is the pH reading, turbidity, ammonia content and the nitrate content of the water sample. This is determined using the pH paper, turbidity meter and the freshwater test kit. The constant(control variables) are the amount of the water in each sample. 2. The independent variable for this experiment is the location at which the water sample is taken (ie: upstream or downstream). The dependent variable is the pH reading, turbidity, ammonia content and the nitrate content of the water ..... |
