| 1. For this science fair project, the independent variable is the acidity of the water used for the experiment (pH 5.0, 6.0 and 7.0) and the type of algae – spirogyra, green algae and red algae. The dependent variable is how the algae responds and how well it thrives in the acidic solution. This is determined by observing the algae over a period of time. The constants (control variables) are the amount of water used, the amount of sunlight and the type of algae used. 2. The 9 beakers are separated into 3 groups and labeled as “spirogyra”, “green ..... | ||
