This experiment was performed to find out how temperature will affect the salinity and pH of seawater. 

Instructions preview
1. For this experiment, the independent variable is the temperature of the seawater – 20 °C, 25 °C, 30 °C, 35 °C, 40 °C, 45 °C, 50 °C, 55 °C, 60 °C and 65 °C. The dependent variable is the pH and specific gravity of the seawater. This is determined by using the pH paper and the hygrometer. The constants (control variables) are the size of the beaker, the amount of seawater used and the exposed surface area of the water. 2. Ten beakers are filled with seawater up to 10cm in height. The viscosity and pH levels of .....
