Description
This experiment was performed to find out the effect of carbon dioxide on the pH level of water. Human activities such as deforestation and the burning of fossil fuel increases the level of carbon dioxide in our atmosphere. The results of this experiment will show the effects of an increased carbon dioxide level on our oceans' acidity levels.

*For this experiment, the independent variable is the concentration of the carbon dioxide- which differs between the concentration of CO2 in the air expelled from our lungs versus the concentration of CO2 contained in the smoke from a car exhaust. The dependent variable is the level of acidity in the water. This is determined by measuring using a pH paper. The constants (control variables) are the type of water used (i.e. tap water, sea water etc), the amount of water and the time air is forced/blown into the water. *The water bottle is filled with 1 liter of tap .....
