This science fair project was done to find out how the freezing point of water is affected by the presence of sugar or salt. The experiment was conducted using salt, sugar and water.
1. For this science fair project, the independent variable is the amount of salt and sugar added to the solution. The dependent variable is the freezing point of the solution, and will be measured with a thermometer. The constants (control variables) are the temperature of the environment (which will remain at room temperature), the amount of solution in each test tube and the temperature of the ice in the basin. 2. Mix 200g of salt into in 1 liter of water and pour the solution into ice cube trays. Place the trays in a freezer, and leave overnight. The ice .....
