Which Freezes Faster? Water or Salt Water?
Freezing time and freezing temperature of different liquids are among the most important physical properties of that liquid. These physical properties may change when other material are dissolved in or mixed with liquids. This project will discover this subject using water and salt that are both safe and available in most households.
 Material and instructions:
What do you think about the freezing time of water and  salt water? Do some study, identify the variables and propose a hypothesis. Finally design an experiment to test your hypothesis.
