In many cook books we read the preliminary instruction which says add salt to water before boiling it. Finding out why is going to be the aim of this science experiment. Does adding the salt to the water make it boil faster? Or does adding salt to the water make it boil at a higher temperature which may be required for the recipe? That’s what you will hope to find out as you perform this science experiment.

What all will you need for this process? Table salt, naturally, and distilled water so that no other factor affects the boiling temperature. Plus you will need a thermometer to check accurately just what the temperature of the boiling water is. And of course a timer to check how soon the water boiled. You will also need a spoon to shovel the salt into the water. And of course a container in which the water will be boiled.

Now make sure that an adult is aware that you are performing the experiment as the heating the water is potentially dangerous. It would be best to enlist your parent’s help as you set about doing this experiment. First you need to boil a cup of water without salt and see how long it took to reach boiling point. Measure the temperature with care. In the second round you add a tablespoon of salt to the water and make the same recordings. Now you will be able to reach the right result for your science project.
