Correction: new project

This is definitely the project I want to do. What I have now decided to do is explore how salt affects the boiling point of water. I was thinking i would do the experiment in a lab and am looking into it because i wanted to use a Bunsen burner, beakers etc.. or if not i would do the experiment in a pot on the stove and when the water reaches boiling point, i would see how the addition of salt, by gradually adding it after it has reached boiling point affects the temperature of the water. The independent variable is amount of salt added. I'll be controlling time and the dependent variable is temperature.
I have designed the experiment so i will measure the amount of salt initially so I make sure each time I add salt, it will be the same amount. After the water reaches boiling point (check with a thermometer), I will add salt, watch the thermometer as the temperature changes... recording results etc... and when I'm finished,I should have a set of results relating temperature of water to addition of salt. I will conduct the experiment several times to make sure it's right. Hopefully, it will all go well :D
