In the previous experiment we tried to find out just how adding salt to water before boiling it affected the time it took to boil water and its temperature. In this post we’ll discover how such a simple activity can be combined into a full scale science project. By merely increasing a few variables in the same experiment and performing it repeatedly with these variable you can have an attractive science project ready in no time at all.

The key to it all is taking a number of readings as you substitute the variable. Now you can just just salt or you can add different things such as sugar or vinegar to the boiling water. Or just take salt in different amounts such as one tablespoon or two or three for the different repetitions of the experiment. Make sure that you adjust the data recording and hypothesis according to your choice of variable.

Now do the actual experiment and keep good records. Remember you will be using the data you collect in tables to demonstrate the variable’s effect on the simple process of boiling water. You can draw conclusions based on the data that you collect and either support or modify your hypothesis so that it works for the science project. There’s a lot your can play around with, so have fun experimenting.
