What did you observe when the salt and water were combined?
Well the salt dissolved in the water and made a solution but we never mixed it enough so there was always a little bit of salt but when we put it through the filter all that you could see were bubbles.
How did the water and the salt change when they were combined in the cup?
Well the salt changed because you could barely see it and the water got bubbles after a round through the filter.
How did measurement help you describe the changes?
I will not answer this one
What have you learned about the properties of salt when you add it to water?
It has the property of dissolve you cannot see after you stir it enough in water.
How does experimenting with a solution of salt and water help you to understand the properties of salt and/or water?
Because some properties you can only see when it is mixed with something else.
