 communicating scientifically At first the salt just sank but after about a half of a minute of stirring It dissolved. How did the water and salt change when they were combined in the cup? They were only combined in a cup. How did measurement help you describe the changes? 5 cc of salt equals 1 graham of salt and it adds to the weight of the water even when dissolved and the salts weight dose not change when dissolved. What have you learned about the properties of salt when you add it to water? I reviewed that salt dissolves in water and the water stays clear. How does experimenting with a solution of salt and water help you understand the properties of salt and/or water? It actually doesn’t for me.
