PanAdded Water?Froze the pan?1yesyes2yesno3noyes4nono
Then she compares the clay in all four of her pans. The clay in pan #4 was the same at the end of the experiment as it has been at the beginning. The clay in pan #1 had changed and broken up more than the others. 

Which of the following conclusions could Patsy have made?

Frozen clay takes up more space than thawed clay does.

Adding water to clay and then freezing it helps plants to grow in the clay more than either freezing it or adding water to it alone.
