Study #1 - Matthew submerged a wad of chewed gum wrapped in its wrapper in a jar of water and observed it for about a week (until I couldn't stand it sitting on my counter any more!).
Study #2 - Matthew combined three ice cubes in a glass of water by stirring and then froze the all the contents of the glass for about a week (until I couldn't stand the glass in the freezer any more . . . Do you see the trend?).
Study #3 - Matthew combined a cup of sugar and about three cups of water in a container and then froze it.
Noting that he hadn't been very good about tracking and observing the progress of his experiments in the past, he decided that he would observe this one for five days. Probably the greatest outcome of this experiment the chart he made to track his progress.
Matthew hasn't decided on his next experiment, but maybe we'll provide a little more direction for his experiment designs. That is, if he'll take it.
