Mixtures vs. Solutions


In our science lab today we compared Mixtures and solutions. We learned that a mixture is a combination of 2 or more substances that are not chemically combined, while solutions are homogeneous mixtures that are evenly mixed. First we mixed crystal light and water to make our solution (ice tea drink). Then we mixed, Cheerios, raisins, Marshmallows, and M&M's in a big bowl. Each student was served one cup of our snack mix and was asked to count the different food items. Our solution was evenly mixed, or homogeneous and no particles were detected. However our mixture was not evenly mixed and each student got a different number of food particles.... There was a sad marshmallow in Jake's cup, and only 4 M&M's in Annabelle's, While Zack had 26....
