I have a question regarding the use of a hydrometer for a density/rainbow jar activity in a summer program. The activity involves a jar filled with water, which will be followed by additional substances, some of which we brew with. Corn syrup, food coloring, honey, and a few others.
I'd like to involve the concept of gravity/density in the activity. I want the kids to use hydrometers to analyze the gravity/density of substances as they are added. However, they will not be shaking the jar to mix the substances, and as a result there will be layers.
So, to my question: will the hydrometer read the gravity properly given the rainbow layers, or do the substances need to be mixed?
Thanks!
