Finley seventh-graders in Donald Ingegno’s class recently conducted a liquid layers lab as part of their Density and Buoyancy unit. The students used honey, light corn syrup, dish soap, water, vegetable oil and rubbing alcohol, carefully layering each one to create a “science burrito.”

The class had learned to calculate density prior to the lab activity. According to Mr. Ingegno, the lab showed the students the secret behind density and reinforced that density is a measure of how much mass is contained in a given unit (grams per milliliter). Thus, heavier liquids are more dense and lighter liquids are less dense. The students used each liquid’s density to stack the layers of liquid and learned that liquids with the same volume can have different density.
