Understanding the connection between mass and density can be confusing. Understanding density in liquids can be even more difficult. The sixth grade at GCA conducted a lab while studying measurement and physical properties of matter. Students performed the steps of the scientific method as they hypothesized, experimented, and recorded results in a lab report. Liquids that were used were shampoo, diswashing detergent, baby oil, water and corn syrup. Liquids moved as they were poured into places by density. The result was a tower of colorful, layered liquids.
