Density Rainbow Experiment Free Resource – STEM Scholars Hub

This activity explores the concept of density and how it governs the behavior of matter, providing students with hands-on experience in observing how liquids of different densities form distinct layers. By carefully layering liquids such as honey, water, and oil, students see how density influences whether substances float or sink and learn how to compute density using the formula: Density = Mass ÷ Volume. This allows them to connect calculations with observations, reinforcing understanding of mass, volume, buoyancy, and intermolecular forces. Students gain a deeper appreciation of how physical properties determine the behavior of matter in everyday phenomena.

This topic is ideal for students, teachers, and parents/guardians to explore physical science principles in a hands-on and engaging way. It is perfect for class demonstrations, small group experiments, homework, independent practice, or enrichment activities. Answer keys and supporting materials are provided for guided practice.
