Turn abstract chemistry into a memorable hands-on experience with this Density Tower Lab. Designed for grades 4–6, this activity shows students how liquids and solids behave based on their density, making particle theory both visible and engaging. Students layer liquids such as honey, dish soap, water, and oil in a clear jar, then test different solids (coin, bead, paperclip, grape, popcorn kernel) to see where each one settles. By observing the separation of liquids and the placement of so
