ILLUSTRATED SCIENCE MODEL · DENSITY COLUMN

Build a liquid density column: Choose liquids and objects

Household-liquid densities vary, so use a consistent recipe and handle each liquid carefully. The goal is to compare relative density, not simply to stack liquids by color. This authored animation illustrates the process; use real observations for measured results.
