Liquid Density Tower

Layer honey, dish soap, water and oil in a glass and measure the density of each liquid to explain the order.

Grade 7ExperimentScienceChemistryPhysicsMeasurementIntermediate40 to 60 min8 materialsAdult supervision required

What you'll learn

  • Calculate density as mass divided by volume
  • Predict which liquid floats on which using density
  • Describe why careful pouring and equal volumes matter

Objective

Measure mass and volume to calculate the density of several liquids, predict how they will layer, and test the prediction.
