Density Tower Experiment Worksheet

Science experiments lesson 2: Density tower: honey, water and oil · Set 489 · 40 questions

What you do (Heaviest for its size sinks): 1. Pour honey slowly into the glass to fill about a quarter. 2. Pour coloured water gently down the side of the glass. 3. Pour the cooking oil gently on top and watch the layers settle. 4. Gently drop in a cork and a coin, see where each stops, and wipe up oil spills.
