Physics
Density and Polarity – Oil and Water Lava Lamp
Immiscible liquids and density.
Step-by-Step Instructions
1
Add food colouring – drops pass through oil into water.
Observations
: Water and oil separate due to density and polarity differences. The tablet releases CO₂ bubbles that rise, carrying coloured water, then fall as gas escapes – demonstrating convection and chemical reactions.
Hypothesis
Oil and water will not mix, and adding an effervescent tablet will create bubbles that move coloured water through the oil.
Conclusion
Polarity (water is polar, oil is non-polar).
