Study Notes
Density Experiment
- Start with an empty glass and fill it with water mixed with food coloring.
- Gradually add syrup or treacle, and optionally more water to achieve a thicker layer.
- Top the glass with oil and allow it to settle for approximately 15 minutes.
Layer Formation
- Liquids separate into distinct layers based on their densities, which do not mix.
- Syrup has the highest density, settling at the bottom.
- Oil, being the least dense, rises to the top.
Object Density Testing
- Dropping a metal nut: Sinks to the bottom due to its high density.
- Dropping a grape: Sinks through oil and water but floats on syrup because syrup is denser.
- Dropping a plastic bottle top: Sinks slowly through oil and rests on the water layer.
- Dropping a sponge: Floats on the oil as it is less dense than the oil.
Additional Experimentation
- Encouraged to test various objects to discover their behavior in different fluids based on density.
- Shining a torch from above enhances visual effects in the layered liquids.
Conclusion
- This hands-on experiment demonstrates the concept of density effectively in a simple and engaging manner.
