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.
