5B -liquid density

We investigated the density of liquids today. Children carried out their own experiments to find out which liquids were the most dense. What is density? What are your thoughts about the statements below?

How could we test whether the temperature of a liquid effects the density?

  1. We could test whether the temperature of a liquid effects the density by using hot water and cold water to investigate the density of the two different temperatures.

  2. What is density?
    Density is how heavy something is.

    What are your thoughts about the statements below?

    The heavier the liquid is the denser it is.
    That is true because density means how heavy something is.

    They do not mix since they have the same density
    This is not true because that would mean that milk and oil would mix , and that food colouring and water would not mix.

    I think the milk is the densest because it contains cream.
    This is not true because our experiment showed that honey is the densest.

    The temperature of a liquid affects the density.
    This is true because honey and water does not mix but honey and hot water does mix.

  3. We could create to mixtures one that is cold water and one that is hot.
    We could also add one that could add hot and cold in the same mixture with the same amount .
