Imagine you wanted to know the density of an object.
You DON’T have a triple beam balance to measure mass.
You DON’T have graduated cylinder to measure VOLUME.
YOU ONLY HAVE a glass of water. What could you discover about the density of your object?
Do Now Answer:
If you place the object in a glass of water and it sinks, then you know the density has to be larger than the density of water which is 1g/mL.
If the object floats, then it's density is smaller than the density of water (1g/mL) so it will be smaller than 1g/mL.
