Do objects with a lower density float or sink when paired with something of a higher density?
What is, lower density will float?
200
Does water vapour sink or float?
What is float? It will sit on top of fluid and escape a jar if possible.

we know that it is the volume of a __________.
What is a solid?

True or false: density is influenced by how closely particles are together
What is true? Closer = more dense, further apart = less dense

Why do solids usually sink in water?
What is, because it has a higher density? It has more particles and they are more closely packed together.

Even though wood and ice are solids (and should be more dense than liquids), they float on water. Why?
The density of wood and ice is actually less than the density of water.
