Does heating liquid water produce a new substance in the gas bubbles that appear?
Lesson Objectives...
Use mathematical and computational thinking by graphing mass vs. volume data for different substances and finding the ratio of mass to volume (a unit rate) (scale, proportion, quantity) for the samples measured to determine the density of different clear liquids.Â
Argue from evidence and critique two arguments on the same topic; strengthen these arguments by using additional empirical evidence (patterns) and scientific reasoning to support an explanation for whether the substances collected from the gas produced by the heated water is made of different types of particles or the same type of particles (patterns) as those in the water that we started with.

Density is determined as a ratio of mass to volume (a unit rate). It is constant (a property) for any sample of a substance, regardless of size.
The gas produced by the heated water is made of the same type of particles as those in the water that we started with.
