This is a series of experiments that can be performed using regular household materials that allows students to explore the concept of states of matter. Part of this exploration is the concept that the reason that a material will change the state of matter (phase) is based on how much energy it has (the temperature) with experiments of what happens when we add heat or take away heat (cool down) solutions. Another part of the exploration is how solutions are made and what happens when solution types change (meaning how concentrated a solution happens to be) or what happens when the fluid part of a solution is allowed to evaporate or solidify. The evaporation process gives students an understanding of how salt mines and salt flats form from oceans and lakes or how oceans and seas can become more concentrated or more dilute based on the proportion of salts (or solids, solutes) to water (or liquid, solvent) within the solution.
These experiments can be conducted independently of each other or as a continuous pattern of exploration. Some of the experiments should be conducted over a period of days for observing change, while others can be conducted in as little as 1-hour of instruction time.
