Water is a unique earth material, the only material on Earth that occurs naturally in all three states of matter, solid, liquid, and gas. Next to the air we breathe, water is probably the most important thing in our lives. Your child will learn these interesting things and more as we investigate water, its properties, and what it can do in the FOSS Water Module.

One of the goals of this module is to help students focus their observation skills on water-to begin seeing water in a new light. Through their investigations into the properties of water, how it reacts to heating and cooling, and the processes of evaporation and condensation, students will begin to appreciate how important this unique material is.
