States of matter can be more than just your average solids, liquids and gases When water turns into snow, is it still water? The answer is yes! Our world is filled with solids, liquids, gases and even other matter that can go from one state of matter to another without changing its chemical substance. In this unit, students explore these different states of matter and their interactions. Students can make non-Newtonian fluids, observe how temperature and pressure affect matter, and explore solutions.
