Science4Us begins the study of matter with everyday objects that students are comfortable with. The Materials and Mixtures module begins the unit. Students explore everyday objects they know like recyclables, identifying objects made of wood, cloth, plastic or metal.
Kindergarten through second grade students have experience with matter in its three states: solid, liquid and gas. In the States of Matter module, students further explore the unique properties used to characterize each phase, and learn that anything on earth that has mass and takes up space is matter.
The Changes in Matter module further explores the concepts from previous modules, and looks at how matter may be modified or changed. Through an instructional video, games, and activities, students explore three types of changes that occur in matter: physical change, in which only the shape of the matter changes; physical phase change in which matter changes to a different form (solid, liquid, or gas); and chemical change, in which matter is changed in a way that cannot be undone (fruits ripening or foods cooking).
