Understanding States of Matter and Processes

This video lesson for third graders covers the physical properties of matter, including mass, volume, and temperature. It reviews the water cycle and explains the three states of matter: solid, liquid, and gas. The lesson includes practical examples and experiments to illustrate these concepts. Students are encouraged to practice describing matter and to prepare for an upcoming exam by recording themselves explaining the concepts.
