States of Matter and Phase Changes

This video tutorial covers the states of matter, including solids, liquids, and gases. It explains their properties, how they differ, and the processes of evaporation and condensation. The lesson includes vocabulary definitions, phase changes, and an interactive activity to categorize objects based on their state. The video concludes with a recap of the main points and encourages students to review the material and take a quiz.
