Matter: Solids, Liquids, and Gases

Students learn fundamental concepts about matter and overcome common misconceptions through a series of engaging investigations, each followed by a lively discussion based on evidence they have gathered. The activities in this guide help teachers build a foundation of inquisitiveness and develop solid science concepts in students. Activities reinforce an understanding of the states of matter, as students examine real-world materials, some resistant to categorization, and find ways to define each as solid, liquid or gas.
