The Science of Dissolving
Students will investigate which solids dissolve in water and which do not, and explore factors affecting dissolving.
Key Questions
- Analyze why some solids disappear in water while others do not.
- Compare the dissolving rates of sugar and salt in water.
- Predict if a new substance will dissolve in water based on its properties.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
