Understanding Solutions
Students will investigate how some substances dissolve to form solutions and explore factors affecting solubility.
Key Questions
- Explain why some substances dissolve in water while others do not.
- Compare the properties of a solution to those of a suspension.
- Predict how changing the temperature of a solvent will affect the rate of dissolving.

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.
