Separating Mixtures: Evaporation
Exploring evaporation as a method to separate a dissolved solid from a liquid, such as salt from water.
Key Questions
- Explain how evaporation can be used to recover a dissolved solid.
- Analyze the limitations of using evaporation for all types of mixtures.
- Design an experiment to recover salt from a saltwater solution.

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.
