Properties of Hydrocarbons
Investigate how the size of a hydrocarbon molecule affects its boiling point, viscosity, and flammability.
About This Topic
Investigate how the size of a hydrocarbon molecule affects its boiling point, viscosity, and flammability.
Key Questions
- How does the length of a carbon chain affect the viscosity of a hydrocarbon?
- Why are shorter chain hydrocarbons generally better fuels?
- Explain the relationship between molecular size and boiling point in alkanes.

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.
