Chemistry Essential Questions
1. What are the physical models, symbolic notations, graphical models and
mathematical models that we use to represent, analyze, and communicate structure
and relationships in chemical systems and chemical interactions?
2. What observations about chemical systems and chemical interactions lead us to form
the physical, graphical, and mathematical models that we use to represent, analyze,
and communicate structure and relationships in chemical systems and chemical
interactions?
3. How do we use the physical models, symbolic notations, graphical models and
mathematical models of chemistry to represent, analyze, and communicate structure
and relationships in chemical systems and chemical interactions?
What are the models? From what observations do we infer these models? How do we
use these models?
