Practice #1 Asking Questions and Defining Problems

# data[].attributes.body
-Questions are the engine that drive science and engineering.
-Students need the ability to ask well-formulate questions that can be investigated empirically

# data[].attributes.body
-Scientists construct mental and conceptual models of phenomena
- Models are tools for thinking with, making predictions, and making sense of experience.
-Engineers to analyze existing systems, visualize a design, to communicate design features, and as prototypes.
