Scientific Method
Grade 9•45 minutes•Asking questions and defining problems: Asking
questions (science) and defining problems
(engineering) in 9–12 builds on K–8 experiences and
progresses to formulating, refining, and evaluating
empirically testable questions and design problems
using models and simulations.
• Ask questions that arise from examining models or a
theory, to clarify and/or seek additional information
and relationships.
2. Developing and using models
3. Planning and carrying out investigations
4. Analyzing and interpreting data
5. Using mathematics and computational thinking
6. Constructing explanations and designing solutions
7. Engaging in argument from evidence
8. Obtaining, evaluating, and communicating information
