3. Knowledge Carbon Cycle LP Discourse Practice Carbon Cycle Learning Progression Framework

4. Knowledge Carbon Cycle LP Discourse Practice Carbon Cycle Learning Progression Framework Level 1: Force-Dynamic Level 4: Principles

5. Knowledge Carbon Cycle LP Discourse Practice Carbon Cycle Learning Progression Framework Level 1: Actors and events Level 4: Processes that generate, transform, and oxidize organic carbon

6. Lower and Upper Anchor Knowledge

7. Knowledge Carbon Cycle LP Discourse Practice Carbon Cycle Learning Progression Framework Inquiry: Investigating Accounts: Explaining, Predicting Citizenship: Decision-Making

8. Units of Analysis Learning Performances: the characteristics of students who are at a particular Level of Achievement and reasoning about a particular practice, process, and principle.

9. Units of Analysis Learning Performances: the specific practices characteristic of students who are at a particular Level of Achievement and reasoning about a particular practice, process, and principle. Accounts of processes: Example: Explanation of matter during photosynthesis

10. Current “Structure-First” Learning Progression Level 4: Principled Accounts of Processes in a Hierarchy of Scales (successful constraints) Level 3: Detailed narratives with unsuccessful constraints Level 2: Hidden mechanisms about events Level 1: Macroscopic Force-Dynamic Narratives about Actors and Events

11. Desired “Principles-First” Learning Progression Level 4: Principled Accounts of Processes in a Hierarchy of Scales (successful constraints) Level 3: Detailed narratives with unsuccessful constraints Level 3: Principled accounts at molecular scale w/ few chemical details Level 2: Hidden mechanisms about events Level 2: Successful conservation at macroscopic scale Level 1: Macroscopic Force-Dynamic Narratives about Actors and Events

12. Aspects of Starting Knowledge Level 1 • Visible Event • Accomplished byActors • WithPowers or Abilities • Trying to achievePurposes Needs or Enablers Results: Achieving Purpose

13. Aspects of Starting Knowledge Level 4 • Process • Occurs inSystems • Hierarchically Organized byScales • FollowsPrinciples: • Conservation of matter • Conservation of energy Energy Input Energy Output Matter Input Matter Output

14. Aspects of Starting Knowledge Characteristics from levels Level 1: Enablers that actors need to achieve their goals (include materials, energy forms, and conditions) Level 2: Gas-gas and solid-solid cycles; macroscopic energy forms (light, heat, motion) Level 3: Atoms, molecules, chemical change, cellular processes, etc

15. Using Starting Knowledge to Set Goals

16. Tools for Reasoning: Principles • Principles: • Conservation of Matter (Atoms, Mass) • Conservation of Energy • Energy Degradation • Hierarchy of Scales

17. Tools for Principles: Matter, Energy, & Scale Process Tool
