Aspects of Starting KnowledgeAspects 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

Using Starting Knowledge to Set GoalsUsing Starting Knowledge to Set Goals
Enablers/Inputs Actors/Systems Purpose/Products
Level 1:
Current Elementary Starting Point
Needs or enablers Abilities or powers of actors; settings for events
Achieving purpose or goals of actors
New Level 2:
Goal for Elementary
Different kinds of enablers: solids, liquids, gases, energy forms, conditions
Internal structure of actors
Material and energy products (gas-gas cycles, body structure, etc)
New Level 3:
Goal for Middle
Material inputs without all chemical identities; chemical energy
Movement of materials at multiple scales
Change matter and energy obeying conservation laws
Level 4:
Goal for High
Material inputs with chemical identities; Energy inputs
Movement of atoms in hierarchy of systems
Material products, energy products, energy degradation
