K-2 lesson on energy. Substance model taught by design - author defends it explicitly: there is no way of defining energy beyond recognizing it as heat, light, electricity, or motion. Battery as bottle of water, heat moves, light flows, energy travels downhill. Foundation 0%, gap 97.4%, 18 map errors (16 REI-substance + 2 AEC).

Foundation Errors: 18 errors found across 37 student-facing passages (48.6% map error rate). Gap error: 97.4%. This is a substance-model lesson by design - the author explicitly argues for treating energy as a substance, and the lesson installs the misconception across heat, light, electricity, and motion.
A child who completes this lesson learns to say heat energy is moving into the ice causing it to melt, the battery stores power like a bottle stores water, and energy travels downhill from greater to lesser. They also learn that there is no way of defining energy beyond recognizing it as heat, light, electricity, or motion - the author’s own definition, given as a teaching commitment.
The lesson is structured in three parts across 12 pages. Part 1 (Forms of Energy) uses an energy/action card-matching game to teach four forms of energy: heat, light, electricity, and movement. Part 2 (Energy Conversion) walks through examples of energy changing form with the conservation rule that energy remains energy, matter remains matter. Part 3 (How Does Energy Travel?) describes heat radiating/conducting/convecting, light flowing from sources, electricity conducting through wires, and movement energy traveling as waves. The lesson concludes that energy always travels in a downhill direction from greater to lesser.
In short, there is no way of defining or understanding energy beyond recognizing it as heat, light, electricity, or motion and that one or another of these are needed to make things go/work/move/change. (Methods notes, p. 6)
The author’s explicit design statement that substance framing is the intended conceptual target.
Batteries described via substance analogy: electricity "flows out of the battery" like water from a bottle. When the power is gone, the battery "is empty, or dead." Substance-model framing. (Part 1, p. 5)
Explicit substance analogy: electrical power as water in a bottle.
Heat energy from the surrounding water or air is moving into the ice causing it to melt. (Part 1, p. 5)
Heat as a substance that moves between objects.
The only rational explanation is that light flows from the lamp into the room. When the lamp is turned off, the room is left dark as the light flows on. (Part 3, p. 10)
Light as a substance that flows.
Energy is observed to always travel in a downhill direction from greater to lesser. (Part 3, p. 11)
Energy as a thing that physically travels downhill.
Practices: 57.1% (amber tier). Two PRESENT, four PARTIAL, one ABSENT. The lesson is heavily Q&A and discussion-based. Models are presented rather than developed by students. Investigations are mostly demonstrations. Argument is teacher-driven correction. Mathematics is ABSENT. The activities themselves are pedagogically clean - but they are vehicles for installing the substance framing.
The substance framing is structural. The architecture commits to energy = heat + light + electricity + motion and to energy travels, is stored, is released across all three parts. Removing the substance framing would require rebuilding the lesson around the atomic-molecular picture: heat as molecular motion, light as something atoms give off, electricity as electron flow, energy as a measurement of change. This is not a passage-level fix.
| Total Passages Scored | 42 |
| Raw Gap Error | 97.4% (38 of 39 mechanism passages FALSE) FALSE = atoms/molecules not present before students are asked to explain. The student is navigating without a starting point. |
| Adjusted Gap Error | 97.4% (38 UNSCAFFOLDED FALSE; 0 scaffold) UNSCAFFOLDED = no atomic grounding at all. LESSON_ATOMS = atoms mentioned elsewhere in lesson but not connected to this concept. |
| Substance-Model Errors (REI) | 16 Curriculum treats a process or outcome as a substance - "heat flows," "energy is stored," "electricity flows like water." Student builds a substance ontology. |
| Label-as-Explanation (LAE) | 0 Curriculum provides a name and treats it as an explanation - "this happens because of gravity." Student believes knowing the name IS understanding the concept. |
| Vague-Entity Errors (AEC) | 2 Curriculum uses vague entities ("tiny particles," "building blocks") without specifying atoms or molecules. Student invents their own model with macroscopic properties. |
| Factual Science Errors (FSE) | 0 Statements that are scientifically incorrect - not imprecise framing, but wrong. Any confirmed FSE = Not Recommended. |
| Practices | 57.1% - Mid Seven practices scored PRESENT, PARTIAL, or ABSENT and averaged: asking questions, developing and using models, planning and carrying out investigations, analyzing and interpreting data, using mathematics, constructing explanations and designing solutions, and argument from evidence. Higher is better, the opposite direction from gap and map errors. Reported but not part of the Foundation Score or the verdict. |
BFSU Vol I Lesson C-1 teaches energy as a substance by design. The author identifies the substance model as a pedagogical target and defends it explicitly. Four MISCONCEPTION_BY_DESIGN flags were extracted from the teaching notes.
The lesson is pedagogically careful within its substance-model framework: it anticipates common misconceptions, addresses safety, and walks through three modes of heat transfer with correct vocabulary. The single atomic reference (atoms conserved in combustion) is correct as far as it goes.
Shallow by design - The author defends the substance framing in three explicit design statements: (1) We substitute movement energy in place of mechanical energy... energy is inherent in moving things. (2) Chemical energy is treated as one of the many forms of stored energy. (3) There is no way of defining or understanding energy beyond recognizing it as heat, light, electricity, or motion. Four MISCONCEPTION_BY_DESIGN flags were extracted. The substance framing is the pedagogical target, not an unintended consequence.
