Diet Imbalance & Deficiency
Explain the health consequences of an imbalanced diet including obesity (excess energy), starvation (severe energy deficit), and deficiency diseases (lack of specific nutrients, e.g. scurvy, rickets)

Teaching Table
Set out your lesson
Distinguish energy shortage from a specific nutrient deficiency without diagnosing anyone.
Ask the learner to explain one prerequisite idea before starting. If uncertain, revisit it; graph order is not learner readiness.
Check readiness rather than assuming source graph order establishes attainment.
Use general concept cards only; no learner food log, weight, body comparison or symptom checklist. Questions about a person’s health belong with a qualified professional.
Use the supplied stage cards on screen or scrap paper; adult key stays separate.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.
What this lesson covers and its limits
These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
- partial: Explain the health consequences of an imbalanced diet including obesity (excess energy), starvation (severe energy deficit), and deficiency diseases (lack of specific nutrients, e.g. scurvy, rickets)
Bounded objective: Distinguish energy shortage from a specific nutrient deficiency without diagnosing anyone. Obesity source framing is incomplete; multifactorial condition not reduced to moral choices or diagnosed here. Starvation/obesity definitions and personal risk estimates not fully assessed. Primary ODS search excerpts only; full-page 403 retained.
- partial: Defines obesity, starvation, and deficiency disease and links each to dietary imbalance
Energy shortage versus specific nutrient deficit only; obesity complexity limits full definition clause.
- partial: Identifies at least two specific deficiency diseases and the missing nutrient causing each
C/scurvy and D/rickets associations supplied as general education, not diagnosis.
- partial: Explains why the impact of poor diet can be long-term
Over-time harm mentioned, not individual prognosis or complete mechanism.
- partial: If {{name}} heard about conditions like obesity or vitamin deficiency diseases, could they explain how eating too much, too little, or the wrong mix of foods leads to those health problems?
Try offers taught-content-reasoning for the bounded objective; it does not establish every part of the source assessment. Obesity source framing is incomplete; multifactorial condition not reduced to moral choices or diagnosed here. Starvation/obesity definitions and personal risk estimates not fully assessed. Primary ODS search excerpts only; full-page 403 retained.
