Digestion & Enzymes
Describe the organs of the human digestive system and how food is physically and chemically digested, including the role of enzymes as biological catalysts

Teaching Table
Set out your lesson
Distinguish food movement, physical breakdown and enzyme action.
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 the complete organ/function cards. No tasting, body inspection or digestive experiment.
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: Describe the organs of the human digestive system and how food is physically and chemically digested, including the role of enzymes as biological catalysts
Bounded objective: Distinguish food movement, physical breakdown and enzyme action. Basic digestion only; detailed enzyme substrates, rates and full digestive anatomy not assessed. Agency source supports mechanism, not lesson efficacy.
- partial: Traces the journey of food from mouth to large intestine, naming each organ and its role
Route and selected functions described, card hidden for taught recall.
- partial: Explains what enzymes do and names where they are produced (salivary glands, stomach, small intestine)
Enzyme source cards supplied, including pancreas; catalytic detail simplified.
- partial: Distinguishes physical digestion (chewing, churning) from chemical digestion
Chewing/churning versus enzyme action compared.
- partial: If {{name}} ate a meal with you, could they describe what happens to the food step by step as it travels through the body — naming the organs it passes through and what each one does?
Try offers taught-content-recall for the bounded objective; it does not establish every part of the source assessment. Basic digestion only; detailed enzyme substrates, rates and full digestive anatomy not assessed. Agency source supports mechanism, not lesson efficacy.
