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.
