Science / Hauora • Years 5-8 • Body systems
Use this handout to help ākonga trace the journey of kai through the body, explain what each organ does, and connect digestion to energy, growth, and hauora without reducing the topic to food rules or shame.
This page is print-ready now. If you want the examples rewritten around your health unit, school garden, hāngi science, or a junior/senior reading level, Te Wānanga can adapt the content without losing the enquiry structure.
If the lesson mentions a diagram, response planner, or explanation scaffold, those materials already exist here.
Use the companion page to connect this handout to body-systems science, explanation writing, and hauora-aware teaching in Aotearoa classrooms.
Kai is part of hauora, identity, and whānau life in Aotearoa. Teaching digestion well means showing students how the body uses food, while also keeping the classroom respectful of different food traditions, access realities, and relationships with eating.
Mātauranga Māori adds depth when you discuss kai as something linked to people, whenua, and wellbeing. The science focus here is on body function, but it sits naturally alongside Te Whare Tapa Whā and wider ideas of hauora.
Digestion begins in the mouth, where teeth break food into smaller pieces and saliva starts chemical digestion. Food then travels down the oesophagus into the stomach. In the stomach, food is churned and mixed with acid and enzymes so it can be broken down further.
From there, the partly digested food moves into the small intestine. This is where most nutrients pass through the walls of the intestine into the bloodstream. The liver and pancreas help by making substances that support digestion. The large intestine then absorbs water and prepares the remaining waste to leave the body.
The digestive system does not work alone. Once nutrients enter the blood, other body systems move them where they are needed for energy, repair, growth, and keeping us alive.
| Organ | What happens here? | Why is that important? |
|---|---|---|
| Mouth | Food is chewed and mixed with saliva. | |
| Stomach | Food is churned and broken down with acid. | |
| Small intestine | Nutrients move into the bloodstream. | |
| Liver or pancreas | Helps digestion with important chemicals. | |
| Large intestine | Water is absorbed and waste is formed. |
Choose one meal or snack. Explain how the body turns it from kai into something useful for movement, growth, or repair.
Sketch the digestive pathway from mouth to large intestine. Label the major organs and add one note beside at least three of them explaining the job done there.
Use arrows and labels only. Say each organ job aloud with a partner before writing.
Complete the table and write one clear paragraph explaining how nutrients reach the blood.
Explain how the digestive, circulatory, and muscular systems work together after a student eats lunch and then plays sport.
Level 3–4: Investigate social, cultural, environmental, and economic questions; gather and evaluate evidence from diverse sources; communicate findings and reasoning clearly for different audiences and purposes.
Level 3–4: Read, interpret, and evaluate information texts; write clearly and purposefully for specific audiences; apply critical thinking skills to evaluate sources and construct well-reasoned responses.
This resource sits within a kaupapa that recognises mātauranga Māori as a living knowledge system with its own frameworks, values, and ways of understanding the world. The New Zealand Curriculum calls for learning that reflects the bicultural partnership of Te Tiriti o Waitangi, which means every subject area has an obligation to engage authentically with Māori perspectives — not as cultural decoration but as substantive contributions to how we understand our topics. The concepts of manaakitanga (care for others), kaitiakitanga (guardianship), whanaungatanga (relationship and belonging), and tino rangatiratanga (self-determination) provide a values framework applicable across all learning areas, and all are relevant to the work in this handout.
This handout is designed to be used alongside the broader unit resources available at Te Kete Ako handouts library. Related resources from the same unit are linked in the unit planner. All resources are provided — no additional preparation is required to use this handout in your classroom.
