Save Garden Food

Overview

Today students connect food science with home economics by making a simple preserve from food grown in a garden and linking it to self-sustainability. They will observe how changes (like heat and keeping food sealed) help food last longer.

Learning intentions

• WALT investigate how food changes when heated and stored in a jar (such as jam-like or pickled-style preserves).
• WALT use observations and simple reasoning to explain why preserving reduces spoilage.
• WALT describe how garden foods can support self-sustainability at home (using, saving, sharing, and wasting less).

Success criteria

• I can describe what I notice before and after we make the preserve.
• I can explain, in my own words, how a preserve helps food last longer.
• I can link our garden produce to a sustainable food habit (planning, saving, using up, sharing).

Curriculum links

• Te Whāriki: Exploring the natural world—using senses, asking questions, and making meaning from observations.
• Te Whāriki: Knowledge of living things—understanding that plants and foods come from living things and have needs.
• Te Whāriki: Making sense of changes—noticing change over time and using everyday science language.
• Home economics connections: preparing and caring for food, following safe practices, and thinking about sustainability.

Lesson structure (30 minutes)

1. 4 minutes — Hook + question

• Use the introduction slides to start with a striking idea: “Why can the same food last for weeks in a jar but only days in the open?”
• Show a photo of garden produce and a jar of preserve; students quickly share what they think makes the difference.

2. 5 minutes — Teach: food change + safety

• Continue with the introduction slides to explain that heat can change food, and sealing/covering it can slow spoilage.
• Briefly model safe habits: clean hands, tie hair back, careful handling of hot water/heat (teacher does the hot part), and washing equipment.

3. 7 minutes — Make a simple preserve

• In small steps, use garden food (for example, soft fruit like berries/peaches if available, or cooked-down fruit/vegetable base; choose what is safe and achievable in 30 minutes).
• Follow the introduction slides instructions:
• Teacher manages heat (stove or hot water bath as required for the chosen recipe).
• Students help with measuring, stirring, filling jars (with supervision), and labelling jars with the date.
• Students make quick “I noticed…” observations (smell, colour change, thickness/texture).

4. 6 minutes — Observe + predict “how long”

• Students compare “before” and “after” using prompts from the introduction slides.
• Ask: “What do you think will happen if this jar is opened?” and “What does keeping it sealed do to spoilage?”

5. 4 minutes — Food-in-a-chain thinking

• Distribute Food Chains Question Cards and have students answer one question in pairs/independently (even with 1 student, they can work through one card thoughtfully).
• Link back to the preserve: “Where did our food come from, and how does preserving help people keep using it?”

6. 3 minutes — Plenary: reflect and connect to sustainability

• Return to the introduction slides for a final reflection: “This preserve helps because…”, and “One sustainable action I can do at home is…”
• Students finish with a quick verbal answer; teacher records key ideas.

Resources

• the introduction slides (hook image, safety reminders, step-by-step making, reflection prompts)
• the photosynthesis labelling worksheet is NOT used today (lesson focuses on preserving and food change)
• Food Chains Question Cards for a brief linking discussion
• Garden produce (chosen for safety and speed): e.g., soft fruit, or cooked-down fruit/vegetable base
• Clean jars with lids (same size if possible)
• Utensils: measuring cups/spoons, bowls, labels, paper towels
• Heat source set up and teacher-controlled (kettle, hotplate, or teacher-managed stove/hot-water step)
• Handwashing supplies and optional gloves
• Timer for short observation intervals
• Aprons or protective clothing

Assessment

• Observation checklist: can the student make at least two valid “notices” (before/after changes)?
• Questioning: can the student explain one reason preserves last longer (heat/keeping sealed/reducing spoilage)?
• Sustainability link: can the student name one self-sustaining behaviour connected to garden food (saving, using up, reducing waste)?

Differentiation

• Support: provide sentence starters on the board or via the introduction slides (e.g., “I noticed…”, “I think it lasts longer because…”).
• Extension: ask the student to compare two storage options (sealed vs not sealed) and predict which lasts longer and why.
• EAL: allow responses using drawings/single words first, then teacher prompts to build a full sentence.
• SEN: keep steps short and predictable; focus on sensory observations (smell/colour/thickness) rather than complex explanations.
