🌿 Your Garden is a Science Lab!
A garden is full of science! When you grow plants, you're learning about biology, chemistry, and ecology. Let's explore the amazing science that makes gardens grow.

What Do Plants Need to Grow?
☀️ Sunlight
Plants use light energy to make food through photosynthesis.
- Most veges need 6+ hours of sun
- Some plants prefer shade
💧 Water
Water travels up through roots and brings nutrients to leaves.
- Too little = wilting
- Too much = root rot
🌍 Soil
Soil provides nutrients and anchors roots.
- Healthy soil has worms, microbes
- Different plants like different soils
💨 Air (CO₂)
Plants breathe in carbon dioxide for photosynthesis.
- They breathe out oxygen — for us!
- Good air circulation prevents disease
🔬 The Magic of Photosynthesis
How Plants Make Food
Photosynthesis is how plants turn sunlight into food!
Formula:
Sunlight + Water + Carbon Dioxide → Glucose (sugar) + Oxygen
This happens in the chloroplasts in leaves. Chlorophyll (the green pigment) captures the light.
Label the Photosynthesis Diagram
Draw a plant and label: sunlight, CO₂ entering leaves, water coming up roots, oxygen leaving, sugar stored
🪱 Soil Science
What's in Healthy Soil?
- Minerals — broken down rock (sand, silt, clay)
- Organic matter — decomposed plants and animals
- Living organisms — worms, bacteria, fungi
- Air pockets — roots need to breathe
- Water — held around soil particles
🧪 Experiment: Soil Jar Test
- Put 2 cups of garden soil in a clear jar
- Add water until nearly full
- Shake well, then let it sit for 24 hours
- Watch layers form: sand (bottom), silt (middle), clay (top), organic matter (floating)
What type of soil do you have?
🐝 The Garden Ecosystem
Everything is Connected
A garden is an ecosystem — all the living things depend on each other:
- 🐝 Bees pollinate flowers → fruit grows
- 🪱 Worms break down dead leaves → nutrients for soil
- 🐞 Ladybugs eat aphids → protect plants
- 🦅 Birds eat caterpillars → pest control
- 🍄 Fungi share nutrients between plants underground
🌿 Traditional Māori Gardening
Māra Kai — Food Gardens
Māori were expert gardeners who brought kūmara from Polynesia and developed techniques for NZ's colder climate:
- Raised beds — to warm soil faster
- Gravel mulch — dark stones absorb heat
- Companion planting — growing plants together that help each other
- Maramataka — planting by the moon phases

Aronga Mātauranga Māori
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.

📋 Teacher Planning Snapshot
Ngā Whāinga Ako — Learning Intentions
Students will engage with this resource to build pāngarau (mathematical) understanding — developing number sense, pattern recognition, and mathematical reasoning through hands-on, culturally grounded activities that connect to tamariki's world.
Ngā Paearu Angitū — Success Criteria
- ✅ Students can explain their mathematical thinking using words, objects, drawings, or symbols.
- ✅ Students can apply the number or pattern concept in this resource to a real or everyday context.
Differentiation & Inclusion
Scaffold support: Use concrete materials (blocks, counters, fingers) for entry-level engagement before progressing to abstract representations. Offer extension challenges asking students to generalise a pattern, write their own word problem, or explain their strategy to a partner.
ELL / ESOL: Mathematical language is a discipline-specific barrier — pre-teach key terms (e.g., equals, more than, fewer, pattern, factor) using visual representations. Allow students to demonstrate mathematical understanding non-verbally or through drawing. Pair with a bilingual buddy where possible.
Inclusion: Embed choice in how students engage — oral, written, or diagrammatic responses are all valid. Neurodiverse learners benefit from short, chunked task sequences with immediate feedback loops. Avoid timed drills in favour of exploratory tasks that reward curiosity. Make the maths classroom a safe place to be wrong and try again.
Mātauranga Māori lens: Pāngarau is a living tradition in Te Ao Māori — from the geometric precision of tukutuku and kōwhaiwhai patterns to the navigational mathematics of waka hourua, and the seasonal calculations embedded in maramataka. Framing early number sense within these contexts shows tamariki that mathematics is a human, culturally rich endeavour — not a foreign import. Encourage students to see counting, measuring, and patterning as acts of knowing their world.
Prior knowledge: Designed for early learners. No prior formal mathematics knowledge required. Teachers should assess current number knowledge before selecting appropriate entry points.
Curriculum alignment
- Number and Algebra — Number Strategies: Use a range of counting, grouping, and equal-sharing strategies with whole numbers and fractions.
- Number and Algebra — Patterns and Relationships: Generalise that the next counting number gives the result of adding one object to a set and that counting the number of objects in a set tells how many.
