Leaf Learning: Autumn Science Investigations

There is a certain magic that arrives with autumn in Brisbane’s leafy western suburbs. As March rolls into April and the humidity of summer begins to ease, the gardens, parks, and streetscapes of Kenmore Hills and Brookfield undergo a quiet but remarkable transformation. Trees begin to shift. Leaves change. And young children — with their extraordinary capacity for wonder — start asking the most spectacular questions.

Why is that leaf yellow? Why does it fall off? Where does it go? Can I keep it?

At Kenmore Hills Early Learning, these questions are not interruptions to the day. They are the day. They are the starting point for rich, meaningful, child-led science investigations — grounded in nature, guided by curiosity, and deeply connected to our Wildhood philosophy of learning through authentic outdoor experience.

This autumn, we invite you to discover how a simple leaf can become the most powerful science classroom a young child will ever step into.

Why Leaves Are the Perfect Science Tool for Young Children

A leaf is deceptively simple. It’s small enough for tiny hands to hold, free to collect, and endlessly fascinating when you really stop to look at it. But to an early childhood educator trained in inquiry-based learning, a leaf is a complete science laboratory.

Through leaf investigations, young children naturally engage in the core processes of scientific thinking:

Observation — What do you notice about this leaf? What colour is it? What does it feel like?
Comparison — How is this leaf different from that one? Which is bigger? Which is rougher?
Classification — Can you sort these leaves into groups? What’s the same about these ones?
Prediction — What do you think will happen if we leave this leaf in the sun for a week?
Investigation — Let’s find out. Let’s test it. Let’s look again.

These are not abstract academic concepts. They are the natural thinking patterns of young children who are given the time, space, and permission to wonder. As Nature Play QLD — a Queensland Government-supported organisation — confirms, opportunities for child-led investigation using loose parts from nature set the groundwork for cognitive processes and support scientific and aesthetic thinking in young children.

Autumn Leaves in Brisbane’s West: What Our Children Are Noticing

Unlike the tropical north of Queensland, the Kenmore Hills and Brookfield area sits in a subtropical climate zone that offers genuine seasonal variation. In autumn, our local environment offers children a genuinely rich palette of natural science to explore:

Deciduous trees dropping leaves along Brookfield Road and throughout local parklands
Shifts in leaf colour — from deep greens to golden yellows, rusty oranges, and rich burgundies in ornamental trees throughout the suburb
Changes in leaf texture — fresh leaves feel waxy and smooth; fallen leaves become papery, crisp, and crumbly
Seed dispersal in action — seed pods falling, splitting open, releasing seeds carried by the autumn breeze
Insect behaviour changing as temperatures cool — new visitors appear, others become less active
Morning dew settling on leaves and grass in ways it didn’t during the humidity of summer

Every one of these phenomena is an invitation to investigate. Every observation a child makes outdoors is the beginning of a scientific thought.

Leaf Learning Investigations: What We Do at Kenmore Hills Early Learning

Our educators don’t “teach” science in a formal sense. They create conditions for science to happen naturally — by setting up rich provocations, asking open-ended questions, and following children’s curiosity wherever it leads.

Here are some of the leaf-based science investigations you might find unfolding in our outdoor spaces this autumn:

🍃 The Sorting Investigation

Children collect leaves from across our outdoor garden spaces and sort them by size, shape, colour, texture, and vein pattern. This builds early mathematical thinking — classification, comparison, and data organisation — while grounding children in genuine scientific observation.

🔍 The Close-Up Investigation

Using magnifying glasses, children examine the intricate vein structures of different leaves, discovering that each leaf has its own unique pattern — like a fingerprint. This is a moment of genuine scientific awe that no worksheet could replicate.

💧 The Water Investigation

What happens when you place different leaves in water? Do some float and some sink? Do some absorb water while others repel it? Children make predictions, carry out the test, and observe the results — following the exact same process as a professional scientist.

☀️ The Sun and Shade Investigation

Children collect leaves from a sunny spot and a shaded spot in our garden and compare them — are they different colours? Different temperatures? Different textures? This is a beginning exploration of photosynthesis, told entirely through the language of play and wonder.

📰 The Pressing Investigation

Children select their favourite leaves, press them between paper and heavy books, and return to them over several days to observe what changes. Time, patience, observation, and comparison — this is science at its most patient and purposeful.

🎨 The Leaf Rubbing Investigation

Placing paper over a leaf and rubbing a crayon across it to reveal the hidden vein structure beneath combines science with art in a way that genuinely astonishes young children. Every time. Without fail.

The Science Behind the Leaves: What Educators Help Children Discover

For those who are curious — here’s the science behind autumn leaf change that our educators weave into conversations with children at a developmentally appropriate level:

Leaves are green because of a chemical called chlorophyll, which helps the leaf capture sunlight to make food for the tree. As autumn arrives and the days grow shorter, the tree gradually stops producing chlorophyll. As the green fades away, the other colours that were hidden in the leaf all along — yellows, oranges, and reds — are finally revealed.

The tree then begins to seal off the leaf, and eventually it falls — a process called abscission — which protects the tree during the cooler, drier months ahead.

You don’t need to use these words with a three-year-old. But you can say: “The leaf was always yellow inside — the green was just covering it up. When the green goes away, the yellow comes out to say hello.”

And a child’s eyes will go wide.

That is science. That is learning. That is Wildhood.

Connecting Leaf Learning to the EYLF

Every investigation we facilitate at Kenmore Hills Early Learning is grounded in the Early Years Learning Framework (EYLF) V2.0 — Australia’s national framework for early childhood education — and the Queensland Kindergarten Learning Guidelines (QKLG) which guides our kindy program.

Leaf learning is a particularly rich vehicle for EYLF outcomes:

Outcome 2 – Children are connected with and contribute to their world: Direct engagement with the natural environment — observing, touching, investigating, and caring for leaves and plants — builds children’s deep understanding of the living world and their sense of responsibility toward it.
Outcome 4 – Children are confident and involved learners: The EYLF explicitly describes children as developing “a range of skills and processes such as problem solving, inquiry, experimentation, hypothesising, researching and investigating.” Leaf science brings every one of these processes to life.
Outcome 5 – Children are effective communicators: Describing a leaf’s texture, explaining a prediction, sharing a discovery — science investigations are among the most naturally language-rich experiences in early childhood education.

As Nature Play QLD notes, playing in nature stimulates creativity and problem-solving skills integral to executive function development — the same skills that underpin success not just in school, but across a child’s entire life.

Extending the Learning: Leaf Science at Home in Kenmore Hills

The science doesn’t have to stop when your child leaves our centre. Here are some simple, joyful investigations to try together in your own garden or at local parks in the Kenmore Hills and Brookfield area this autumn:

Collect and compare — Gather ten different leaves from your garden or a local park. Sort them together. Which is the biggest? The smallest? The roughest? The most unusual shape?
Make a leaf map — Draw a simple map of your garden or street and mark where you found each type of leaf. This combines science, geography, and early literacy in a wonderfully natural way.
Observe a tree over time — Choose one tree in your garden or nearby park and photograph it every week throughout autumn. Watch how it changes. Talk about what your child notices.
Press a collection — Start a family leaf collection. Press and preserve leaves from different trees in your neighbourhood, labelling each one with where it was found.
Go on a texture walk — Walk through your local area and challenge your child to find leaves that are smooth, rough, waxy, bumpy, or furry. The Queensland Government recommends encouraging children to engage all five senses in their exploration of the natural world — and a texture walk does exactly that.
Make leaf soup — Fill a bucket or tub with water, add collected leaves, sticks, seeds, and mud from the garden, and let your child “cook.” This is science, maths, sensory play, and imagination all in one gloriously messy experience.

The Kenmore Hills Difference: Science Through Wildhood

At Kenmore Hills Early Learning, our Wildhood philosophy means that science is never a subject we “do” on a Friday afternoon. It is woven through every moment of our children’s day — in the garden, at the water trough, under the trees, in the mud.

We believe, as the Queensland Department of Education confirms, that outdoor spaces are not simply play areas — they are critical learning environments where children develop curiosity, resilience, motor skills, and a genuine love of discovery.

When a child at Kenmore Hills Early Learning kneels in the garden to examine a fallen leaf with a magnifying glass, they are not just playing. They are doing exactly what every scientist in the world does: they are looking carefully, wondering deeply, and beginning to understand how the world works.

That is a gift we are proud to give every child in our care — every single autumn, and every day in between.
