Planting seeds: a simple science and literacy unit

Planting seeds gives young learners a small, living investigation they can touch, predict, measure and describe. As shoots emerge, children experience plant growth as a sequence of events rather than a picture in a book, building scientific language alongside early reading and writing skills.

A simple science and literacy unit can fit into everyday classroom routines. It needs only containers, seeds, water and a bright window, making it suitable for kindergartens, childcare centres and learning spaces without a garden. Teachers can adapt the activities for the changing seasons and conditions found across Australia.

A seed investigation begins

Invite children to examine several large seeds before planting them. Bean, sunflower and pumpkin seeds are easy to handle, while a packet of Australian native grass or wildflower seeds provides a useful comparison. Ask children to sort the seeds by size, colour, texture and shape, then record their predictions about which will sprout first.

Treat the seeds as living things with needs. Children can use drawings, photographs and simple sentences to show what they think a seed requires. Introduce words such as sprout, root, stem, leaf, moisture, sunlight and soil, allowing new vocabulary to develop through conversation rather than long definitions.

Preparing a simple planting station

Set up two or three planting options: seeds on damp paper towel, seeds pressed into cotton wool, and seeds planted in potting mix. Clean yoghurt containers are useful for the cotton-wool method and reflect the reuse habits common in many Australian homes. A larger tray is better for comparing rows of seeds.

Create a simple observation chart with columns for the date, the number of seeds planted and signs of growth. Place the chart where children can reach it without disturbing the plants. Keep the containers at child height and use labels with words and photographs so that children who are still learning to read can participate independently.

Planting and caring for seedlings

Model each step, from counting the seeds to covering them lightly and moistening the soil. A spray bottle gives children control and reduces the chance of washing small seeds out of their containers. Establish a predictable care routine, such as checking moisture after morning snack and rotating the containers towards the window.

The sunlight needs differ around the country. Perth and Darwin usually provide strong light quickly, while Melbourne can have cool, changeable spring weather and Sydney often has milder conditions. If windowsills receive little direct sun, supplement them with a classroom grow light. Children can graph how the seedlings respond to each location.

Measuring and recording growth

Once shoots appear, measure them with a ruler or non-stretch tape. Record the height in centimetres and draw each seedling as it looks. Comparing measurements helps children understand that growth is measurable and that plants do not all develop at the same rate.

Photograph the same group of plants each week and place the pictures beside the corresponding measurements. Invite children to use words such as taller, shorter, straight, curved, fragile and strong. A floor graph showing the height of each child’s plant gives the mathematics a playful and memorable context.

Building literacy through observation

Add a seed packet, library book or photograph sequence to the planting area. Children can identify the seed name, draw its outline and locate familiar words. This activity supports the Australian Curriculum Version 2.0 by connecting science knowledge with oral language, viewing and writing in the English strands.

Build a class seed journal with one page for each stage. Children can dictate captions such as “The bean cracked” or “A green leaf opened.” The teacher can scribe these sentences while children copy words, match letters to pictures or sequence events with counters. Later, combine the pages into a shared book about how the seeds changed.

Bringing in Australian contexts

Compare the classroom plants with plants found locally. Australian native species such as bottlebrush, grevillea and lemon myrtle can be discussed through photographs, leaf textures and habitat. State and territory biodiversity laws may protect native plants and restrict seed collection, so obtain nursery-grown seeds rather than taking them from parks or bushland.

Connect the investigation to familiar Australian food and gardening practices. Many families grow herbs, tomatoes or pumpkins, while others visit weekend farmers’ markets or buy fresh produce at Coles and Woolworths. Garden centres such as Bunnings and independent local nurseries are reliable places to find classroom seed packets, and farmers’ market growers can suggest locally successful varieties.

Sharing the learning journey

Compile the children’s drawings, measurements, photographs and dictated sentences into a class display. During shared reading, ask children to locate evidence for statements about their plants and identify changes that occurred over time. Their explanations reveal both scientific understanding and the vocabulary they have gained.

Send each family a labelled paper bag containing a seed, cotton wool and a simple care routine. The bag can be placed in a clear container near a window, and families can add observations to the child’s journal. At the end of the unit, the class book becomes a record of real growth, careful noticing and the words children used to make sense of it.
