Sustainability Activities for Primary School Classrooms
Looking for engaging sustainability activities for primary school classrooms? Teaching children about the environment doesn’t have to be complicated. Through storytelling, creative projects, outdoor exploration and everyday actions, teachers can help students understand how their choices affect the world around them.
Sustainability education encourages children to become curious about nature, think critically about environmental challenges and discover practical ways to care for our precious planet. Whether you’re planning a dedicated sustainability lesson, exploring environmental themes through English or Science, or looking for ideas for a whole-school sustainability program, these activities offer a hands-on place to start.
Inspired by Rosie Rescues Her Precious Planet, these classroom activities are designed to help primary school students explore sustainability in an engaging way.
1. Start with a sustainability story
Stories are a wonderful way to introduce environmental ideas and help children connect emotionally with the natural world.
Read Rosie Rescues Her Precious Planet together and invite students to think about the story’s characters, challenges and environmental themes.
Try these discussion questions:
What makes our planet precious?
What environmental problems can we see in our community?
How do our choices affect plants, animals and other people?
What could we do to help protect the places we love?
Invite students to draw their favourite moment from the story, to draw the characters or themselves doing a sustainability action or write one thing they would like to do to care for the planet.
2. Become waste warriors
Help students discover what happens to the things we throw away and how we can prevent waste from being created.
Introduce the waste hierarchy:
Refuse: Can we say no to something we don’t need?
Reduce: Can we use less and avoid unnecessary waste?
Reuse: Can we use something again, repair it or give it a new purpose?
Recycle: Can the material be recovered and turned into something new?
Rot: Can suitable food scraps and organic materials be composted?
Using clean packaging, picture cards or classroom examples, ask students to identify what they could do with each item before throwing it away. Discuss why preventing waste and reusing items can be preferable to recycling.
Classroom challenge: Identify one source of avoidable classroom waste and work together to find a practical alternative (such as soft plastics).

3. Go on a nature walk
Take learning outdoors and encourage students to observe the biodiversity around their school.
Give students a clipboard and ask them to look for different leaf shapes, birds, insects, seed pods, natural textures and places where small creatures might shelter.
Encourage students to observe nature mindfully without uprooting plants, picking flowers or disturbing wildlife. Teach them that every living thing has value and deserves respect, fostering a sense of care and responsibility for all flora and fauna.
After the walk, discuss:
What living things share our school grounds?
What do plants and animals need to survive?
How do trees and other plants help people and wildlife?
How could we make our school grounds more welcoming for nature?
Students could create a nature journal, draw a habitat or design a sign encouraging others to protect a local green space.
For adults or older kids, we’d recommend looking at iNaturalist which is a free, non-profit organisation. They have a citizen science app that lets everyday people record and share photos of plants, animals, fungi and flora to help track global biodiversity. It’s like playing Pokemon Go but for biodiversity!
4. Create a classroom reuse station
Before buying new craft supplies, encourage students to consider what materials are already available.
Set up a reuse station with suitable clean materials such as scrap paper, cardboard, fabric offcuts and reusable craft supplies (you could even do this for books, toys and any unwanted items).
Students can use these materials to build models, create artwork or develop prototypes for a design challenge.
Ask students to think about how an item could be used differently before it is discarded.
Creative challenge: Can you design something useful using only materials that are already available?
Encourage students to explain what they made, which materials they reused and how their design helps reduce waste.
5. Become water-saving detectives
Water is essential for people, plants and animals, making it an important topic for sustainability education.
Ask students to investigate how water is used throughout the school. With teacher guidance, they might observe drinking fountains, garden areas and handwashing facilities, identifying opportunities to avoid wasting water.
Discuss:
Why do people, plants and animals need water?
Where does the water we use come from?
What happens when water is wasted?
How can we use water thoughtfully at school and at home?
Students can create water-saving reminder signs or develop a class pledge to use water responsibly or even just reporting on.
6. Design a sustainable classroom
Invite students to imagine a classroom that cares for both people and the environment.
Working in small groups, students can draw or build a model of their ideal sustainable classroom. They might include natural light, indoor plants, clearly labelled waste stations, reusable supplies, water-saving ideas and ways to reduce unnecessary energy use.
Ask each group to explain how its design choices could help.
For an extension activity, students can select one achievable idea and trial it in their own classroom. A really great example of an amazing, sustainable classroom is the University of Melbourne Abbotsford ELC. You can read more about them here.
7. Start a compost or worm-farm
Composting helps students understand that some materials we think of as waste can become a useful resource.
If your school has a compost system, worm farm or food organics collection service, use it as a starting point for an investigation or even set up one.
Students can explore which materials are accepted, observe changes over time and learn how decomposers help break down organic matter. Discuss how suitable food scraps can be diverted from landfill and used to support healthy soil.
Investigation questions:
What happens to a food scrap over time?
Which materials belong in our school’s compost or organics system?
What do worms and other decomposers do?
How can we prevent food waste before it happens?
8. Create a biodiversity-friendly school
Help students explore how school grounds can provide habitat for local wildlife.
Depending on your school’s space and resources, students could research locally appropriate plants, investigate pollinators, design habitat signs or propose ways to protect existing vegetation.
Invite students to consider the needs of different living things when planning improvements.
Classroom challenge: Design a small biodiversity project that could make your school more welcoming for native plants and animals.
Students could present their ideas to the class, school leadership or grounds team.
9. Run a low-waste lunch challenge
Lunch provides a familiar opportunity to discuss waste prevention and everyday sustainability.
Ask students to observe the types of packaging that appear in lunchboxes, without judging individual families or comparing what students bring to eat. Discuss practical ways to avoid unnecessary waste, such as using a reusable lunchbox or drink bottle where possible.
Students can brainstorm how to reduce food waste, store food appropriately and sort packaging according to the school’s waste guidelines.
Reflection questions:
What waste could we avoid creating?
What items can be used again?
How can we prevent edible food from being wasted?
What might make low-waste choices easier for families?
Keep the challenge positive and inclusive. Families have different budgets, routines and access to reusable items, so focus on ideas rather than competition.
10. Take one planet-friendly action
Sustainability can feel overwhelming when environmental problems seem very large. Help students recognise that small actions can contribute to broader change when people work together.
Ask each student to choose one achievable action they can practise over a week. This might include using both sides of paper, caring for a classroom plant, reusing materials, saving water or helping sort waste correctly.
Invite students to record their action in a simple journal or tally chart.
At the end of the week, discuss what worked, what was challenging and which actions the class would like to continue.
Reflection prompt: “One thing I did to care for our planet was…”
The aim is not to expect children to solve environmental challenges on their own, but to help them develop the knowledge, confidence and sense of agency to participate in positive change.
How does sustainability education connect to the curriculum?
Sustainability activities can support learning across several primary curriculum areas, depending on the year level and learning intentions, and should be embedded into everything we do and in our daily actions.
English: Reading, discussion, storytelling, persuasive writing and reflection.
Science: Living things, habitats, materials, observation and scientific inquiry.
Humanities and Social Sciences: Places, communities, human-environment relationships and shared responsibility.
Design and Technologies: Designing solutions, selecting materials and evaluating ideas.
The Arts: Communicating environmental ideas through drawing, making, drama and storytelling.
Sustainability cross-curriculum priority: Exploring interconnected systems, environmental responsibility and opportunities for action.
Teachers should check the current Australian Curriculum and relevant state or sector requirements when planning specific learning sequences.
