This year, I’ve found myself taking a deeper dive into a question that has been quietly shaping my work for some time:
What does sustainability education truly look like in a K–5 setting?
I come at this question from a unique position. I’m not a classroom teacher occasionally adding sustainability into a unit…I am the sustainability classroom. As a K–5 sustainable energy teacher, I meet every student in the school once a week. My role is to build a curriculum from the ground up, spanning everything from environmental literacy to Green Careers, while intentionally connecting ideas across all grade levels. My job is to connect the dots and fill in the spaces! To create a learning progression that grows with students year after year.
Now that I’m in my third year, I’ve moved past what many teachers know as survival mode. That phase where you’re just trying to stay afloat and make sure something meaningful reaches your students.
I’ve entered what I think of as my “why” phase.
- Why am I teaching this?
- Why do my students need to know this?
- Why does this curriculum matter?
When you reach this stage, reflection naturally leads to research, and sustainability education raises some important questions.
Sustainability Education Needs More Than Add-Ons
Too often, sustainability education exists in fragments: a mini lesson here, an extension to a science unit there, a quick mention of recycling when the moment allows.
While those efforts are valuable, sustainability education is more than isolated moments. At its core, it’s about understanding systems, processes, and actions. It’s about helping students think beyond vocabulary and toward how human choices shape the world around them.
Without a clear framework, sustainability becomes something students hear about instead of something they truly understand and apply. If we want sustainability education to lead to meaningful change, it needs intentional structure and continuity.
Moving Beyond the Three R’s
If there’s one goal I would encourage educators to set, it’s this:
Think beyond Reduce, Reuse, and Recycle.
My students know the three R’s well. But what they’re ready for now is deeper thinking, especially around Rethink and Refuse.
- Why do we consume the way we do?
- Who designed these systems?
- What choices do we have?
This shift encourages students to question habits and systems rather than simply manage waste. Sustainability isn’t just about fixing problems…it’s about preventing them and understanding the “why” behind our actions.
The Outdoor Learning Matters
With even a basic understanding of sustainability, the outdoor classroom holds incredible potential. Connecting with nature through shared language and experiences is foundational to sustainability education. When students build a relationship with the natural world, sustainability stops being abstract and starts becoming personal.
You don’t need to hug a tree, but students do need opportunities to understand why that tree matters. Getting outside, observing, wondering, and noticing patterns helps students care. And caring is what leads to change.
What Next?
As I continue this work, I’m realizing sustainability education isn’t about adding more content; it’s about creating meaningful connections and building systems of thinking that grow with our students.
I’m currently working toward developing a clear, usable framework for sustainability education that teachers can adapt and apply across elementary grade levels. Next week, I’ll be sharing a few practical tips for implementing sustainability education in an elementary setting, grounded in real classroom experience.
So, what’s next? This is just the beginning of the conversation, but it’s one worth having. And, I hope I can provide you with a little more clarity on how to get Sustainability Education practices into your classroom in a meaningful way.
