Classroom Challenge | Live Net Zero

Support your students to take climate action through the Classroom Challenge.

Win up to $2,000 for your classroom!

Educators in elementary and high school classrooms across Canada can enter one or both periods:

Fall: Sept 15–Dec 1, 2026
Spring: Jan 15–April 30, 2027

As part of the multi-week Live Net Zero Classroom Challenge, students take on one or more real-world sustainability challenges, from reducing food waste to rethinking how they get to school; from cutting classroom energy use to celebrating in low-impact ways.

Each challenge is hands-on, tailored to K-6 and 7-12 with curriculum connections, and available in English and French. Some can be completed in a single class period!

Educators must register on the portal where they will find the key details for entering.

In each challenge period (Fall or Spring), classes select from 21 activities and submit what they’ve done to show the impact they’ve made and share their progress. Along the way, they’re eligible for cash prizes!

Homeschoolers, extracurricular groups and clubs, First Nations and charter schools are all eligible as long as there are at least three students who are monitored by the same educator.

“You don’t need to be a climate expert to take part. The Classroom Challenge gives teachers ready-to-use materials, supports all kinds of classrooms, and helps students connect learning to real-world action.”

– Eric Nadeau, Education Program Coordinator, Canadian Geographic Education

“Thank you so much for organizing this! We’ve tackled the “Design an Environmentally Friendly Home” challenge, and our Grade 4 students absolutely loved it. I was genuinely blown away by their creativity and thoughtful ideas. Many students were so engaged that they chose to continue working on their designs at home!

I truly appreciate the opportunity you’ve given our class to participate in such a well-structured and meaningful activity. It aligns beautifully with the new Alberta science curriculum and has sparked a lot of enthusiasm in our classroom.”

21 ready-to-use activities

Activities are grouped by key themes with supporting teacher resources – and some can be completed in as little as one class period!
