Special Calendar Dates

Article by Can Geo Education

The Classroom Energy Diet Challenge is a 12-week national competition. Throughout these 12 weeks, there are specific holidays, UN days or special key dates that may be of interest to classrooms. We’ve listed some of these special dates below and connected them to different CEDC challenges to help you plan and participate. 


  • 11 → International Day of Women and Girls in Science 

    Science and energy conservation go hand in hand. As students are researching their renewable energy projects for the A Green Powered Canada Challenge, students can also pay attention to, and discuss, the roles women have in this sector.

  • 14 → Valentine’s Day

    Instead of creating Valentine’s Day cards for friends and family, why not create fun posters to educate others on smart mobility for the Buckle Up Challenge?

  • 15 → Family Day

    Do you celebrate Family Day where you live? If so, this is the perfect holiday to complete the Take-Home Challenge! For this challenge, students will work with their families to calculate the approximate number of items they can keep from being thrown away to reduce unnecessary waste in their home.

  • 20 → World Day of Social Justice

    There are so many great stories out there connected to the theme of social justice. Classrooms can use this day to read books or watch documentaries on the topic as a way to brainstorm how they will create their own story or comic strip for the Story Time Challenge.

  • 27 → International Polar Bear Day

    As students learn about and calculate their carbon footprints in the How Big Are Your Carbon Feet? Challenge, they can also discuss the connection between having a large carbon footprint and why animals like the polar bear are vulnerable or endangered.


  • 3 → World Wildlife Day

    This day is all about celebrating and raising awareness of the world’s biodiversity. This is a great day to talk to students about the role plants and animals play in our lives and how our actions and habits can affect wildlife. This discussion would be a good way to also introduce our Do you Really Need It? Challenge, where students look at needs and wants in their lives and choose an item they can go without for a day.

  • 8 → International Women’s Day

    The CEDC Video Challenge is all about getting students to produce a one-minute video or public service announcement about how to save energy. Why not use this special day to interview some important women in your students’ lives and produce a video of their energy tips? 

  • 17 → St. Patrick’s Day

    The What’s Old is New Again Challenge is all about getting students to use recycled materials to create art displays, models and upcycled objects, while encouraging others to be more energy efficient. Teachers can complete this challenge on this special day and make a St. Patrick’s theme display made out of recycled materials.

  • 21 → International Day of Forests

    The Get Growing Challenge is an opportunity to teach your students about photosynthesis and the role plants play in carbon capture and offsetting. As you complete this challenge, think about how forests help to clean our air.

  • 22 → World Water Day

    World Water Day is a great way for students to learn about the direct and indirect ways that water affects our lives. Students can complete the Water Works Challenge on this day. All they need to do is calculate the amount of water they use in a day and then determine how to reduce their usage.

  • 27 → Earth Hour

    Every year at 8:30 p.m. on this date, millions of people around the world join together to go one hour without power as a way to raise awareness of the environmental issues facing our planet. Students and their families can participate in this global movement (at their own local time) and also contribute to the CEDC’s One Hour No Power Challenge at the same time. Although the challenge asks you to do at least one hour without power, there’s no reason to stop there! Simply keep track of the total number of hours your students can go without power.


  • 7 → World Health Day

    Each year on this date, the World Health Organization raises awareness about a specific health issue or theme that affects people worldwide. Teachers can use this day to complete the What’s for Lunch Challenge and talk about healthy eating and how the food we eat not only impacts our health but also our carbon footprints. 

  • 22 → Earth Day

    This day is all about celebrating what our Earth gives us and taking action to protect the planet. Classrooms can complete our Community Connections Challenge by arranging or participating in a virtual or in-person event to help make your community a better place!
