Lesson Plan

Discover how many hours your class can go without using any power.

There is only one option for this challenge. (Please see below for suggested modification for completion at home). You will only be able to submit your work and get points for one option.

Please complete it to determine how many hours your class can go without power. Once you hit “submit,” your hours will be added to the total savings on the Classroom Energy Diet Challenge homepage.

Option 2: Suggested modification for completion at home

Students will complete a modified version of Option 1 and will attempt to go without power for a minimum of one hour at home.

Students can draw or write about their experience and what they did during their hour without power. Parents/guardians or students can take a photo of the essay or drawing and can email it to the teacher.

Hint: this challenge ties in nicely with the “Do You Really Need It?” challenge. 

Hint: teachers can use the “Tracking sheet” (found in the lesson plan) to keep track of student hours. Try your best to reach the minimum of 15 with everyone pitching in an hour! 

The teacher can submit the Tracking sheet along with any essays or drawings as proof of their classroom completing the challenge.

Learning outcomes
By the end of this activity, students:

  • will understand why reducing energy consumption is important
  • will be able to explain why and how they reduced their energy use

Update on the Classroom Energy Diet Challenge (CEDC) in response to extended school closures

We are excited to announce the continuation of the CEDC! We understand that the extended school closures impose a few difficulties when it comes to continued participation in this program, and invite classrooms to channel their creativity and ingenuity to complete any outstanding challenges. Where possible, we will be maintaining the current structure, deadlines and prizing, and will be adapting the existing challenges to be more easily completed by members of the classroom who are self-isolating. If you are able to work safely and remotely to complete challenges with your students, please continue to submit your proof!

Thank you for your patience and understanding, and stay tuned for another update in the coming days.
