Elementary Students Conduct Their Own Lighting Audit
At Hazeldean Elementary School in Edmonton, Grade 5 students created an energy efficiency program through the Innovative Elementary Program. The students were able reduce the energy consumption and cost of lighting at their school and teach other students and teachers about energy efficiency.
“Elementary kids are often overlooked about their ability to make changes and advocate to the things that they care about,” said Grade 5 teacher James Stuart, who manages the Innovate Elementary Program at Hazeldean. This project is one of many ways students have demonstrated the impact they can have in their school community.
The first step was to learn about electricity, energy efficiency and light bulbs. Stuart along with some energy experts taught the students about different kinds of light bulbs and how much energy is used for each. They also learned about electricity, how it is produced in Alberta and the environmental impacts of the different types of production.
Next, students used their new knowledge to calculate their school’s electricity consumption by determining the types and consumption of light bulbs, and the number of each type of bulb throughout the building. From there, they monitored how many lights were on in each classroom, checking in at various times of the day to determine when classes were in session, when they were empty, and at the end of the day.
After collecting data, the students had to decide how they would present it. To make their information accessible to everyone, including the youngest students, they used made posters with photos and simple info boxes to teach their peers about the energy consumption of objects in their classroom. They included images of smart boards, desktop computers and lights with the amount of energy each consumed. The posters were distributed throughout the school.
The students also decided to create a contest for the classroom who was able to reduce their lighting energy consumption by the greatest amount. Using the information they had about each room’s energy consumption, they created a poster for each classroom showing its energy consumption. They continued to monitor the energy consumption of each classroom at random times until the end of the contest, with the winners earning hot chocolate made from the students’ self-made solar oven.
At the end of the lighting audit the Grade 5 group presented their findings during the school’s morning announcements. Over that time, they saw a reduction of 40 kWh. That is the equivalent of a 43-inch’ plasma TV running 32 hours a week for a month.
Through this project the students in Stuart’s Grade 5 classroom educated themselves, creatively engaged their school on the topic of energy efficiency, and were able to make changes in their school’s lighting electricity consumption.
“They were able to go out into the school and make a measurable difference,” said Stuart. “[There were] real reductions and it was really rewarding for the kids.”
