## Activity Introduction

Quick summary: Students observe and collect data explain how energy is consumed in their classroom. They explore how the classroom temperature is affected by appliances and the weather outside. Students look at what options they have for controlling the classroom temperature.

Key lessons and understandings of activity:

• There are multiple types of renewable energy that we could use instead of coal.

## Teacher preparation

Energy audit – a day in the life of our classroom

Make a master table or use the sample table in the student worksheet with all the equipment that uses electricity or gas in the classroom. This table will be used to collate all the information after the data has been collected.

During a normal day record how long each item is:
1.    Turned on and being used
2.   Turned on and not being used
3.   Turned off
4.    On standby

For each individual piece of equipment, make a table that will help to calculate a cumulative total time each item is being used. Divide the task of collecting data between all the students.

When making the table for each item, decide if data will be collected every 15 or 30 minutes.

Once all the data has been collected, complete the calculation so they can be placed into the master table. The teacher will have to calculate averages when there are multiple items of equipment such as computers. The teacher may wish to demonstrate and ge
