Lesson Objectives

  • Consider the need for collecting some background data to form some ideas about impacts on energy consumption
  • Calculate the energy consumption of lights in the classroom
  • Extrapolate the light energy consumption for the whole school
  • Use real school data to determine peak energy consumption
  • Relate peak energy consumption to school activities

Evidence of Learning

  • Use data tables to calculate the energy consumption of lights (impact) in the classroom
  • Extrapolate by estimation and calculation the light energy consumption for the whole school
  • Identify peak energy consumption for a given school day
  • Determine the total energy consumed in one hour
  • Identify school activities that occurred during peak usage time

Example Learning Sequence

  • Discuss the need for taking a look at some background data
  • Use background data to determine the light energy consumption in a classroom
  • Extrapolate the energy consumption of lights in the whole school
  • Obtain data on the peak energy consumption occur in the school
  • What is the peak energy consumption in the school for a 5-minute interval?
  • How much energy is consumed in one hour around the peak time?
  • Can the peak of energy consumption be related to any significant activities occurring in the school?
