Energy Used in a Day.

• What do we really mean when we say we use
  energy?
• The objective of this activity is to make
  students aware that they do not use energy but
  rather transform it into forms needed to meet
  their needs.

3
State Frameworks

• This activity is aligned with the following
  Arkansas State 7th Grade Science Content
  Standards
• PS.7.7.1- Identify natural resources used for
  energy needs
• PS.7.7.2- Describe alternatives to the use of
  fossil fuels
• PS.7.7.4- Investigate alternative energy sources

4
The Activity

• The students brainstorm basic daily activities
  and determine the external source of the energy
  and how that energy is transformed.
• Students then discuss which of these activities
  use fossil fuels as a source
• Then, students will pick appliances that they use
  regularly from a given list that provides the
  power ratings for each appliance.
• Then, students calculate the amount of energy
  they use each day and compare it to the amount
  of energy they consume (See Power of a Student
  lab)

Energy in an Electric Circuit Game

• This game demonstrates for students the following
  principles of electricity
• Direction of the flow of energy in a circuit
• Energy transferred with a conductor to a bulb
• Electrons continuously carry energy in a closed
  circuit

6
This activity is aligned with the following
Arkansas State 8th Grade Science Content
Standards

• PS.7.8.1- Construct open and closed electrical
  circuits
• PS.7.8.2- Describe and diagram open and closed
  series and parallel circuits
• PS. 7.8.3- Compare and contrast open and closed
  series circuits and parallel circuits

7
Supplies Needed

• Energy Use Handout
• Game boards for circuit game

How wed use these activities in our classes!

• Energy Used in a Day.
• To build on already presented knowledge about
  energy transformations
• To make students more aware of their energy
  footprint
• Begin discussion of alternative energy sources
• This could easily be used as either a pre-lab
  leading into further discussion or as an
  inquiry-based lesson.

How wed use these activities in our classes!

• Energy in an Electric Circuit Game
• As an introductory activity to open and closed
  circuits
• This is a pre-lab type game designed to engage
  students and get them thinking about electricity
  and how currents work.
• We have made some adaptations.
