DISCUSS (1 of 2):
Imagine power is out for a day. How would that affect your life? (For example: What things stop working? What things do you lose the ability to do?)
DISCUSS (2 of 2):
Now imagine power is out for a week (or even a year). What are some ways this might affect your life?
DISCUSS:
Besides making things move, what else can electrical energy do? (Think about examples from the story.)
Hint...
Here’s what we came up with: A) It can be used to make things like traffic lights and lamps light up. B) It can be used to heat things like toasters and heaters. C) It can be used to cool things like air conditioners, refrigerators, and freezers.
I don't have a Mystery Pack
In your Mystery Pack Lesson Bag

4 labels per student |
Index Cards (3x5) | 1 card per student |
Batteries (3V 2032 button) | 1 battery per student |
LEDs
Each student needs at least one LED, but it's ideal to have more for additional experimentation. |

Teacher Note: If you keep the batteries in a different container after the lesson, please read this document for how to safely store them.
We suggest students work in pairs.
For each student, tear off a strip of aluminum foil that’s about 4 inches wide and as long as the roll (usually about 12 inches).
Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.
Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
