In this Mystery, students are introduced to electricity as a form of energy. In the activity, students investigate how electrical energy requires a circuit and design flashlights that can turn on and off.
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?
Besides making things move, what else can electrical energy do? (Think about examples from the story.)

Historical footage from the 1930s shows how life changed when electricity made its way to rural America. Watch the video (7:32) and talk about the differences between then and now:
Electrical lights have transformed our world, making it possible to light up the night. But sometimes there can be too much light!
This article talks about light pollution, a problem that’s making it harder and harder for us to see—and study—the night sky.
All you need are a few lemons, some pennies or copper wire, paper towels, and a nail.
This downloadable PDF from The Tech Museum of Innovation includes information on standards, vocabulary words, and ideas for extended learning. (Grades 4–8)
Your light up card works as a flashlight — it’ll let you see in the dark. But you probably want more than that in a flashlight.
Change your flashlight to make it easy to turn on and off. Watch this video for ideas if you get stuck.
