CONVERSEMOS (1 de 2):

Imagínate que no tienes luz todo un día. ¿Cómo afectaría tu vida un apagón? (Por ejemplo: ¿Qué tipo de cosas dejan de funcionar? ¿Qué cosas no puedes hacer sin luz?)

CONVERSEMOS (2 de 2):

Ahora imagínate que no tienes luz toda una semana (o un año). ¿Cómo cambiaría tu vida?

Activity Prep

Print Prep
In this lesson, students are introduced to electricity as a form of energy. In the activity, Build a Flashlight, students investigate how electrical energy requires a circuit and make their own mini flashlights from LEDs, button batteries, and strips of aluminum foil. Along the way, they’ll learn about the anatomy of a battery, begin to see how circuits work, and discover how handy an on-off switch can be.

Discussions

Discussion

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:

How did electricity change life in the home? On the farm?

How did electricity change the lives of men, women, and children?

Could you live without electricity in your house today?

Challenge: Turning Your Flashlight On and Off

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.
