CONVERSEMOS:
¿Por qué parecía que tu mano tenía un hoyo? ¿Tienes alguna idea?
Pista…
Intenta el experimento de nuevo. Esta vez, averigua lo que ve cada ojo. Cierra un ojo y mantén el otro abierto.
EXPERIMENTO RAPIDO (PARTE 1 DE 4)
Maestro o maestra: Escoja a un estudiante para que él o ella lea estas palabras en voz alta.
EXPERIMENTO RAPIDO (PARTE 2 DE 4)
Maestro o maestra: Haga que el mismo estudiante diga el COLOR de cada palabra en voz alta. ¿De qué se dan cuenta?
EXPERIMENTO RAPIDO (PARTE 3 DE 4)
Ahora inténtenlo todos. Formen una pareja con otro estudiante. Escucha mientras tu compañero o compañera lee las palabras en voz alta. Después cambien de rol.
EXPERIMENTO RAPIDO (PARTE 4 DE 4)
Ahora escucha mientras tu compañero o compañera dice el COLOR de cada palabra. Asegúrate de que las digan todas bien. Después cambien de rol.
CONVERSEMOS:
¿Cuál de las dos cosas fue más difícil-- leer las palabras o decir los colores?
¿Por qué crees que fue tan difícil?
In this lesson, students explore the brain’s role in receiving information from the senses, processing that information, and controlling the muscles to enable movement. In the activity, Think Fast!, students test their reflexes with two very quick experiments and one more involved activity. They learn about how we process information in our brains and then respond to that information in different ways.

We suggest students work in pairs. Homeschool students will need a partner for the activities.
Each pair of students will need a table or desk.

In this reading, adapted from an episode of the podcast "Science Update," students learn if reading in dim light can impact your eyesight.
Catch a dollar bill
Try the “Think Fast” activity again -- but instead of a ruler, use a dollar bill. Start with the catcher’s thumb and finger in the middle of the bill. Remind the catcher that they can’t move until they SEE the bill drop.
The typical human reaction time is about ¼ second. That’s long enough for the 6-inch bill to fall completely through the catcher's fingers!
