CONVERSEMOS:

Cuando acomodas una ficha de dominó, pones parte de cada dominó arriba. ¿Se te ocurre otra situación en la que poner algo "más arriba" hace que algo especial suceda?

Pista…

Video trouble?

CONVERSEMOS (1 de 2):

¿Acaso una ficha de dominó puede derribar una que es un poco más grande?

Haz la prueba tú mismo si puedes. Puedes usar libros si no tienes fichas de dominó. O ve a la siguiente página para ver un video en el que nosotros lo intentamos.

ESTO FUE LO QUE SUCEDIÓ:

¡Sí funcionó! Una ficha de dominó tiene la suficiente energía para derribar a una que es un poco más grande. Ahora ve a la siguiente página.

CONVERSEMOS (2 de 2):

Desafío: ¿Crees que sería posible derribar algo MUY grande (por ejemplo, una ficha de dominó del tamaño de un edificio) usando solo fichas de dominó pequeñas?

Haz un dibujo de tu idea.

Video trouble?

CONVERSEMOS:

En términos de energía, ¿por qué es posible usar algo del tamaño de un ladrillo para derribar algo del tamaño de una casa pequeña?

¿Lo puedes explicar? Si quieres, puedes hacer un dibujo.

Piensa en esto: ¿En dónde está la energía almacenada? ¿De dónde viene la energía almacenada?

CONVERSEMOS:

¿Por qué crees que los científicos y las científicas dicen que la caída de muchas fichas de dominó es una reacción en cadena?

Featured Reviews

“My class of special needs students really worked together to fold and tape the project. They liked adding on to their chain reactors after they mastered the levers. ”
· · Teacher
“So hands-on, the kids had a blast and truly were able to answer the question with specifics and vocabulary at the end. ”
· Alison · Teacher
“The students loved the chain reaction machines and are looking forward to adding to their creations. Thank you, Doug (and team) for making science fun for students and easy for teachers to teach.”
· · Teacher
“My students loved the video of the chain reaction machine! All the videos and kid friendly explanations make science fun for my kids. Thank goodness for Mystery Science!”
· Kristine · Teacher
“The videos were really engaging for my kids. It got them thinking about how they can create their own chain reactions. We pulled out the dominoes and they're working on some projects as I type!”
· Jessica · Homeschooler
“The kids LOVED this one. They all wanted to build a domino wall to knock down! They had a lot of fun learning about the transfer of energy and building their own chain reaction. ”
· Lindsay · Teacher
“My students were captivated by the process and made excellent connections to potential and kinetic energy. Also, the step-by-step directions provided much needed practice in following a procedure. ”
· Rebekah · Teacher
“Kids loved the flexibility of creating their own chain reaction machine. The videos were inspiring!”
· Brend · Teacher
“The hands on activities!! Wonderful support so we can reach our standards and challenge all learners!!”

Activity Prep

Print Prep
In this lesson, students construct an explanation of how energy is stored, released, and transferred in chain reactions, such as falling dominoes. In the activity, Build a Chain Reaction (Part I), students are presented with an engineering design challenge to create their own chain reaction machine--a project they will continue in Lesson 5. Students experiment with a “Chain-Reaction Starter Kit.” This kit includes a lever and a ramp, which serve as the first two steps of a chain-reaction machine.

Prep Instructions

We suggest students work in pairs. Homeschool students can work on their own, but will need a partner to help with some steps.

Plan Ahead

We strongly recommend pairing this lesson with Lesson 5, “Can you build a chain reaction machine?” If you plan to do Lesson 5, don’t throw away the ramps that your students build in this lesson. Students will use these ramps when creating their very own chain reaction machine.

Classroom Management Tip

Marbles are very fun, but can be very distracting! We suggest waiting to distribute marbles to students until Step 17 of the activity.

Video Discussion

Video Discussion

La Macchina Botanica (The Botanical Machine) starts when a ball rolls down a ramp and ends by watering a plant. Watch the video for fun. Then watch it again, looking for places that energy is stored. Can you identify where energy is stored and how energy is transferred from one object to another.

Some questions to talk about:

  • What makes a pendulum swing?
  • Can you find any levers that aren’t horizontal?
  • Does this give you any ideas for a chain reaction you could make on a bulletin board?

Activity

Activity

If you don’t have dominoes but you want to make a long contraption that will fall down in an interesting way, you’re in luck. All you need to make a herringbone chain is popsicle or craft sticks and paper cups.

This 7-minute video from Kinetic King Tim Fort tells you everything you need to know.

Looking at the chain reactions that other people have built will give you ideas for your own chain reaction. There are many chain reactions online. Here are some of our favorites.
