CONVERSEMOS:
La primera colina de una montaña rusa siempre es la más alta. ¿Por qué no pueden ser más altas la segunda o la tercera colina (que la primera)?
CONVERSEMOS:
¿Por qué crees que la canica sube la colina baja pero no alcanza a subir la colina alta?
¿Cuánto tiempo tienes?
La siguiente actividad de la montaña rusa chocona dura aproximadamente una hora.
Si no tienes suficiente tiempo, quizás tengas que hacer esta actividad en tu próxima lección de ciencias.
If you need a natural stopping point!
Mensaje para los maestros y las maestras: Teachers: If you are short on time, this is a good stopping point. We recommend leaving your students' tracks set up so they can get right to experimenting at the start of the next session.

Box
Any box measuring 20 cm (or 8”) high will work. The most important thing is to have enough space for the track and the students to work.
A stack of books will also work. You can even use empty space on the wall to attach the roller coaster, as long as the track sits at 20 cm (8” high).

NOTE: If you want to make Bumper Coasters with foam tubing, you can view the previous version of this lesson.
We suggest students work in the same groups of four from Lesson 2. Homeschool students can work on their own, but will need to build all roller coaster tracks and hills.
Each roller coaster with hills extends about 1.2 meters (a little over 4 feet) from the box, stack of books, wall, or other surface that it’s attached to. Each group of four students will need this amount of space to work through the activity. If you don’t have enough floor space, a few student desks pushed together with a stack of books on top should work.
The entire lesson with the activity will take about an hour. There is a natural stopping point after students finish building their roller coaster tracks and before they start experimenting. If you are pressed for time or have a short class period, we recommend splitting this lesson into two sessions.
Cut enough stickers so that you have two for each group of four students that will build a roller coaster. The stickers need to be no wider than 2 centimeters so that they can fit and adhere to the roller coaster track.
Experimenting with marbles is fun, but it can also be distracting! We recommend waiting to distribute the marbles and worksheets until after students have finished building their tracks and hills.
