Domino effect (Montreal)

The giant machine for the small ball

Create a path for balls using simple but ingenious machines (the inclined plan, lever, pulley, winch, and wedge) to produce an amazing domino effect: young scientists will rise to the challenge by assembling ten platforms of a large wooden machine. Understanding a complex physical phenomenon becomes child’s play!

Objectives at the elementary level:

  • Describe the use of simple machines.
  • Recognize simple machines (lever, inclined plane, screw, pulley, winch and wheel) used in daily life.
  • Identify the necessary elements to assemble the machine.
  • Properly install simple machines (lever, inclined plane, screw, pulley, winch and wheel).
  • Describe energy transformations from one of its form into another (e.g. potential energy into kinetic energy).

Our needs

  • A space of approximately 5 metres is needed to assemble the structure at the end of the class.
  • Five teams must be created before the animator arrives.

Additional charges

  • Travel costs (minimum $ 25) based on distance apply.
  • In 60-minute workshops, if there are more than 5 groups on schedule, the workshops will be spread over more than one day and the transportation costs will have to be adjusted accordingly.
  • Additional fees will be charged if there is a delay of more than 90 minutes between two workshops.



Date (Please provide at least 2 dates, and if you have any restrictions for certain days of the week.)

Schedule (Please provide the full schedule of your school classes and if you prefer morning or afternoon. Note that a minimum of 5 minutes is required between workshops.)*
