The Challenge Circle Criteria Update – Synopsis
(Updated March 5th, 2018)

One of the criteria required at the time of response submittal for the Challenge Circle is that all respondents submit a synopsis of their project.

The purpose of the synopsis is to gather information from participants that will allow us to compile and make public commonalities and best practices that emerge to help guide successive Challenge Circles and the ongoing effort facing educators to integrate and take full advantage of the opportunity presented by 3D printing technology in the classroom.

Below is a short list of information we ask that you provide us.

  • School:
  • Your Name:
  • Your position within the school:
  • What subjects do you teach:
  • Number of students involved in the project:
  • Age group of the Students:

  • Please describe how you approached the introduction of the Challenge Circle (for example, was it approached as an extra-curricular activity, was it made part of an ongoing class, etc…):

  • Please describe the initial reaction of the students involved (was the project easy to understand, did the students appreciate the project on its merits, etc…):

  • Please describe how the students approached the project content (did the students plan research, what source materials did they reference, etc…)

  • Please describe how the students organized in order to resolve the project (did a group leader emerge, did the students choose to assign tasks to different people, etc…)

  • Please describe your role throughout the project:

Below are some of the questions we have been asked about the Challenge Circle


QUESTION 1 – In Challenge 2 for Grades 7-9, can the students use an alternative to the mousetrap like a Sphero?

Answer:  Alternatives to the mousetrap will be considered, but one of the core discovery points of the Challenge revolves around the conversion of kinetic energy into motion.  The Sphero presents an automated mechanical form of locomotion and so is not acceptable as a replacement.  Possible alternatives might include an elastic or balloon, but we urge communication with us prior to implementation.


QUESTION 2 – Do you need a 3D printer to take part in the Challenge Circle?

Answer:  No.  There is no requirement on the part of the Challenge Circle for participants to own or purchase a 3D printer.  The engagement involved in working with students to answer a challenge and then design their answer does not require a printer.  However there are benefits of being able to design and test print designs, and educators may find a benefit to having printer access.


QUESTION 3 – When will the submission requirements/parameters be made available?

Answer:  The submission requirements/parameters will be made available on or before the 19th of February.  A addendum to the Focus on Education Newsletter will be circulated.





Grades 1-6

Design and print a reusable stamp with your school logo.

Parameters: Special attention should be paid to making the stamp accessible and usable by all, reusable and if necessary, easy to clean.

Suggested educational value: here is a non-exclusive list of values this project offers.  

  • Digital design – Project based aspect of the challenge focuses on the basics of digital design and software using a pre-existing school logo, but also of a finger/hand handle that can accommodate all users

  • Science – different materials will suit the purpose of a stamp, and the handle.  There are also different types of ink, and solvents to clean them with. 

  • History/Social SciencesThe illustrative aspect tilts not only to the technical aspects of the stamp, but can also hint at how people communicated ideas prior the stamp and it’s subsequent evolution.

PLEASE NOTE:  if your school does not have a logo, with permission from your school please feel free to design your own.


Grades 7-9

Design and print a mousetrap vehicle (racer). As many components – body, axle, wheels – as possible should be 3D printed

Parameters: This project requires the use (or design if possible) of a ‘snap-trap’ mousetrap.

Suggested educational value:  here is a non-exclusive list of values this project offers

  • Design – development of basic design principles to devise the racer.

  • Physics – this project revolves around the explanation and conversion of the latent kinetic energy available in a ‘snap trap’ mousetrap.

  • Physics(2) – materials used in the various aspects of the design can affect the end result.  Coefficient of friction, elasticity, and mass are all aspects impacted by design and materials.

  • History – the evolution of simple machines can be touched on during this exercise.

  • Collaboration – while it’s possible for one person to design a mousetrap race, there are a fair number of considerations to this project that can lend better to teamwork.

  • Creativity – the canvas for the creation of this vehicle is wide open.

PLEASE NOTE: While the most common vehicle designed using a ‘snap trap’ is a car or wheeled racer, the vehicle does not need to be either and consideration will be given to alternative forms.   The Challenge Circle only requires a printable file (.stl) to be submitted. Video or picture files of a functional model included with the project synopsis are recommended.


Grades 10-12

Design and print the body (and other components) of a drone capable of carrying the equivalent of a ‘C’-type battery if a solid (50mm x 25mm x25 – @2″ x 1″ x 1″), or 30 millilitres (equivalent to 6 teaspoons of sugar or flour) if a liquid or granular substance.

Parameters:  As much of the drone should be 3D printable as possible. 

Suggested educational value: here is a non-exclusive list of values this project offers

  • Industrial Design – development of more sophisticated design principles are required for airborne vehicles.

  • Computer Science – programming a working drone to do what is necessary.

  • Physics (1)- a number of more advanced principles are involved in this project including but not limited to the theory of flight, conductivity, materials and mass.

  • Physics (2) – conductivity and remote control radio frequency.

  • Physics (3) – materials and mass.

  • Chemistry – battery chemistry and storage.

  • History – the evolution of flight.

  • Social Sciences – the impact of flight on the global society since the early 1900’s and the growing use of drones today and into the future.

  • Collaboration – there are a huge number of considerations in this project that require effective use of team strengths to accomplish.

  • Creativity – the canvas for the creation of this vehicle is wide open.

PLEASE NOTE: The Challenge Circle only requires a printable file (.stl) to be submitted.   Video or picture files of a functional model included with the project synopsis are recommended.
