Pulleys and Gears

Learn and lift!


In this activity, groups of 4-5 students will collaboratively design, build, test and modify a series of 3D printed elevator shafts that are able to lift and move a load a set vertical distance.

Duration: 2-3 40-minute sessions

Difficulty Level: Intermediate

Group or Individual: Group

Learning Goals:

By the end of the lesson groups will:

  • Explore how pulleys/gears change speed, direction, motion and force exerted on objects
  • Work collaboratively to critically and creatively solve the design problem
  • Conceptually imagine and create a design meeting specifications and constraints
  • Communicate using scientific vocabulary when conferencing in small/large groups
  • Utilize mathematical calculations accurately to build a 3D printed concept
  • Apply scientific principles of hypothesis, experimentation, analysis and repetition
  • Devise a simple mechanism that is able to perform a predetermined function


  • 3D Printer filament for printing (and scheduled time on the printer)
  • scrap cardboard for initial prototypes
  • rubber bands
  • string/twine
  • straws
  • water bottle caps
  • hot glue gun/gluesticks
  • 3D printer such as the Cubicon Single+
  • licensed CAD software such as Fusion 360, Inventor, TinkerCAD or SolidWorks
  • computer and mouse for each student or group for CAD design

Prerequisite Skills

  • Familiarity with TinkerCAD or other 3D printing software
