CAN YOU BALANCE?GOLDBERG’S NOT-SO-SIMPLE-MACHINE
Learning Description
In this project, students will engage in the engineering design process to create a Not-So-Simple-Machine demonstrating force and motion! Students will create a drawing of a Rube Goldberg Not-So-Simple-Machine and create a kinetic sculpture, or working model, of that machine. In this project, students will demonstrate how simple machines can be combined in a complicated way to perform a simple task.

Key Vocabulary
Content Vocabulary
- Force - Any interaction that, when applied to an object, can cause it to change its motion or shape
- Balanced forces - Two or more forces acting on an object in such a way that they cancel each other out, resulting in no change in the object's motion
- Unbalanced forces - Two or more forces acting on an object are not equal in size or are not opposite in direction, causing the object to accelerate (change its speed or direction)
- Gravitational force - The force of attraction that pulls objects toward each other due to their mass
- Motion - The change in the position of an object over time
- Mass - A measure of the amount of matter in an object or substance
- Simple machines - Basic mechanical devices that make work easier by altering the direction or magnitude of a force; the building blocks for more complex machines
- Rube Goldberg - An American cartoonist, engineer, and inventor best known for creating elaborate, humorous illustrations of complex machines designed to perform simple tasks in overly complicated ways
- Inclined plane - A flat surface that is tilted at an angle
- Lever - A simple machine consisting of a rigid bar or beam that pivots around a fixed point called the fulcrum
- Wedge - A simple machine that consists of a triangular-shaped object, often with a sharp edge, which is used to split, cut, or lift objects
- Pulley - A simple machine consisting of a wheel with a groove around its edge, through which a rope, chain, or belt can pass
- Screw - A type of simple machine that consists of an inclined plane wrapped around a central shaft or core
- Wheel and axle - A simple machine that consists of two circular objects—a larger wheel and a smaller axle—that are connected and rotate together
Arts Vocabulary
- Assemblage - An artistic process in which a three-dimensional artistic composition is made from putting together found objects
- Kinetic sculpture - Three-dimensional art that is designed to move
- Craftsmanship - Skill in producing expertly finished products
- Sketch - A rough drawing, often made to help make a more finished product
- Variety - The differences in a work, achieved by using different shapes, textures, colors and values
- Two-dimensional art - Art depicted on a flat surface
- Three-dimensional art - Art that has height, width, and depth

Instructional Design
Opening/Activating Strategy
- Divide students into small groups.
- Human Simple Machines: Each group will choose a card with the name/picture of a simple machine. The group will act out the simple machine for the class to identify.
- Encourage students to think about how they can creatively use their body to work together and become the various parts of a simple machine
Have the Mousetrap Game set up and choose a group of students to demonstrate to the class how it runs. Explain to students that they will be using their creativity to design an unnecessarily complicated machine to do a simple job. Alternative: Show a video of the game being played.
Work Session
- Tell students that they will be designing a machine inspired by Rube Goldberg. It will be a complicated machine to complete a simple task.
Part I - Planning:
- Students will work in small groups to:
- Research Rube Goldberg machines.
- Brainstorm ideas for possible purposes of a machine they will create.
- Brainstorm uses for materials provided.
- Experiment with various materials.
- Decide on a goal for the machine.
- Show students a list of the materials that are available to them.
- Individually, students will sketch an initial design with pencil on copy paper. Tell students that they should include six or more individual steps, using four or more simple machines.
- Remind students that they should use as much variety as they can and try to include a "Wow!" factor.
- Students should compare their designs and choose which to build or combine ideas into one final idea.
- Students should label their sketch with the materials that they will use.
Part 2 - Creating:
- Students should work in their small groups to create their machines.
- Students should create one piece of the machine at a time and combine components as the test whether they work.
- Teacher tip: If creating takes more than one class period, at the end of class, take photos of the machines created in each group and disassemble enough to store. Machines can be stored in storage boxes.
- After the machines are finished, students should test run the machine three to four times for evaluation.
- Finally, students will sketch their final machine and label the simple machines that they used.
Classroom Tips:
Divide students into groups of three to four. Students who are having difficulty might start with the last step and work backwards. One student in each group should take pictures of building progress at the end of each class period before the machine is disassembled and stored. Each group should have a labeled box for storing partial products.
Closing Reflection
- After completing their machines, have students reflect on the following questions:
- How did you choose the job you wanted your machine to do?
- What would have been the simplest way to do the job without the machine?
- Why was it important to plan before trying to build the machine?
- How did your drawing change from your first sketch to the final copy?
- What would have made the process simpler?
Assessments
Formative
- Teacher will observe the students experimenting to determine whether they understand how simple machines work.
- Teacher will question students on the functions of their simple machines.
- Teacher will observe cooperation and participation.
- Teacher will periodically assign each group a different simple machine to act out for a neighboring group to identify.
Summative
- Final drawing of completed machine with simple machines labeled
- Working Rube Goldberg machine
- Goldberg’s Not-So-Simple-Machine Rubric
