Music Machine Challenge Part 2

Invent a Rube Goldberg Music Machine. Combine the Snap the Gap MUSIC Kit with simple machines to create a wacky mechanical musical instrument.

Note: Session #5 is a continuation of the ideas your mentee came up with in session #4. In this session, your mentee will build a prototype, test it out, and make adjustments in preparation for the final showcase in session #6.


Session Details

Invention: Music Machine Challenge

Theme: Engineering Design Process

Time: 2 hrs

Goals for Music Machine Challenge Session #5

  2. Test your prototype

  3. Iterate and update your prototype

  4. Prep for Showcase

Materials:

  • Mentors will need to bring a connected device (phone, ipad, or computer) to access instructional videos.

  • Snap The Gap STEM Kit

  • Paper & Pens, Pencils, and/or Markers

  • Session #4 Sketch

    • For example: Cardboard, Tape, Scissors, Small ball (like marbles, bouncy balls, round beads, etc…), Books, Other Found objects

Quick Resources:

 

Meet Up

10 min

PAIR OFF & CATCH UP

Pick up where you left off last time. Review the sketch from session #4 together as well as the materials you have available.

 

Inspire

INSPIRE

Here are a few inspiring Chain Reaction Machines to get your creative juices flowing. What sounds to they make?

 

DISCUSS/CAREERS:

  • How do engineers and designers they make sure their projects work?  


Invent!

CHALLENGE: Invent a Rube Goldberg Music Machine. Combine the Snap the Gap MUSIC Kit with simple machines to create a wacky mechanical musical instrument.

Goals for Today’s Session:

  1. Create a prototype

  2. Test your prototype

  3. Iterate and update your prototype

  4. Prep for Showcase


1. Create your First Prototype

  • A prototype is a simple model that lets you test out your idea!

  • Use your sketch from session #4 as inspiration for your first prototype.

  • Don’t worry about getting everything right on the first try! The important thing is to just get started and experiment. Building a physical model of your idea makes it easier to share with others and collect feedback on your design.  This is a time to dig into the Bits and materials and start to bring your ideas to life.

Here are some tips and tricks you may find helpful when building your prototype. Maybe you want to try attaching materials to the knobs of the oscillator. Try combining with simple machines to change the sounds you make!

Try a plastic cup

Try a paper plate

 
 
 

2. TEST

  • Come up with criteria for success

    • How will you know if your invention works?

  • Test your prototype

    • Once prototype has been constructed, test your invention to make sure it works. How well does it do its job? Does it make the sounds you want?

    • Take notes about what works and what doesn’t. You can make changes in the next version. Keep in mind that the inventions might not work the first time; failure is part of the process.

3. REMIX

  • Now’s your chance to experiment with fixes and improvements.

    • Could adding a new Bit add important features?

    • Would craft materials make it stronger or give it a new look?

  • Test the invention again after a few improvements have been made.

    • Work with another person -  a classmate, friend, or your mentor. Ask the person you are working with what their favorite features are and what suggestions they have to make it better.

    • Use their feedback to create an even better version of your invention.

  • As your make changes to your invention, make sure you are documenting your prototypes are changing and the results (good and bad).

  • Continue to test and remix until the prototype is able to meet the criteria for success, or until the allotted time runs out.

Reflect

10 Min

DISCUSS WITH YOUR MENTEE

  • How do engineers and designers they make sure their projects work?  

  • What happens if the project doesn’t work?

  • How do they get better at the work they do?

 

Showcase Prep

10 Min

For the showcase, your mentee will present the following:

  • Invention description

  • Give it a name

  • What sounds does it make?

  • Important features - i.e. levers, ramps, sensors

  • How it works

    • What Bits and materials were used?

    • Describe how it works

  • Reflect

    • Favorite part about building the invention

    • What did you learn by building your invention?

  • Write down the answers and save them for next time!

 

Wrap Up

5 Min

STORE THE PROJECT UNTIL NEXT TIME

  • Check with your site coordinator about storing your mentee’s invention until the next session.

 

Next Steps

5 min

SUPER IMPORTANT HOMEWORK

  • The next session is the final session. Each participant will present their final invention at this time. Check with your mentee if there is anything else she would like to prep for next time.

  • If your mentee has notes and/or sketches documenting their process, make sure to bring them to the final showcase.
