Project ZOOM: Rubber Band Cars

Project ZOOM - 1

PROJECT:

Due to a 70% chance of rain our 4/3 Project SOAR (Aerodynamics – Kite Flying) kickoff quickly morphed into Project ZOOM (Mechanics + Aerodynamics – Rubber Band Cars)!

STEAM Makers didn’t miss a beat moving into the DREAM LAB to aim high on designs (most wanted a “Lambo” aka Lamborghini, Porsche or Slingshot), engage in lots of shop talk and race finished models!


MATERIALS:

  • 1 – cardboard tube
  • 2 – wood dowels
  • 4 – recycled CDs
  • 4 – 1″ x 3/4″ wooden craft spools
  • 2 – drinking straws
  • 4 – large buttons
  • 10 – medium rubber bands
  • 1 – paper clip
  • Cool to have – decorative tape (for racing stripes), paint, stickers and glitter!
  • Instructors – a hot glue gun, pair of scissors and hole puncher

CONCEPTS EXPLORED:

  • Aerodynamics
  • Design Concepts
  • Prototype Development
  • Engineering – Design Assembly
  • Design Enhancements
  • Performance Analysis

FINAL ANALYSIS:

All good designs require analysis and improvement to become GREAT. While we enjoyed the development process and loved the design “look”, we’re not convinced the model holds-up well on the performance side.


STEAM MAKER CHALLENGE:

What design modifications and enhancements could be made to improve car endurance and performance?
