STRAIGHT N NARROW - sample

GOAL

Build a vehicle that will roll as far and straight as possible.


SET-UP

  • Prepare Scrimmage build materials

  • Build the Straight N Narrow structure according to the diagram

  • Each team needs a budget sheet (and a pencil)

  • Print or share Team Instructions

  • Tape measure or ruler

PROCEDURE

Part 1: Prep - 5 minutes

  • Budget: $100

  • Collect materials (DO NOT START BUILDING!)

Part 2: Build the vehicle - 30 minutes

  • Use only materials within the budget

  • Teams may use a scissors but NOT as a structural component of the vehicle

  • Teams must create a driver for the vehicle that will not rotate, spin or turn while on the ride

  • Teams may test the vehicle but points will not count until Part 3

  • When time is called, work on the vehicle must stop immediately

Part 3: Run the ramp! - 2 attempts

  • Teams may NOT adjust their vehicle in Part 3

  • A team member will hold the vehicle so that the back-most wheel(s) are aligned with the top of the ramp to start

  • They may only let go of the vehicle - no pushing - gravity-powered only

  • Let the vehicle roll as far as possible, coming to a complete stop on it’s own.

  • The facilitator will measure the inches straight out from the ramp to a point aligned with the nearest point of the vehicle.

  • The facilitator will measure the inches off the straight line to the nearest part of the vehicle

  • Teams will have 2 attempts and will take the better score of the two


SCORING

  • 1 point per inch = Inches out from the ramp - inches off the center-line


VARIATIONS TO DIFFICULTY LEVEL

  • Vary the time and/or budget

  • Vary the length or angle of the ramp

  • Include a roll of tape or hot glue
