Division B
Justine Cromer, Instructor
Teams construct a device on-site, from materials in their “junk box”, to solve an engineering challenge
Impound event & sign-up for start timeTeam of up to 2 studentsSafety – each student wears protective eye gear
w/sidesGoggles not impounded
Times – Build ≤ 30 minutes/Test ≤ 2 minutesEvent supervisor – measuring device and stop
watch
junk box requirementsAll materials must fit in the box w/a lidWidest outside dimensions = ≤95.0 cm (L+W+H)
EX: 30 + 30 + 32 = 92cmEquivalent to 37.4 inches
Buy or construct from scratchNot used for competition – except as a collection
container at state tournament for Ramp challengeIf box is too big, you will be ranked below teams
with the correct size
materialsAll materials must fix inside the junk box with
lid onMaterials must be unaltered and removed
from original (store) packagingMust meet requirements or be ranked below
other teams who doNo preassembly allowed
materialsPractice golf balls* ≤ 5
PlasticGolf balls* ≤ 8Tennis balls* ≤ 10Plates* ≤ 10.5 inches
Paper or StyrofoamCups* and bowls
Paper or StyrofoamStraws or hollow stir
rodsPaper /soft plastic ≤ 24
cm
Popsicle /craft sticks ~12x1 cm
Toothpicks – wood onlySpools of string, line,
thread or tape (non-metallic)
Paper ≤ 8.5x11 inch/ ≤ 20lbRubber bands ≤ #64 (1/4”)Plastic bags ≤ 1 gallonScissors (only as a tool)
*Must bring at least one
devices – scoring summaryCAT A: REGIONALSBridge – longest
Ties – height to loadTower - tallest
Ties – narrowest base
Cantilever – longestTies – shortest
length to edge of counterbalance
CAT B: STATEElevated ramp -
longestTies - tallest start
pointCatapult – furthest
Ties – shortest device heights
Bounce – furthestTies – smallest
bouncing surface
general rulesCAT A: REGIONALSEvent supervisor
specifies type ball prior to construction
Free-standing cup holds ball
Measurements taken before ball placement
Junk box cannot be used as part of device
CAT B: STATETeams decide which
type of ball(s) and how many to use
2 min to release all balls
Junk box or container for Ramp device only
Plate for Catapult or Bouncer targets
regionals - bridgeFree-standing bridge that supports cup with
ball for at least 5 secondsLongest open span in mm.Ties – height to bottom of load
regionals - towerTallest free-standing tower that supports cup
with ball for at least 5 secondsHighest to bottom of loadTies – narrowest base
regionals - cantileverLongest cantilever laid out from table edge
that supports cup and ball for at least 5 seconds
Measured distance parallel to ground Cannot use box or scissors for
counterbalanceCantilever must
touch tableTies – edge of table
to far side of balance
state – elevated rampBuild a free-standing ramp that transports
balls from a start point to collection container – no flat areas
Longest distance from “closest” successful start point and front edge of container (ramp not touching container)
Bonus pts for each ball in container
Tie – highestsuccessful startpoint
state - catapultFree- standing catapult that launches balls to hit a
target plate (on first impact)Requires a trigger – cannot touch ball once on
deviceFurthest distance from closest edge of catapult to
front plate - bonus pts for each ball to hit the plateBonus pts for
each ball to hit plate
Ties – shortestheight to catapult
state - bounceFree-standing bouncer that bounces balls to
hit a target plate (on first impact)Student drops balls onto bouncerFurthest distance from closest edge of
bouncer to front plateBonus pts for each ball
to hit the plateTies – tallest height
to center point of bouncing surface
bonus points – state onlySignificant advantage for successful hitsD x (n + 1)D = measured distancen = number of successful hitsEX – 2 balls hit = 20 x (2+1) = 60 ptsEX – 5 balls hit = 20 x (5+1) = 120 pts
Teams release the ballsChoose plastic golf (≤5), standard golf (≤8)
or tennis balls (≤10)
violationsViolations will rank teams below all others
w/out violations Includes…pre-assembly, incorrect use of
materials or tools, missing required material, not free-standing, does not meet minimum requirements, or not impounding on time
Also includes outside help once competition begins
Read carefully rules about moving targets and devices after competition begins, i.e. in between shots
