Cube Design Challenge
Challenge: Cube Design Challenge
Overview: Create a cube with the items provided.
Kit:
50 Straws
Chenile Craft Stems (Pipe Cleaners)
Paper clips
Dowels
Paper
3 x 5 cards
Tape
Scissors
Instructions:
Introduction: Introduce the project to the group. Define a cube, and any parameters or rules.
Material Overview: (5 minutes) Groups look at their supplies, discuss methods and design but may not start building.
Building: (15 minutes)
Build a Cube
• Build a cube with 10 cm sides
• Use only straws and paperclips
• All materials should be recyclable, develop a checklist of criteria
• Design and build your model
• All angles must be within +/- 5 degrees and sides must be within +/- .5
Optional--Test for strength, how many books can it carry?
• Share with others your data, methods for use of paper clips
Testing/Reviewing/Sharing
(Optional: Redesign or modify)

Closed Network PVC Building Challenge
This challenge comes from Mark Belson Experiential Education Coordinator at Oregon State University.
Challenge: Closed Network PVC Building
Objective: To utilize all PVC pieces to construct a completely closed circuit.
Rules: You must use ALL (50) PVC pieces to build the “closed circuit” and then get approval from the facilitator before completely disassembling the PVC system.
Clue: Think of it like an ant farm, where by if you place ant into the PVC pipe and then you attach the end cap on the structure the ant will not be able to get out. Also, there are many solutions to this challenge.
Bag includes 50 PVC pieces:
End Cap=1
In line connectors=2
Four way connectors=2
45 degree connectors=2
Tee connectors=5
90 degree connectors=11
3” lengths of PVC=4
6” lengths of PVC= 10
12” lengths of PVC=8
18” lengths of PVC=5
