Waffle Party!

Nice job Second Period :)

Manila Folder Bridge Design-Build Challange!

We will conduct our Design-Build challenge in two parts. By iterating on our effort, we will have the opportunity to better reflect on our experience and improve our designs. Please note that the constraints for the activity vary for the first and second effort!


Criteria:
Build a structure that can support as much weight as possible over a 18" gap.
(Note: we will use magazines for "weights" and our "gap" will be positioned between two tables)


Constraints:Part 1

• Materials:
• 2 "letter size" Manilla folders
• 2' of masking tape (may not use any piece longer than 6")
• Weighing:
• Magazines will be used as "weights"
• Your "score" for our competition is determined by how many magazines your structure supports!
• Magazines will be added to your structure one at a time until "failure" is achieved.
• You may place magazines anywhere on your structure as long as:
• All magazines must rest between the two vertical edges of the gap your bridge is spanning (magazines must be over the "gap").
• No magazines may touch the tables (magazines may not be piled up to "self support" themselves).
• Construction Practices:
• Only one end of your design may have a "pinned" connection to the table top (ie. taped). The other end must act as if it were on a "roller" connection (ie. laying on the table top).
• Manila folders may not be layered more than 3 layers thick at any location.
• Parallel structural members may not touch directly (they can be connected via non parallel connection members (ex. a "ladder" style design))
• Part 2
• Same as above but 3 folders and 3' of tape

Puzzle Cube Design-Build Challenge!

Puzzle Cube Criteria and Constraints
• Given 27 wood blocks, assemble a 3x3x3 puzzle cube.
• The cube must be made of 5 puzzle pieces, no more, no less.
• Each puzzle piece may be assembled from 3 to 6 wood blocks.
• You may not repeat any of the puzzle pieces in a given cube.
• Make your cube as challenging to solve as possible! (we'll have a contest!)


Deliverables

1) Possible Puzzle Pieces
• How many individual puzzle pieces are possible for 3, 4, 5 and 6 cubes?
• Draw as many as you can with a 1:1 ratio of squares to cubes on isometric graph paper.

2) 2 or More Puzzle Cube Solutions
• Use your 27 cubes and tape to model at least two possible cube solutions.
• Solutions must adhere to our Criteria and Constraints.
• Record the puzzle pieces for each of your solutions on isometric paper.
• Use the shading techniques we've learned for isometric drawings.
• Choose a solution and specify why you selected it.

3) Build Your Cube
• Use Elmer's glue to glue up the pieces of your chosen solution.
• Color each piece of your cube a distinct color using our class crayons.

4) Step By Step Instructions
• Using isometric paper, create step by step instructions that shows how to solve your cube.
• Each step must show the assembly from the previous step and how the next piece fits in with them ("x+y=z").
• Use the shading techniques we've learned for isometric drawings.

5) CAD Modelling
• Create an assembly of each of your pieces in Inventor.
• Create an assembly of your entire cube in Inventor.
• Create Multiview drawings of each of your pieces in Inventor.
• Create an explosion of your cube assembly in an Inventor Presentation (.ipn) file.
• Animate your explosoion. Make sure you sequence the movement of your pieces so that they don't overlap each other while in motion.
• Record your animation and post the video to your blog.
