Project
You will be building a fixed bridge using only foam core, and white glue. Your goal is to build a bridge that can bear as much weight as possible. Try to achieve a balance of strength, and beauty, in the design of your bridge. During the final critique, your projects will be strength-tested. Each bridge must hold a minimum of 50 lbs. You will do your best to achieve a balance of strength, and beauty, in the design of YOUR bridge. !
Specs
Materials- You may only use the foam core provided in class. You may only use white glue (Elmer's glue). You man not use hot glue, epoxy, or tape.
Length and Span- Your bridge must be to span EXACTLY 24" (inch). The tables will be secured at exactly 24" apart. Note: The span is the part of the bridge that is not supported by anything beneath it (like the table, leg, or chair). Keep in mind that there will need to be additional length in order for the ends of the bridge to rest on the table top. Therefore, the bridge has to be longer than 24" (inches).
Width and Height- The bridge must have a minimum width of 8" (inches). We will be placing bags of clay on the TOP MIDDLE of your bridge.
Lastly, the clay needs a solid place to lay. There must be a flat area on the top of the bridge where we can stack bags of clay for the strength test. The bags are approximately 6" (inches) wide.

Rubric
You will be assessed on the strength of your bridge, craftsmanship, and it's aesthetic qualities. and name or title.
Process
1. Sincerely ask yourself the question... why build a bridge?
2. Research bridges and bridge building (bridge history).
3. Design - make plans/ drawings of "your" bridge.
Written Component
On a single page (typed), answer thesetwo questions:
1) Why do people/institutions/societies build bridges?
2) Why will you build YOUR bridge?
You must think deeper than the obvious answer, which is: to get to the other side.
Think about the bridge as a metaphor.;
What are you crossing?
How, who, or what, will cross it?
And best of all... why?
Play with this question or idea... How does the bridge fit aesthetically and conceptually into your selected ideal or place?
This one-page (200-300 words) paper will be due april 7th.
Your paper must be printed out, and clearly labeled with your name, date, and the title of your bridge. In addition, it must include the scale of your bridge- Is this life-size, or a model? If it is a model, then now big is the actual bridge you've created this model for?
Note: Be prepared to read your paragraph prior to the physical testing of your bridge.
Schedule
April 7th
You will be given a few sheets of scrap foam core in class. We will be do some demonstrations in class. Before coming to class (for homework) do an experiment to see what kind of strong structures you can make. Use the things in your house. Don't buy anything. Cardboard boxes, scraps of foam core from Samimy's room, Elmer's glue, etc.
Bring your research and designs. You must have 3 comprehensive (and different) bridge designs. Bring your experiments and drawings to class on the 19th. The drawings should be done with a ruler and be neatly done in the sketchbook.
IN SHORT, HOMEWORK (Due 19th):
1. 200-300 word paper.
2. 3 bridge designs (you will need 3 drawings for each design. 9 total.)
3. Your paper needs to be signed by your parent/guardian. In pen.
Come to class with white glue and a sharp knife & your drawings and experiments. This will be the only studio day. along with your drawings and text/paragraph.
Feb 21st
Final Critique. We will need you to bring a camera (or have a friend) shoot video documentation of your bridge being tested.
Rubric
Craftsmanship 40 pts
Design/Creativity 40pts
Weight Limit 20 pts (For every 25 lbs your bridge holds, you receive 5 pts)
-------------------------------------
Total Possible Points 100
Note: your bridge must hold at least 50 lbs to get a passing grade.
Research
Below are images and a video of the critique from previous years. Pay attention to both the designs of the bridges, and the set-up of the tables. This will help you in designing your bridge appropriately. Note: the pieces of wood screwed to the side of the table extend down 1' (foot). You may have part of your bridge rest against this surface to help distribute stress/weight.
Also below you will find links to short and long video’s about bridges bridge building the history of bridges and bridge as metaphor. Along with a couple of videos on how to work with foam core. and even a game!

Bridge Builder GAME!!!
Description
You need to build the bridge to get the creatures to the other side. The bits the creature can walk along are build along the green line. Your bridge needs to be made out of triangles to be effective. Otherwise it will just break. Use the orange fixed anchor points to support your bridge.
Instructions
Build the bridge and press T to test it. Press escape to go back to building it. Click on pieces to delete them. Click on anchor points and press delete to delete those. Use the "reset ball" button to place the ball where it landed last.
