Step 1: Research Forces & Materials
Your teacher will assign your group a structure from the
following list:
| Suspension Bridge |
Beam Bridge |
Two-story home |
Skyscraper |
| Dome |
School |
Tunnel |
Dam |
Your design team will become the experts on that
structure and teach the rest of us about the critical design issues, including
dead loads, live load considerations, appropriate construction materials and
building techniques.
Start this process by assigning one force (tension, compression, shear, torsion)
and two building materials (concrete, wood, steel, fasteners, cables,
composites, iron, plastic/rubber) to each member of your group.
Each person should use the
Internet resources and at least one other resource to study their topics and answer
the questions on the designated worksheets.
Force Worksheet:
| Tension |
Compression |
Shear |
Torsion |

Materials Worksheets:
| Concrete |
Wood |
Steel |
Fasteners |
| Cables |
Composites |
Iron |
Plastic/Rubber |
Research Notes:
Do not print and turn in pages
from the internet. As you find useful resources, you have two choices
for note-taking techniques:
 | Takes notes on worksheets and other
paper, and make sure to document the source of each important piece
of information (URL, organization, date). |
| Copy applicable paragraphs,
definitions, and diagrams from the internet into a word document,
along with all source information (URL, organization, date) adjacent
to the copied information. |
| Make sure your own name and your
group's name is on each document you produce. |
Step 2: Discuss Design Issues
Meet with your group to discuss how (and where) the
forces and materials you researched are used in your structure.
|
As a team you will need to create several products
to help you teach the class what a design engineer must consider when
creating plans for a new structure or troubleshoot problems with an existing
structure. |
|
Each person must contribute to each portion of the
presentation, and each component needs a designated leader (production
manager). |
|
You will be evaluated on both individual work and
the groups final products. |
Step 3: Prepare Your Presentation
Begin planning your presentation.
|
Select a production manager for each
component of your presentation. That person is the facilitator, but
everyone must contribute to all products. |
|
Our class has visual, auditory,
and hands-on learners, so try to present key concepts through text, speaking,
diagrams, and activities. |
|
Create
design issues and questions for the class that challenge us to apply our new
knowledge. |
Use the following table to help you organize your five
products. The assessment
rubric will provide more details on what should be included.

Step 4: Class Presentation
Each production manager should introduce and facilitate their
component of your presentation, you must present as a team.
Remember: Get us
involved. Make us think!
You will be asked to evaluate your group's work, as well as your own
contribution.
