Technology - Grade 6
BC Rogers
Commencement
Content Standard from MST
Standard
#5
Students will apply technological knowledge and skills to design, construct,
use, and evaluate products and systems to satisfy human and environmental
needs.
Benchmark Standard
Content
Standard:
Engineering
design is an iterative process involving modeling and optimization
used to develop technological solutions to problems within given constraints.
Performance
Standards:
Identify
needs and opportunities for technical solutions from an investigation
of situations of general or social interest.
Develop
plans, including drawings with measurements and details of construction,
and construct a model of the solution, exhibiting a degree of craftsmanship.
In
a group setting, test their solutions against design specifications,
present and evaluate results, describe how the solution might have
been modified for different results, and discuss tradeoffs that might
have to be made.
Contents
Standards or Outcomes:
Students
will research bridge types and will complete a research work sheet.
Students
will design and construct a model bridge and will submit a packet
of thumbnail sketches and the working plan.
Students
will analyze their bridge performance and will submit a final report
analyzing their bridge performance.
Performance
Measures:
Grade
will be based on the following
- Bridge research
worksheet
- Bridge planning
and design
- Model bridge
- Weight held
- Bridge analysis
report
Rubrics

2
Worked a little on this subject
1 Lacks effort or understanding
Enabling
Activities:
- Students will
choose a bridge type by researching three basic designs and follow
problem-solving steps to design and build a bridge.
- Students will
build a bridge from early thumbnails sketches to the final wood prototype.
- Students will
video tape the strength test of their bridge, upon reviewing of the
tape, the students will prepare a report to present to the class on
their bridge performance.
During
2-week period students will research, build, and analyze
bridges.
The following enabling activities are designed for 6 Ih grade students
to complete in 10 days for 43 minutes each period.
Day
I
Introduction
to the bridge project. Students research bridges by the use of a bridge
video, classroom references, and personal experiences.
Day

Review
research from day 1. Students brainstorm and create thumbnails sketches
in small groups.
Day

Groups
choose a basic bridge design and work to complete a detailed plan
for construction.
Day

3. Before
1850, what were most bridges made of?
4. What
was the major disadvantage to iron bridges?
5. What
is now the most widely used material for building bridges?
The 3
basic designs of bridges are Beam, Arch, and Suspension.
In the
next 3 questions explain each type of bridge design.
6. Beam-
7. Arch-
8. Suspension-
9. What
is an important use of pontoon bridge?
10. What
is considered to be a moving bridge?
BRIDGE
BUILDING BRIEF
Here
is what you need to get started
Your
team must design, plan, and build a bridge to the measurements written
on the other side of this sheet. The bridge when complete will be tested
for the whole class to observer
Rules
for testing:
1. All
bridge plans must be approved by Mr. Rogers before any construction can
take place.
2. Any
material used on the bridge has to come from Mr. Rogers and the technology
laboratory.
3. All
bridges will meet the size requirements listed on the other side.
4. All
team packets must be turned in before any testing.
Evaluation:
1. 1 packet neatly completed (2 5 max)
2. 1
side view drawing (25 max)
3. 1
bridge (25 max)
4. Weight
held ranking (2 5 max)
Total
(Final grade) (1 00 max)
Team members:
Step
#1,. (Write the problem statement on the lines below)
Step
#2, (Write the result to be accomplished)
Step
#3- (Gather information about bridges through the bridge video and
personal experiences)
Step
#4. (Thumbnail sketch ideas for alternative solutions)
Step
#5. (Specify the best solution of the alternatives by circling one
of the thumbnail sketches)
Step
#6. (Test and tape your bridge)
Step
#7. (Review your bridge being crushed and show the class how it could
have been made stronger)
(Additional
Space for Sketching)

Bridge Analysis Worksheet
You are
now in the final stage of the bridge activity. Today you will review the
video of bridge testing. During the video record notes on this paper in
the form of written description, diagrams, and sketches. With these notes
your team must complete a one page report on your bridge design by using
the computers in the computer laboratory. Necessary information for the
report is as follows:
Building
team members
Bridge type Weight held
Weak points of the bridge
How could the bridge be stronger
Provide a computer drawing of the bridge
Staple your final report to this sheet (ONE REPORT PER TEAM)
