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

5 Master leamer status

4 Made a good showing

3 Demonstrates some knowledge of the subject

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 2

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

 

Day 3

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

 

Day 4

Groups complete and submit plans for approval. Upon approval students will create a material list.

 

Day 5

Groups will purchase materials from the class lumberyard. Construction of bridges will begin.

 

Day 6

Bridge construction.

 

Day 7

Bridge Construction.

 

Day 8

All groups will videotape the bridge strength test.

 

Day 9

Groups will review video and prepare a report of the performance of their bridge.

 

Day 10         Groups will present their report to class.

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)
