Model bridges rubric

Things to consider.
- Research the type of forces the bridge is subjected to. They include gravity, compression, tension.
- Discuss how the bridge design minimizes the impact of these forces on the overall structure.
- Give reasons why this type of design was chosen.
- Identify 5 different types of bridges from around the World and identify the type of bridge represented by the model.
- Use only the material provided
- Draw a detailed scaled drawing in a 1:2 ratio.

Research Student has conducted little or no research. Unable to identify forces that affect bridges and doesn't have a perspective on reasons for bridge design. Shows slight understanding of the reasons behind bridge design. Can identify 2 types of bridges. Information is taken from
some sources, student can identify 2 forces that affect
their bridge, some historical
perspectives and some
reasons for bridge design
are noted. Can identify 4
bridge types..		 Information is taken
from multiple sources.
Student can identify
all forces that affect
their bridge, identify
reasons for the bridge
design and can identify at least 5 bridge types
.
Design Plan is not drawn to scale.
Materials are not identified.		 Plan has some materials
labeled. Some parts are
drawn to scale.		 Most materials are labeled. Most of the bridge is drawn to scale. Outstanding design. Covered all requirements: design is labeled, draw to scale and proper building material is
used.
Completed model Student used more than the resources provided. Bridge cannot support 5g. Bridge is not constructed to scaled plan. Student used a little more than the resources provided. Bridge can support 10g or under for less than 5 minutes Student used just the right amount of the resources provided. Bridge supported just under 15g and just under 5 minutes Bridge is somewhat constructed to scaled
plan.		 Student used just the right amount of the resources provided. Bridge can hold 15g or more for 5 minutes or more. Bridge is constructed to scale and is aesthetically pleasing.
Bibliography No bibliography shown Some sources missing. An attempt has been made to write a bibliography with some sources being relevant and credible All sources listed but some lack credibility or relevance. All sources are listed and are highly relevant to the topic and credible.
