small group activities, focus on positive dialogue and assigned
group roles.
○ Students are strongly engaged with a range of multimedia
presentations, small group focus and hands on materials.
 Intellectual Quality
○ Active construction of knowledge through varied KLA approach
and a hands on building activity
○ High order thinking encouraged and supported through
evaluation and analysis
○ A focus on the metalanguage of engineering, specifically for
bridge building

What are bridges for?
What is involved in building a bridge?
What is important about bridges?
What type of bridges are there?
What problems are there when building
bridges?
What are some famous bridges?
What sayings / cliches do you know of that
involve bridges – what do these sayings
mean?
Lesson 1 - activity
Based on the discussion collectively
define and create a mind map for
bridges. Scribe this mind map into
student work books.
 - online mind mapping tool http://www.mindmeister.com/

Lesson 2 - Comprehension
Early Bridges
In ancient times and among private peoples a log was thrown across a
stream, or two vines or woven fibrous ropes (the upper for a handhold
and the lower for a footwalk) were thrown across to serve as a bridge.
Later, arched structures of stone or brick were used; traces of these,
built from 4000 to 2000BC, have been found in the Mediterranean
region. The Romans built long, arched spans, many of which are still
standing. Bridges built in the middle ages usually rested on crude stone
arches with heavy piers (intermediate supports) that were a great
obstruction to river traffic , and their roadways were often lined with
small shops.
The best known early American design is the New England covered bridge,
since wood was abundant and cheap, and did not demand trained
masons. Colonial American bridge builders were willing to run the risk
of rot or fire in exchange for such savings in time and manpower. By
1779, most bridges began to be built of cast and wrought iron. The
disadvantage of cast iron bridges is its low tensile strength.
Questions
When were bridges first used?
What supports did early bridges use?
What were the advantages of wooden
bridges?
Make a list of technical words used in this
report.
What type of sentence is the first sentence?

interviews them about their
accomplishments. For an additional
challenge the component of ‘double figures’
can be integrated.

Lesson 6 - Australia
Read the article and collect some
statistics and facts.
 http://www.sydneyharbourbridge.info
 Use these answers to create a numbers
crossword.
 Discussion question: How does the
Sydney Harbour Bridge represent
Australian culture?

Lesson 7 - design

Brief: construct a bridge using the materials
provided.
 Choose a bridge design that would suit a wide
river, the area has heavy rain through the year.
 Council would like to have the lowest cost
possible.
 It also needs to be strong, easy for cars to
cross.
 It should be able to withstand natural disasters
common to this area (floods, earthquake and
strong winds).
Lesson 7 - Design
Make at least 3 sketches of bridge
designs that could suit the brief.
 Choose one and list next to it reasons
why this design was chosen.
 Make a bigger sketch of the chosen
design, label to show what materials
would be used.
 Create a well presented document /
page that states the design features of
this bridge (eg strong due to....)

Lesson 8 - Build
Use the materials provided to construct your chosen
design.
 Assign roles to your group to ensure that all group
members are involved and are positive contributors to the
team.

 Project manager – keeps the group on task and on time,


acknowledges good work from team
Architect – draws the designs
Foreman – in charge of the construction
Researcher – uses various sources to find out about which
designs and materials would best suit. This person will also be in
charge of creating the design features summary.
Builder – assists the foreman and architect in construction.
Presenter – this person helps where needed during the session
but is also responsible for reporting back to the class about the
groups final product and process.
Lesson 9 – Share, analyse
Groups move their construction to span the
space between two desks. Using model
cars the bridges are tested for ease of
access, strength and ability to withstand
natural disaster (wind, earthquake).
 Record findings on a class table. Copy
findings into books.
 Groups comment on their construction’s
results – eg “so strong because design /
materials”

Lesson 10 - evaluation
Discussion based on the questions below.
Which bridges were more successful?
Would these bridges be equally as
successful in different conditions (eg a
bridge over a road, in swamp land)?
 Would these bridges be costly to build?
 In a different colour add to your initial mind
map on bridges.
 Where to next? Is there anything else that
you would like to learn about bridges? How
could you discover this information?
