Introduction to the
project

Model a bridge using cargo bridge.

Explain to the pupils how
long the unit lasts, the main activities and the outcome.

Teacher explains the task pupils are to build a bridge using 5mm pine and PVA glue.

The bridges had to span 20 cm and could be 8 to 12 cm wide.

The bridges will then be progressively loaded
with weights till they reach their breaking point.

 Teacher shows the class several examples of peer group work

 Pupils to use cargo bridge to design a bridge. 

Pupils to gain confidence
in designing and modelling bridges.

 Pupils learn to work within financial constraints.

 Pupils get a feel for structures and the use of triangulation.

 

Pupils are enthusiastic
and enjoy the topic.

to open the software

Teacher demonstrates using the various tools needed to draw a bridge in the drawing board

Teacher demonstrates to
pupils how to perform a load test

Teacher demonstrates to
the pupils how to develop and improve the design.

Pupils develop it and
improve it.

Pupils to gain confidence
in designing and modelling bridges.

Pupils learn to work
within financial constraints.

Pupils think in more depth
about structures and the use of triangulation.

 

Pupils are enthusiastic
and enjoy the topic.

Five classifications of
forces

Understand the nature and effects of: Bending

Shear

Torsion

Compression

Tension

 

 

 

 

Teacher explains what a market
stall lesson is.

Teacher splits the class
in to five groups.

Teacher demonstrates the
theory and concepts of one force only to each group. Groups generate
presentation material for their given force.

Manager gives presentation
at their market stall; other group members attend presentations at the other
market stalls.

Groups reform and write
definitions of all five classifications of forces.

Pupils are able to name
each force.

Pupils are able to understand and describe each force.

L4 – Pupils gather
information independently + views of users

Pupils gain confidence in CAD are
creative and can express their ideas.

Pupils look at one another’s work and discuss good
points and ways to improve bad point in their work.

 

 

 

 

 

 

7

Pupils to generate and model a range of ideas

Pupils
to chose their best design

Teacher explains how to be creative and innovative in their ideas

Pupils generate four ideas for their bridge designs using WestPoint

bridge designer

Teacher uses examples from
peers.

Groups work to discuss
criteria used in selecting the idea to develop further and to go on to
manufacture.

 

Pupils to gain confidence in
designing and modelling bridges.

Pupils learn to work
within financial constraints.

L4 – Pupils generate
alternative
ideas using sketches, models and/or ICT, and make choices could be developed
in their head.

L5 – imaginative ideas. 

L6 – refine or change ideas in the light of
their research – this could include testing, modeling as
the idea develops.

Planning for manufacture
using CAD

Design the templates for
making the bridge using 2D design.

 

.

Teacher demonstrates how
to draw the chosen idea in 2D design Teacher demonstrates using the path
 tool, explode function and how to edit nodes in their drawings.

Pupils draw their chosen
bridge design using 2Ddesign and print it in A4 landscape

 

L4 – Outline what and
how they are going to make it.

L5 – Produce dimensioned drawings / patterns / sequence making stages

L6 – Produce formal drawings/with details of manufacture, CAD – as appropriate.
