Design and Technology PGCE Session 1

Three dimensional movement

Session 3


Three dimensional movement

• Wheels, axles and rotary motion

• Energy sources

• Criteria for DMAs

• Reclaimed and bought materials

• Curriculum planning


Making wheeled vehicles

• The chassis

• The wheel and axle assembly

• In-board source of power

• Body work


Chassis

• Must be rigid

• Clean holes for axles

• Use a variety of materials and components


Wheels

• Types of wheels – card, wood, plastic, lids, cotton reels, table tennis balls

• Thickness and size of wheels –

influences the qualities of the movement produced


Axles

• Types of axles – paper fasteners, drawing pins, wire, dowel, straws

• Must be straight

• May be rotating or fixed


Framework

• Wood strip frame

• Art straw frame

• Cardboard box frame

• Papier-mâché frame

• Balsa wood frame

Consider finishing techniques


Energy sources

• A stretched elastic band• A falling weight• A battery powered motor• A blown-up balloon• A twisted elastic band and

propeller• Pushing or pulling


Renewable Energy Sources

• Hydroelectric• Biomass• Geothermal• Solar• Wind• Tidal• Wave


Activities using rotary movement

• Vehicles

• Spinning toys

• Roundabouts

• Fairground rides

• Spinning wheels

• Machinery


Belt and Pulley system


Task 1

Create a rotating fairground ride using a

battery source


Technological impact

• Industrial Revolution of the 18th and 19th century

• Automated machinery

• Steam power

• Primarily the textile industry

• Social, economic and technological changes


Progression through mechanisms

• Wheel• A water wheel• A water wheel driving a machine


Design and make criteria

The design and make criteria will influence the end product and will enable an evaluation to take place.

It must take into account the context of the activity and the needs of the client. Problem solving activities will either be open ended or closed tasks.


Providing a context to develop criteria

• Discussion• School visit• Survey of the school

environment• Stories or poems• Audio visual material• Internet research• IDEAs type activity• Problem solving• Photographs or paintings


Developing criteria

• Carry out surveys to find out needs or problems

• Observe and/or interview

• Develop an awareness of the needs of others

• Be able to look objectively at a situation

• Clarify needs in line with practical considerations


Questions

• What needs does the client have?

• What resources are available? (materials and tools)

• How much time do we have?

• What is the scale of the outcome?

• Do we have space available for the practical work?


Evaluating

• Evaluating the completed product in light of the set criteria

• Evaluating the partially completed product

• Evaluating the procedures while designing and making


Carrying out evaluations

• Objective evaluations – will usually involve some form of measurement and possibly a scientific investigation or experiment.

• Subjective evaluations – depend more upon opinion than measurement but are still valid.


Task 2

Design an activity to investigate the success of various wheels and

axles


Materials

The greater the range of materials the children have experienced the more choice they will have when working on Design and Make Assignments.

Experience may be gained by simply experimenting with the materials or by an introduction to their properties in a focused practical task.
