Learning Objectives
By the end of this lesson, you should:• Be able to clearly define the three
classifications of wood• Be able to describe how to join wood
together• Be able to describe how the term
’sustainable’ and how it relates to wood

Classifications of Wood
Wood comes in three different classifications:
• Hardwood• Softwood• Manufactured Board
Design and Technology @ Nightingale Academy
Softwood – Natural Wood
• Natural material• Comes from evergreen trees• Tends to give longer lengths than
hardwoods• Tends to be cheaper than hardwoods
Design and Technology @ Nightingale Academy
Examples
• Scots Pine• Red Ceader• Larch
Design and Technology @ Nightingale Academy
Hardwoods – Natural Wood
• Natural material• Comes from deciduous trees• Tends to be more expensive than
hardwoods• Tends to be harder wearing than
softwoods
Design and Technology @ Nightingale Academy
Examples
• Oak• Mahogany• Teak
Design and Technology @ Nightingale Academy
Manufactured Boards – Man made wood
• Comes in large boards• Manufactured by gluing wood or
wood fibres together• Produces constant strength and
texture• Easy to work with• ‘Veneers’ can be used to add a more
aesthetic finish
Design and Technology @ Nightingale Academy
Example
• Blockboard• Hardboard• MDF• Plywood

Task 1
• Complete question 1 on your worksheet in your class book in as much detail as possible
5 Minutes

Sustainability
Timber is often referred to as a sustainable material.
But why????????
Design and Technology @ Nightingale Academy
Sustainability
This is when the environment is thought about when designing a product.
• Transportation costs• Material usage• Sourcing of material
Design and Technology @ Nightingale Academy
Timber and the Environment
• Trees can be replanted to replace those cut down for their timber
• Wood can easily be recycled/reused• Manufactured boards can be used to
limit the number of trees which are cut down
Design and Technology @ Nightingale Academy
Timber and the Environment• Forest Stewardship
Council• Promote
responsible management of the worlds forests
Design and Technology @ Nightingale Academy
Task 2
• Complete question 2 on your worksheet in your class book in as much detail as possible
10 Minutes
Design and Technology @ Nightingale Academy
Joining Wood
• Traditional wood joints• Knock-down fittings
Design and Technology @ Nightingale Academy
Traditional Wood Joints
• Give the product extra structural strength
• Time consuming• Tend to be on more expensive
product
