What this dot point is asking

OCR J310 includes timbers among the six material categories. You need to know the three groups (natural hardwoods, natural softwoods and manufactured boards), the difference between hardwood and softwood, common examples, their properties, and typical uses. In the written exam this is tested by explaining the hardwood/softwood difference and by justifying a choice between solid timber and a manufactured board.

Hardwoods and softwoods

The split is botanical. Hardwood trees grow slowly, so the timber is usually denser, harder, more durable and more expensive. Softwood trees grow quickly, so the timber is usually lighter, cheaper and easier to machine. The classic trap is balsa: it is a hardwood (broadleaved tree) but is one of the softest woods, which proves the names are about the tree, not the hardness.

Manufactured (manmade) boards

Manufactured boards solve problems that solid timber has: they come in large sheets, are stable (resist warping), have no grain direction or knots, and are usually cheaper.

Properties and uses

Choose timber by weighing strength, weight, appearance (grain and colour), durability, workability and cost. Solid hardwoods win on appearance and durability for quality furniture; softwoods win on cost for general joinery; manufactured boards win on large stable panels and price for flat-pack products.

  • Cue. Broadleaved (deciduous) trees.

Q2. Give one advantage of a manufactured board over solid timber for a large furniture panel. [1 mark]

  • Cue. Large stable sheets, no grain direction or knots, resists warping, or cheaper.

A 2-mark question, one mark for the botanical difference and one for a typical property.

Hardwoods come from broadleaved (deciduous) trees, which grow slowly, so they are usually denser, harder and more expensive (for example oak, mahogany, beech). Softwoods come from coniferous (evergreen) trees, which grow faster, so they are usually less dense, cheaper and easier to work (for example pine, spruce).

Markers reward the source (broadleaved versus coniferous) and a property/cost difference. The classic trap is thinking the names always describe hardness; balsa is a hardwood but very soft, so the definition is botanical, not about hardness. Defining only the source caps the mark at one.

OCR J310/01 20224 marksA manufacturer is choosing between solid pine and plywood for the panels of a flat-pack bookcase. Explain two reasons they might choose plywood.
Show worked answer →

A 4-mark Explain wants two developed reasons for the manufactured board.

Reason 1, stability and large sizes. Plywood comes in large, flat sheets that are stable and resist warping, so wide bookcase panels can be cut from one sheet without joining boards, and they stay flat. Solid pine is narrower and can warp or split.

Reason 2, strength and consistency. Plywood's cross-bonded veneers give even strength in all directions and no weak grain or knots, so panels are reliable and cheaper to produce in quantity than selected solid timber.

Other valid points: cheaper than good solid hardwood, can be veneered for appearance. Markers reward two developed reasons tied to the bookcase. Two bare statements cap the mark at two.
