Year 9 Autumn Revision Q&A

These flashcards cover key concepts and definitions from the Year 9 Autumn Revision notes, including carbon offsetting, tools for metalwork, manufacturing processes, properties of materials, and art design.

Carbon Offsetting

Compensating for carbon dioxide emissions by funding projects that reduce emissions elsewhere.

Examples of Carbon Offsetting

Planting trees and investing in renewable energy.

Importance of Carbon Offsetting

Helps reduce overall greenhouse gas emissions and supports sustainability.

Marking Out Tools

Used to measure and mark precise lines before cutting or shaping materials.

Examples of Metalwork Marking Out Tools

Scriber, engineer’s square, and centre punch.

Purpose of a Centre Punch

To make a small dent that guides a drill bit.

CAM

Computer-Aided Manufacturing.

Advantages of CAM

High precision and fast production speeds.

Disadvantages of CAM

Expensive setup and possible job losses due to automation.

Annealing

Heating and cooling metal slowly to make it soft and ductile.

Hardening

Heating and cooling metal quickly to make it harder but more brittle.

Tempering

Reheating hardened metal slightly to reduce brittleness and increase toughness.

Common Output Components

Devices like LED, motor, and buzzer used in circuits.

Function of a Buzzer in a Circuit

Produces sound when current flows.

Function of an LED

Producing light in response to electricity.

Examples of Hardwoods

Oak and beech.

Properties of Oak

Strong, durable, and long-lasting, making it a good choice for flooring.

Typical Use for Mahogany

High-quality furniture and decorative items.

Examples of Softwoods

Pine and cedar.

Use of Pine in Construction

Lightweight, easy to work with, and inexpensive.

Properties of Cedar

Naturally weather-resistant and contains oils that prevent rot.

Plywood

Layers of wood veneer glued together with grains at right angles.

Properties of MDF

Smooth, easy to shape, and used in furniture.

Disadvantages of Chipboard

Weak and easily damaged by water.

Ferrous Metals

Metals that contain iron, are magnetic, and can rust.

Examples of Ferrous Metals

Mild steel and cast iron.

Non-Ferrous Metals

Metals that do not contain iron, are non-magnetic, and resist corrosion.

Examples of Non-Ferrous Metals

Aluminium and copper.

Inspiration for Art Nouveau

Nature — flowing lines, flowers, and organic shapes.

Charles Rennie Mackintosh

A Scottish architect and designer famous for his Art Nouveau work.

Famous Design by Mackintosh

The Glasgow School of Art or his tall-backed chairs.

Layout Paper

Used for sketching design ideas.

Tracing Paper

Used for copying and overlaying drawings.

Cartridge Paper

Thicker and better quality paper used for art and general drawing.

Grid Paper

Used for technical drawings and graphs.
