Concepts

This study delivers 1 primary concept and 2 secondary concepts.

Primary concept: Technical Drawing and Design Communication (DT-KS2-C002)

Type: Skill | Teaching weight: 2/6

Technical drawing involves representing design ideas using conventions that communicate information about how a product looks, how it is constructed and how its parts relate to each other. At KS2, pupils learn to use annotated sketches, cross-sectional diagrams, exploded diagrams, pattern pieces and computer-aided design to communicate their ideas clearly and accurately to others who will make or evaluate the product.

Teaching guidance: Teach specific drawing conventions including labelling, dimensioning and cross-sections. Practice exploded diagrams to show how components fit together. Introduce appropriate computer-aided design tools for generating and presenting design ideas. Discuss why designers need to communicate their ideas clearly to others, such as when a design is made by someone other than the designer. Compare technical drawings with artistic drawings to highlight different purposes. Key vocabulary: annotated sketch, cross-section, exploded diagram, prototype, pattern piece, computer-aided design, dimension, label, scale, proportion Common misconceptions: Pupils may treat all drawing in DT as artistic expression rather than technical communication. Establishing that technical drawing has specific conventions and purposes helps. Some pupils may find exploded and cross-sectional diagrams conceptually challenging; building up from physical disassembly of real objects helps develop the mental model.

Differentiation

Model response (Entry): I drew a phone stand with a back support and a front lip. Labels: 'back support — card', 'base — wood', 'front lip — card strip to stop phone sliding'.

Model response (Developing): Design A is a simple angled back rest, 12cm tall and 8cm wide. Design B is a box shape with a slot. I chose Design A because it uses less material and is easier to make, but Design B would be more stable. I'll add a wider base to Design A to fix the stability problem.

Model response (Expected): I drew a front view and a side cross-section showing how the layers fit together. I included all measurements in cm, listed materials for each part, numbered the assembly steps, and drew an exploded diagram showing how the three pieces slot together. I also noted where I would use glue and where I would use screws.

Secondary concept: Functional and Aesthetic Material Properties (DT-KS2-C007)

Type: Knowledge | Teaching weight: 2/6

Materials have both functional properties — characteristics that determine how they perform in use, such as strength, flexibility, conductivity and waterproofness — and aesthetic properties — characteristics that determine how they appear and feel, such as colour, texture, pattern, translucency and surface quality. At KS2, pupils learn to consider both dimensions when selecting materials for a design task, understanding that a material must be both functionally suitable and appropriately appealing for the product to succeed. This concept extends KS1 material knowledge by making the functional/aesthetic distinction explicit.

Differentiation

Secondary concept: Product Investigation and Analysis (DT-KS2-C008)

Type: Process | Teaching weight: 2/6

Product investigation involves systematically examining existing products to understand their purpose, intended users, materials, construction methods, mechanisms, aesthetics and how successfully they fulfil their design intent. At KS2, investigation is more structured and analytical than at KS1: pupils use frameworks to compare products, consider both strengths and limitations, and relate findings to their own design work. Understanding how existing products solve design problems is a valuable source of design inspiration and technical knowledge.

Thinking lens: Evidence and Argument (primary)

Key question: What is the evidence, how reliable is it, and what conclusions can it support? Why this lens fits: Investigating existing products requires pupils to gather evidence through disassembly and testing, then build an argument about why the product was designed as it was — evaluation is a structured claim supported by evidence from investigation. Question stems for KS2:

What evidence supports this claim?

Is this a fact or an opinion? How can you tell?

Is this strong evidence or weak evidence? Why?

Can you structure your argument: claim, evidence, reasoning?

Secondary lens: Structure and Function — Technical drawing (annotated sketches, exploded diagrams) communicates not just what the product looks like but how its structure will enable its function — annotating design decisions makes the structure-function reasoning explicit.

Session structure: Design, Make, Evaluate

Design, Make, Evaluate

The core Design & Technology cycle. Pupils investigate existing products and user needs, design a solution with clear specifications, plan the making process, construct using appropriate materials and techniques, test against the design brief, and evaluate the outcome with suggestions for improvement.

investigate → design → plan → make → test → evaluate Assessment: Design portfolio including investigation findings, annotated design with specifications, making log, test results, and evaluative conclusion comparing outcome to original brief. Teacher note: Use the DESIGN, MAKE AND EVALUATE template: investigate existing products to understand how they meet a need. Guide pupils to create a design specification, produce labelled designs, plan the order of making, and use tools and materials with increasing accuracy. Include testing against the original specification and a structured evaluation of the finished product. KS2 question stems:

What is the design specification, and how does your design meet it?

What tools and techniques will you use, and why?

How accurately have you followed your design?

How well does your product meet the specification? What improvements would you make?

Design and Technology: Structures

Design brief: Design and make packaging for a small product (e.g. a chocolate egg, a piece of jewellery, a toy). The packaging must protect the product, display it attractively, and include the product name and information. Materials: card (various weights), coloured paper, clear acetate (for windows), tape, glue Tools: scissors, ruler, pencil, scoring tool (adult supervised), set square Techniques: net drawing, scoring and folding, tab construction, surface design, prototype testing Safety notes: Scoring tools (craft knives or bone folders) require adult supervision. All scoring should be done on a cutting mat. Demonstrate safe scoring technique: ruler firmly held, score away from fingers. Evaluation criteria:

Does the packaging protect the product?

Can you see or access the product?

Does it include product information?

Is the construction neat and well-finished?

Why this study matters

Designing packaging for a real product teaches shell structures (structures whose strength comes from their shape rather than internal framework) while connecting to real-world design. Pupils disassemble existing packaging to understand nets, folds, and tabs. They then design packaging for a specific product, learning that form follows function -- the packaging must protect, display, and inform.

---

Pitfalls to avoid

Net drawn too small for the product -- always measure the product first and add tolerances

Tabs too small to create strong joints -- minimum 1cm tab width

Forgetting to include product information on the packaging -- design the graphics as well as the structure
