Grade: Date: 04/03/2026
Subject: Art and Design
Lesson Topic: show understanding of form, structure and scale
Learning Objective/s:
  • Describe the characteristics of form, structure and scale in three‑dimensional design.
  • Explain how material properties affect structural stability.
  • Apply scale ratios to convert model dimensions to real‑world sizes.
  • Construct a simple three‑dimensional model using appropriate materials and scale.
  • Evaluate a finished model for stability, proportion and visual impact.
Materials Needed:
  • Projector and screen
  • Sketch paper, pencils, erasers
  • Ruler and scale ruler
  • Cardboard, soft wood, hard wood, metal rods, acrylic sheets
  • Glue, scissors, hobby knife, measuring tape
  • Design checklist handout
  • Exit‑ticket slips
 Introduction:
Imagine turning a tiny model of a chair into a full‑size piece of furniture. Review the 2‑D shape and proportion concepts you explored last week. Today you will demonstrate understanding of form, structure and scale by creating a scaled model and justifying your material choices.
Lesson Structure:
  1. Do‑now (5'): Quick sketch of an everyday object focusing on its three‑dimensional form.
  2. Mini‑lecture (10'): Key concepts of form, structure and scale with visual examples.
  3. Scale calculation activity (10'): Students calculate real‑world dimensions from a given model size and ratio.
  4. Material selection & armature build (15'): Groups choose suitable materials and construct a basic framework.
  5. Form building (15'): Add surfaces, texture and detail to the armature.
  6. Peer review & stability test (10'): Test load‑bearing capacity and give feedback using the checklist.
  7. Reflection & documentation (5'): Complete the design checklist and record decisions.
Conclusion:
We recap how form, structure and scale interact to create stable, proportionate designs. For the exit ticket, write one way your material choice influences the model’s stability. Homework: produce a scale drawing of a small object using a 1:15 ratio and list the materials you would select.
