Finishing Touches

Overview

In this sixth lesson of the eight-lesson “Designing with Robotics” unit, students complete the decoration and refinement of their robotic structures. Building on earlier planning and construction, they will make deliberate choices about colour, pattern and added features while checking that decoration does not interfere with movement, sensors or other functions. Each group will finish with a structure ready for testing.

Learning intentions

Students will:

• select and safely use suitable materials, tools and techniques to decorate a robotic structure
• explain how material properties and added features may affect the structure’s function
• refine a design by comparing it with the group’s intended purpose and success criteria
• work cooperatively and communicate making decisions using appropriate technology terms

Success criteria

• I can decorate my structure neatly and safely.
• I can explain how my decoration supports, rather than prevents, its function.
• I can test moving parts, sensors and connections after making changes.
• I can complete a structure that is ready for testing next lesson.

Lesson structure (45 minutes)

1. 0–5 min · Hook and retrieval. Open with the hook and learning intention slides showing a plain robotic structure beside a carefully decorated one, and ask, “Can decoration make a robot work better, worse or just look different?” Students briefly recall one function their structure must perform and share one possible decoration choice with a partner.

2. 5–11 min · Model safe refinement. Use the safety and refinement slides to demonstrate selecting lightweight, secure materials; measuring and marking before cutting; and keeping wheels, sensors, switches, wires and moving joints clear. Teacher models a quick function check before and after adding a paper feature, thinking aloud about weight, balance, friction and accessibility. Students identify one possible risk or function problem in their own structure.

3. 11–15 min · Plan the finishing touches. Distribute the decoration and refinement planner and, if groups need clearer responsibilities, hand out the Group Role Cards. Students sketch or list two decoration ideas, choose materials, predict one effect on function and allocate roles such as materials manager, maker, safety checker and recorder.

4. 15–32 min · Decorate and refine. Refer to the making steps and visual theme examples as groups work on their structures. Students measure, mark, cut, join and attach decorations, using recycled or reusable materials where practical; they pause after each major change to check stability, movement, sensor access and safe operation. Teacher circulates, checks tool use, questions design decisions and prompts groups to remove or adjust anything that blocks function.

5. 32–38 min · Function and quality check. Display the testing checklist slide and ask groups to complete a quiet “ready check”: structure is secure, decoration is attached, moving parts can move, sensors and controls are accessible, and no sharp or loose pieces create a hazard. Students make one final improvement and record the change and its reason on the worksheet.

6. 38–45 min · Gallery share and exit reflection. Groups place structures where others can view them and use the final the gallery discussion and plenary slides prompts: “What design choice supports the robot’s purpose?” and “What must we test next lesson?” Students give one positive, specific comment to another group, then complete the worksheet’s exit reflection before packing materials away safely.

Resources

• the Designing with Robotics lesson deck
• the decoration and refinement planner
• the Group Role Cards
• Existing robotic structures and components
• Recycled cardboard, paper, bottle tops, fabric and lightweight craft materials
• Coloured pencils, markers, rulers, glue, masking tape and child-safe scissors
• Device or robotics kit instructions, if used in the unit
• Storage tubs and labelled group trays
• Safety goggles where required by classroom risk assessment

Assessment

• Observe whether students select suitable materials, use tools safely and keep decoration clear of moving parts, sensors and controls.
• Question groups during making: “What property does this material have?” “Will it add weight or friction?” and “How will you know the structure is ready?”
• Review the planner and final structure for a clear decoration choice, a recorded refinement and evidence that the structure is ready for testing.

Differentiation

• Provide visual guides in the visual theme and step-by-step guide slides with photographs or simple drawings of suggested themes such as nature, transport or space. Keep instructions short, numbered and supported by icons.
• Offer pre-cut shapes, larger-handled scissors, glue dots, masking tape and lightweight materials for students who need reduced fine-motor demands. Allow students to dictate ideas or record them through labelled sketches rather than extended writing.
• Pair students strategically, read worksheet instructions aloud, provide a quiet workspace and use a clear sans-serif font with generous spacing for dyslexic learners. Check understanding privately and give one instruction at a time.
• Support language development with sentence starters: “We chose ___ because…”, “This may affect function by…” and “Our next improvement is…”. Extension students may research a more complex decoration technique, such as layered structures, repeated patterns or carefully balanced moving features, and explain how it could be adapted without affecting robot function.

Extension

• Advanced students research one more complex decoration technique and create a small sample or labelled sketch before deciding whether it is suitable.
• Students compare two groups’ decoration choices and justify which better balances appearance, sustainability, safety and function.
