Presenting Innovations

Overview

This final lesson in the unit helps students communicate their engineering solutions. Students present their innovations and explain the scientific/sustainability ideas behind the design adaptations, linking cause–effect to energy use, materials, and environmental impact.

Learning intentions

• Students will present their engineering product clearly using evidence from their planning and testing.
• Students will explain adaptations they made and why those changes improved sustainability.
• Students will describe how sustainability concepts guided their design choices.
• Students will respond respectfully to audience questions and refine their thinking based on feedback.

Success criteria

• I can describe my solution and what problem it solves in a clear, organised way.
• I can name at least two adaptations I made and explain the reason for each.
• I can link my design to sustainability (for example: reducing waste, saving energy, using materials responsibly, longer lifespan).
• I can answer questions using specific details from my project work.

Curriculum links

• Science — Engineering principles and processes: using evidence to evaluate and communicate design decisions.
• Students practise presenting information for different audiences through clear structure and scientific reasoning.
• Students use scientific language to explain relationships between changes made and outcomes.

Lesson structure (45 minutes)

1. 0–5 min · Set-up and success criteria review. Teacher shows the day’s presentation routine and success criteria; students review their rubric/checklist and organise notes for speaking.

2. 5–10 min · Mini model of a strong presentation. Teacher demonstrates a short example (about 45–60 seconds) showing: problem → design → adaptations → sustainability link → evidence from testing; students notice the sentence structure on the board.

3. 10–28 min · Student presentations (Round 1). Teacher divides class into two halves; while one half presents, the other half uses a feedback sheet to record one strength and one question.

• Students present their project (about 1.5–2 minutes each) covering: a) What my innovation is and who it helps b) What I changed (adaptations) and why c) Sustainability ideas I addressed d) What evidence shows my adaptation worked (observations/data from their testing)

4. 28–38 min · Feedback and adjustment moment. Teacher prompts quick reflection: “What will you say next time if you could improve?” Students update their notes with one feedback suggestion and practise a one-sentence answer to a likely audience question.

5. 38–44 min · Student presentations (Round 2) or rapid-fire Q&A. Teacher swaps groups for those not yet presenting, or runs rapid-fire Q&A at stations if timing is tight. Students take turns answering questions with evidence-based explanations.

6. 44–45 min · Exit ticket (instant check). Students complete a short written prompt: “One adaptation I made that improved sustainability was… because…”. Teacher collects for next steps and overall unit reflection.

Resources

• Student presentation checklist/rubric (printed)
• Feedback sheets for audience members (strength + question)
• Timer or countdown clock for each presentation segment
• Student project artefacts (models, posters, labelled diagrams)
• Evidence pages (testing results, photos, measurements, design iterations)
• Markers, sticky notes, and clipboards
• Board/slide template for “Problem–Adaptations–Sustainability–Evidence”
• Seating plan for efficient presentation grouping

Assessment

• Formative assessment during presentations: teacher listens for sustainability explanations that clearly connect adaptations to outcomes.
• Feedback sheet evidence: audience questions indicate understanding and help students refine scientific reasoning.
• Exit ticket checks: ensures every student can articulate one sustainability-linked adaptation with a clear cause–effect reason.

Differentiation

• Provide sentence starters on the board: “I adapted my design by…”, “This supported sustainability because…”, “After testing, I noticed…”.
• Allow multimodal presentation options: speaking with a labelled diagram, or brief demonstration of the model while narrating key points.
• Support for students needing structure: offer a three-part speaking plan (Problem, Adaptations, Sustainability + Evidence) and allow notes on cue cards.
• Challenge extension: ask presenting students to justify trade-offs (for example: “What did you choose not to change, and what impact would that have?”) and to explain how their design reduces environmental impact over time (not just immediately).
• EAL/SEN considerations: accept point-form explanations and provide a word bank for sustainability terms (reduce, reuse, recycle, energy, materials, waste, lifespan, efficiency).
