Earth and Space Showcase

Overview

Lesson 20 of 20 focuses on students presenting their final Earth and Space projects. Students demonstrate understanding of evidence-based science ideas, using appropriate scientific language, models or diagrams, and clear reasoning.

Learning intentions

• Students will present their final project clearly to an audience.
• Students will explain the scientific concepts and evidence that support their conclusions.
• Students will use scientific language to describe processes, patterns and outcomes.
• Students will reflect on feedback and identify next steps for improving their scientific communication.

Success criteria

• I can describe my main Earth/Space idea using accurate scientific terms.
• I can explain how evidence supports my explanation (not just opinions).
• I can show my model/diagram clearly and link each part to what it represents.
• I can listen to questions and respond respectfully and scientifically.

Curriculum links

• Earth and Space: investigate and describe scientific evidence and patterns related to Earth systems, including tectonic activity and plate boundaries.
• Scientific inquiry: plan and conduct reproducible investigations by identifying variables, assumptions and risks, and use results to justify claims.
• Science communication: describe and justify conclusions using scientific evidence and reasoning (aligned to the Inquiry Skills and Science Understanding focus of Year 8 Science).
• This lesson specifically strengthens students’ ability to describe and communicate scientific understanding developed across the unit.

Lesson structure (30 minutes)

1. 0–4 min · Set up and review goals. Teacher explains today’s focus: presenting final projects and using evidence to answer questions; students confirm what they will present and where their project materials are.

2. 4–8 min · Project rehearsal (quiet run-through). Teacher circulates to check each student’s clarity and supports students to practise: “My claim is… My evidence is… My explanation is…”

3. 8–18 min · Presentations (structured sharing). Teacher runs a short presentation routine: student presents for ~7 minutes, then answers 2 teacher prompts or audience questions; teacher uses a quick note-capture form (key claim, evidence, explanation).

4. 18–24 min · Feedback and improvements. Teacher provides 2 stars and a wish (2 strengths, 1 specific improvement) focusing on scientific accuracy, clarity of diagrams/models, and evidence-based explanation; student records one improvement they would make.

5. 24–28 min · Targeted question challenge. Teacher asks a targeted question linked to unit concepts (for example: “How does your evidence show the process/pattern?” or “What would you expect to see if the model were changed?”); student responds using claim–evidence–reasoning.

6. 28–30 min · Exit reflection (quick and individual). Student completes a short reflection: “The most convincing part of my project was… The evidence I used was… Next time I will…”

Resources

• Student project materials (poster, slide, model, booklet, annotated diagram)
• Project checklist handout (claim, evidence, explanation, diagrams/models, scientific language)
• Reflection sheet (2 stars and a wish + exit ticket prompts)
• Timer for presentations and practice
• Teacher feedback notes sheet
• Optional: rubric-style criteria strip (clarity, accuracy, evidence, responses to questions)

Assessment

• Formative: teacher observation during rehearsal and presentation using notes on claim clarity, evidence use, and scientific reasoning.
• Formative: targeted question responses to check understanding and ability to justify claims with evidence.
• Summative-in-practice: exit reflection identifying the most convincing evidence and one improvement to communication.

Differentiation

• Support: provide sentence starters for claim–evidence–reasoning and a diagram-labelling scaffold (e.g., “This part represents… because…”).
• Support: allow the student to present using their strongest modality first (spoken explanation supported by a labelled model).
• Extension: ask a deeper “what if” question (e.g., if one condition changed, what evidence would shift and why).
• Language/SEN/EAL: permit visual explanations (arrows, labels, short dot points) and allow extra rehearsal time; teacher offers targeted vocabulary prompts (process, evidence, pattern, model).

Notes for teacher (quick routines to keep time)

• Presentation structure to model aloud: “My claim… My evidence… My explanation… My answer to your question…”
• Keep feedback specific and actionable: name the diagram/model feature that needs improvement, and one way to strengthen evidence links.
