Curriculum Information

• Learning Area: Science
• Curriculum Strand: Material World
• Level: Level 5 – The New Zealand Curriculum
• Big Idea: The structure and properties of matter are related and help us understand the behaviour and uses of different materials.
• Achievement Objective:
  Investigate the chemical and physical properties of a range of substances and use this knowledge to explain how and why the substances are used in the ways they are.

Lesson Overview

This 60-minute lesson encourages Year 10 students to synthesise their understanding of metal properties by researching and creating an engaging poster on a chosen metal from the periodic table. Students will consider both the scientific (lustre, malleability, density etc.) and practical (uses in industry or daily life) sides of their selected metal. The lesson is hands-on, collaborative, and aligns with future-focused learning in the New Zealand context.

---

Learning Intentions

Students will:

• Identify and describe key physical and chemical properties of metals.
• Research and communicate scientific knowledge about one specific metal.
• Recognise connections between the properties of a metal and its practical uses in Aotearoa New Zealand and globally.
• Present scientific information creatively and clearly through a visual medium.

---

Success Criteria

By the end of the lesson, students should:

• Accurately describe at least three key properties of their selected metal.
• Clearly link the metal’s properties to one or more of its common uses.
• Complete a visually engaging and informative poster suitable for display.
• Work respectfully and productively in pairs or small teams.

---

Materials Needed

• A3 paper or card (per group)
• Colour pencils, markers, glue sticks, scissors
• Access to printed or digital copies of the Periodic Table
• Metal profile info sheets (for those without internet access)
• Devices for online research (if available)
• Timer or visual countdown (for activity pacing)

---

Prior Learning

Students have previously covered:

• Definitions and examples of key metal properties: lustre, ductility, malleability, conductivity, sonorousness, melting point, density.
• Basic structure of the Periodic Table including identification of metals and nonmetals.
• How to conduct basic scientific research and summarise key findings.

Lesson Plan (60 Minutes)

⏱ 0-10 mins: Activate Knowledge – Quickfire Challenge

Activity: Properties Pop Quiz (Kahoot or Paper-Based Option)

• Students work in pairs to answer a short quiz reviewing key properties of metals.
• Questions include visuals (eg: shiny spoon vs dull plastic) to draw connections between theory and real-world items.
• Class discusses one or two surprise answers as a bridge into the main task.

Key Teacher Prompts:

• "What makes metals ideal for conducting electricity?"
• "Why don’t we make hammers out of plastic?"

⏱ 10–15 mins: Introduce Main Task – Poster Briefing

Teacher Explanation:

• Students will create a poster about one metal from the Periodic Table.
• They can choose from: Aluminium, Iron, Copper, Zinc, Nickel, Lead, Silver, Gold, Titanium, Tin (others may be proposed for approval).

Poster must include:

1. Name and symbol of the metal
2. 3+ physical/chemical properties (e.g. ductility, density, melting point)
3. At least two practical uses and why its properties suit those uses
4. One fun/scientific fact (e.g. NZ coinage, Māori pounamu analogy, tech use)
5. Visuals (drawn or printed)

Assign or allow students to choose their metal. Hand out a “Poster Planning Sheet” to scaffold their research and layout ideas.

⏱ 15–40 mins: Collaborative Creation – Poster Making

Students work in pairs or trios (depending on resources and class dynamic).

• Encourage efficient division of labour: one student researches, another sketches, another writes up.
• Teacher circulates to ask guiding questions:
  • “What property makes this metal good for that use?”
  • “Could you show that with a diagram?”
  • “Does this connect back to what we discussed last week?”

⏱ 40–50 mins: Gallery Walk – Sharing Learning

• Students place posters on desks or around the room.
• Half the class stays to explain their poster (“The Experts”), the other half circulates (“The Investigators”), then switch roles.
• Provide question prompts:
  • “Why did you choose this metal?”
  • “What’s the most surprising thing you learned?”

Differentiation Tip: Print questioning stems on small cards for students who need help with structured conversation.

⏱ 50–55 mins: Reflection and Discussion

Whole-class debrief using Padlet, whiteboard, or think-pair-share:

• “What properties came up most often?”
• “Which metal is most useful in daily life in NZ?”
• “What surprised or intrigued you today?”

Record ideas under key competencies: Thinking, Participating and Contributing, and Using Language, Symbols and Texts.

⏱ 55–60 mins: Wrap-Up and Homework

• Celebrate a few standout posters (balance creativity and depth).
• Explain homework:

  “Write a short paragraph on a metal we didn’t cover today and how its properties would make it useful for some job in 2040. Think futuristic!”

Optional extension: Create an interactive science wall by adding QR codes linking to student-created audio clips explaining their metal in Te Reo Māori or English.

Assessment Opportunities

Formative Assessment:

• Teacher questioning during creation phase
• Peer-to-peer explanation during Gallery Walk
• Poster quality and content as rich evidence of conceptual understanding and literacy in science

Links to Key Competencies:

• Thinking – Making connections between structure and function
• Relating to Others – Peer collaboration
• Participating & Contributing – Gallery walk explication
• Using Language, Symbols & Texts – Communicating scientific ideas clearly

---

Reflective Teacher Prompts (Post-Lesson)

• Which metals sparked the most curiosity/discussion?
• Did the students make effective connections between properties and real-world applications?
• Which posters best demonstrate deeper thinking?
• What might we explore next – alloys, conductivity in circuits, or recyclable metals?

---

Optional Extensions

• Invite a local engineer or tradesperson to talk about use of metals in their role (e.g. builder, jeweller, mechanic, welder).
• Compare traditional Māori use of natural materials vs modern metal technologies – mātauranga Māori integrated discussion.
• Digital version: turn posters into short videos or infographics for online sharing with whānau.

Final Note

This lesson isn't just about metals — it's about turning curiosity into applied science, building knowledge into design, and making future choices from informed understanding. It embodies the NCEA pathway shift toward clarity, connection, and relevance — and it puts learners in charge of using science to explore their world.
