Materials Evidence Overview

Overview

This lesson draws together learning from the unit “Marvelous Materials Exploration” through a simple, student-friendly assessment overview. Students show what they know by completing short practical tasks, sharing observations, and selecting evidence for their materials portfolio.

Learning intentions

Students will:

• use simple scientific vocabulary to describe properties of everyday materials
• complete hands-on checks for how materials respond to forces like pushing, bending, stretching, and soaking
• sort and classify materials using given properties
• explain their thinking and choose portfolio evidence from the unit

Success criteria

Students can:

• tell which property (such as hard/soft, rough/smooth, waterproof/absorbent) a material shows
• record observations clearly using pictures, labels, and/or short sentences
• sort materials into groups and justify the group using an oral explanation
• select at least two pieces of evidence for their Materials Portfolio

Curriculum links

• Science: investigate observable properties of materials and describe changes using informal or simple scientific language
• Science: use science inquiry skills such as making observations, recording data, and sharing findings
• Scientific literacy: communicate findings in ways appropriate to their stage (talking, drawing, labelling)
• Reasoning: identify patterns (materials in the same group share a property)

Lesson structure (30 minutes)

1. 0–3 min — WALT + warm-up prompt Teacher shows a tray of familiar materials (paper, plastic sheet, sponge, foil, cardboard, cotton). Students do a quick “Think-Pair-Share” and answer: “One thing I noticed about a material is…”

2. 3–7 min — Safety and assessment overview Explain that today is an “assessment overview” using a mix of teacher observations, quick exit tickets, and portfolio evidence selection. Model how to show thinking: point to evidence, say it, then record/draw.

3. 7–15 min — Practical task carousel (hands-on) In small rotations, students complete two short checks:

• Test 1: Bend/press (cardboard vs plastic vs foil): students observe and choose a property such as “bends easily” or “does not bend easily.”
• Test 2: Water test (sponge vs paper vs foil): students observe and choose “soaks up” or “does not soak up.” Students record using a guided template with icons (e.g., hard/soft; rough/smooth; soaks/doesn’t soak).

4. 15–22 min — Sorting & classification challenge Students receive a small set of mixed materials and a sorting mat showing two property columns (teacher selects based on class readiness). Students sort and then give a 10–20 second oral explanation using starters (e.g., “I put it in this group because…”).

5. 22–27 min — Scientific observation journal check + exit ticket Students complete a short exit ticket: draw one material, circle the property it showed in today’s tests, and write/say one sentence (or use a sentence starter). Teacher uses an observation checklist while students work.

6. 27–30 min — Portfolio evidence selection + next steps Students choose two portfolio pieces (photos/worksheets/journal entries from earlier lessons) and tell the teacher which one best shows their learning. Teacher confirms next steps for individual learning plans.

Resources

• Material samples: paper, cardboard, plastic sheet, foil, sponge, cotton fabric, tissue
• Sorting mats with two property headings (picture-supported)
• Guided recording templates with icons and sentence starters
• Clipboards/pencils, coloured pencils for circling properties
• Water tray, small cups, paper towels, gloves if needed
• Timer for carousel rotations
• Exit ticket sheets (reduced-text) and/or oral response option cards
• Student portfolio folders (Lesson 15 work samples accessible)
• Teacher observation checklist (simple “can/can’t yet” notes)

Assessment

• Teacher formative observations during carousel and sorting (property language used, accurate grouping, participation)
• Exit ticket (draw/circle/short sentence or oral explanation) to check understanding of properties and communication
• Summative evidence for portfolio: selected samples that show testing, recording, and explanation across the unit

Differentiation

• Support: guided templates with pre-drawn icons, sentence starters, and a model example of “This material soaks up water because…”
• Target: reduced icon count (students add one label), independent sorting with teacher prompts only if needed
• Extension: add a third group label (e.g., “stretchy” vs “not stretchy”) and students test an extra material to justify a new classification
• Autistic learners: predictable routine with visual schedule (carousel → sorting → exit ticket → portfolio), clear turn-taking, quiet corner for regulation, sensory breaks as required
• Dyslexic learners: oral response option, reduced-text recording sheets, audio teacher modelling, and extra time for writing; accept drawing and labelled diagrams instead of full sentences
• EAL learners: word bank with pictures (hard/soft, rough/smooth, absorbs/waterproof), allow responses in first language with a partner or teacher translation support
