Material Evidence Review

Overview

This lesson is the final check-in for the “Marvelous Materials Exploration” unit. Students will demonstrate their understanding of material properties, sorting/classifying, and state change recording through a short practical assessment and an evidence portfolio reflection.

Learning intentions

• WALT (We Are Learning To) investigate and describe key properties of everyday materials using simple tests.
• WALT (We Are Learning To) sort and classify materials based on observable properties.
• WALT (We Are Learning To) explain what we learned using our science journal and portfolio evidence.

Success criteria

• I can test a material (e.g., feel, sink/float, magnet, bend/fold) and record what happens.
• I can sort materials into groups and say why using property words (such as rough/smooth, hard/soft, absorbent/waterproof, bendy/stiff).
• I can share one example from my journal/portfolio and explain what it shows about materials.

Curriculum links

• Science understanding: identifying and comparing observable properties of materials and how these properties can be used for practical purposes.
• Science inquiry skills: asking questions, conducting simple investigations, using observations to record and communicate findings.
• Scientific reasoning: using evidence from tests to justify a classification.

Lesson structure (30 minutes)

1. 2 mins — Welcome + WALT Teacher briefly revisits the unit goal: “materials have properties we can observe and test.” Students choose a preferred response option (talk, point, or write).

2. 5 mins — Quick refresh: property word wall Teacher shows picture cards of common properties (rough/smooth, hard/soft, bendy/stiff, waterproof/absorbent). Students do a fast “show me” practice by choosing the correct card when the teacher demonstrates a short action (e.g., squeeze sponge, fold paper, pour water on fabric).

3. 10 mins — Practical assessment: Property Investigation mini-task (hands-on) Students rotate through or complete one brief station with 2–3 materials (teacher decides based on available resources). Each student records:

• Material name (or photo label)
• What they observe during 1–2 tests (e.g., magnet yes/no, sink/float in water tray, bends or not, absorbs water or not)
• A simple sentence starter or oral response option Teacher uses an observation checklist for whether students: follow steps safely, use property language, and record an outcome.

4. 8 mins — Sorting & Classification Challenge (summative evidence) Provide a set of mixed material samples/photos. Students sort into two groups of their choice (teacher prompts: “Which property can we use to group them?”). Students then choose one group and explain why using an evidence statement (sentence starter available). Students place their sorting sheet into their portfolio.

5. 3 mins — Exit ticket: “One thing I know” Students complete a quick exit ticket:

• Draw one tested material
• Circle one property
• Answer orally or with a short written line: “I know because I saw…” Teacher checks understanding and listens for evidence-based reasoning.

6. 2 mins — Portfolio check + next steps Students add one piece of evidence to their “Materials Portfolio” section (sorting sheet, investigation record, or journal page photo). Teacher notes next-step needs for future units.

Resources

• Small set of material samples (e.g., paper, cardboard, plastic, metal foil, sponge, fabric, wood stick, rubber band)
• Magnets, trays for testing sink/float, water in a controlled container
• Tongs or safe tools for handling materials (as needed)
• Sorting cards with photos and/or material labels
• Property recording sheets with large icons and sentence starters
• Student science journals (or journal pages to photograph/submit for portfolios)
• Observation checklist (teacher use)
• Timer, visual schedule, and WALT display
• Data collection clips/folios for 7 students

Assessment

• Formative: teacher observation during tests (safety, using property words, recording outcomes) and exit ticket conversation.
• Summative: practical investigation record plus sorting/classification sheet added to the student portfolio.
• Evidence to portfolio: one investigation page, one sorting page, and one journal/portfolio reflection piece.

Differentiation

• Support: provide guided templates with picture prompts, pre-labeled material cards, and step-by-step visual instructions. Offer a “fill in the property” option instead of full sentences.
• Target: encourage independent recording using the sentence starters and property word bank; students choose which test they will describe.
• Extension: add one extra test question (e.g., “Which material would you choose to keep an item dry? Why?”) and record a reason using evidence from the station.
• Autistic learners: reduce verbal load during instructions, use clear visual routines, offer predictable station roles, and allow oral recording options.
• Dyslexic learners: provide sentence starters, fewer words per record sheet, use labels/photos instead of spelling-heavy tasks, and allow recording via speech-to-text or teacher scribing if needed.
• EAL learners: show property demonstration visuals, use real objects for vocabulary anchors, and allow pointing/matching explanations before writing.

Assessment Evidence Expectations (what “good” looks like)

• Students correctly match at least one test outcome to a property (e.g., “It bends” → bendy, “Water soaks in” → absorbent).
• Students sort materials using a single consistent property and can explain with evidence (“I saw it sink” / “I saw it absorb water”).
