Classifying Materials
Plan and conduct an investigation to classify different kinds of materials by their observable properties
Lesson
Set out your lesson
“Classifying Materials means grouping everyday materials by properties you can notice and test. We will practise once together, then check a fresh example.”
Bring to the table
- 4–6 small material samples (wood, metal, fabric, plastic, paper)
- Sorting mat labeled by property words
Extra for the adult
Worked example. Metal may be hard and shiny. Fabric may be soft and flexible. The same object can fit different groups depending on the property you choose.
Optional challenge. For Classifying Materials, re-sort with a second property.
What to notice. Keep one parent note: materials grouped by property; support used. This session samples classification, not mastery of materials science.

Check understanding
- Design a simple test to compare one property across several materials
- Record observations in a table or chart during the investigation
- Classify the tested materials into groups based on the results
“Can your child test a set of objects and sort them by properties like whether they float, conduct heat, or are magnetic?”
