Grouping Materials

Looking Around 2 — sorting and classifying everyday objects, connecting to observation activities around the home and classroom.

• We can group materials by properties like hard/soft, natural/man-made, or see-through/not see-through.
• Natural materials come from nature (wood, cotton, clay). Man-made materials are created by people (plastic).
• Grouping helps us understand and use materials better.

Verbal: Grouping means sorting things into sets based on a shared property.

Symbolic: Group A: Natural (wood, cotton, clay) | Group B: Man-made (plastic, nylon).

Level 1 — Natural vs man-made

Level 1 — Hard vs soft materials

Metal and stone are hard; cotton and sponge are soft.

Level 1 — See-through vs not see-through

Glass and clear plastic are see-through; wood and metal are not.

Level 2 — Sorting activity

Sort classroom objects into "natural" and "man-made" groups.

Level 2 — India

Cotton and wool (natural, from plants/animals) vs plastic toys (man-made) sold in Indian markets.

Sort these into natural and man-made: wooden spoon, plastic spoon, cotton towel, nylon rope.

Step 1 — Wooden spoon: from a tree — natural.
Step 2 — Plastic spoon: made in a factory — man-made.
Step 3 — Cotton towel: from cotton plant — natural.
Step 4 — Nylon rope: made in a factory — man-made.
Answer: Natural = wooden spoon, cotton towel. Man-made = plastic spoon, nylon rope.

• Name one natural material and one man-made material.
• Group these by hardness: sponge, rock, cotton, steel.
• Is glass see-through or not?

Stretch: Can a material be both natural and hard? Give an example (like wood or stone).

Revision tip: Pick five things from your bag and group them as natural or man-made.
