Describe simple physical properties of everyday materials such as hard/soft, stretchy/stiff, shiny/dull, rough/smooth, waterproof/absorbent, transparent/opaque
Every material has properties. A property is a word for how it feels or looks. Touch it or look closely, then describe it. A rock is hard. A sponge is soft. Hard is the opposite of soft.
A metal spoon is hard and shiny. It feels smooth, and it will not bend. A wooden table is hard and a little rough. Dull is the opposite of shiny. An old coin looks dull.
A sponge feels soft and rough. It squishes when you squeeze it. It soaks up water fast, so it is absorbent, not waterproof. A brick is rough and dull.
A rubber band is stretchy and soft. It stretches when you pull it. A glass window is transparent and smooth. Light passes right through it. Wood is opaque. It blocks light.
Properties matter for real reasons. A raincoat is waterproof, so rain does not soak through.
Properties are useful, not just describing words. A raincoat is waterproof, so rain does not soak through and you stay dry. A sponge is absorbent, so it soaks up spills. A window is transparent, so daylight comes in. Properties decide if a material fits the job.
Materials have properties like hard, soft, shiny, rough, stretchy, transparent, and waterproof. Use these words to describe what you touch and see.

You know the six material names. Now you need words that describe them. Every material has properties: words for how it feels and looks. The game is: look at it, touch it, squeeze it, describe it.
You squeeze a cushion and it squishes down. Which word fits?
