materialsproperties_wordle

Some materials are better for a purpose than others. This is because different materials have different properties.

resistant_fragile

A resistant material is difficult to break, but a fragile material breaks easily.

rigid_flexible

A rigid material doesn’t bend easily, but we can bend a flexible material.

ElasticRubberBand1_460

An elastic material returns to its original shape after we bend it or strech it.

transparent1_460

Some materials are transparent, which means that light can pass through them.

OpaqueBrickWall1_460

When light can’t pass through a material, we call it opaque.

WaterproofRainBoot1_460

Some materials are waterproof, which means that water can’t pass through them.

pan2

Heat passes through some materials easily and these materials are called heat conductors (metal in the pan). Materials that heat can’t pass through easily are called heat insulators (wood or plastic in the handle).

pan

The pan is made of metal because it is a heat conductor. The handle is made of wood (or plastic) because it is a heat insulator.
