Making a Boat

Each material has its own characteristics or properties. These include strength, flexibility, transparency, ability to float or sink in water, and being waterproof.

• A strong material can support heavy weights without breaking easily, while a weak material breaks or tears easily.

• A flexible material is easily bent and somewhat returns to its original state after the bending force is removed. A stiff material is not easily bent, and breaks when we try to bend it.

• A waterproof material does not absorb water.

• A material can block light or allow light to pass through it.
