Key Words Relevant for Science Chapter 4  Sorting Materials into Groups Class 6: –

Hard: Objects that do not change their shape easily and are not easily broken are hard objects.

Insoluble: A substance is said to be insoluble when it does not dissolve in another substance. For example, oil doesn’t dissolve in water.

Lustre: Lustre is the property of the object to shine. Freshly cut metal surfaces reflect light that falls on their surface making them lustrous.

Material: Materials are matters that are required to make something. For example, clothes are made from fabric. Hence, fabric is the material required to make clothes.

Metals: Elements that have certain properties like lustre, ductility and good electrical conductivity are known as metals. Metals have many uses. For example, copper is used to make wires.

Opaque: Objects through which the other side is not visible are called as opaque objects. They do not allow light to pass through them, making it impossible to see through.

Rough: Objects having an uneven surface are called rough. Example: Sand paper

Soluble: Substances that dissolve in any other substance easily are soluble, like, sugar dissolves in water.

Translucent: Objects through which we can only see partially and the objects on the other side are not clearly visible, are known as translucent. Example: Oiled paper.

Transparent: Objects through which we can see clearly are known as transparent objects. Example: glass, air, etc.
