Name five objects which can be made from wood.
Answer 1: –
Because of its various properties like hardness, ability to float on water and insulation towards electricity, wood is used to make a number of day to day things.
Five objects which can be made from wood are:
a). Furniture, like tables and chairs
e.) Decoration Pieces
Select those objects from the following which shine:
Glass bowl, plastic toy, steel spoon, cotton shirt
Objects shine when they reflect the light that falls on them. From the given objects, Glass bowl and steelspoon shine.
Match the objects given below with the materials from which they could be made. Remember, an object could be made from more than one material and a given material could be used for making many objects.

Topics Covered in NCERT Solutions for Class 6 Science Chapter 4 – Sorting Materials into Groups:-
- OBJECTS AROUND US
- PROPERTIES OF MATERIALS
– Soluble or Insoluble?
– Objects may float or sink in water
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.
