Ghulan and Sheeta are thrilled to go to their new class

After some time, Madam Vidya, their science teacher,
enters the class and starts interacting with the students to
draw their attention to many things they use in their daily
life. She asks, “How are they similar to or different from

6.2 How to Group Materials?
Activity 6.2: Let us group
? Group the objects shown in Fig. 6.1 based on any common
property, such as shape, colour , hardness, softness, shine,
dullness or materials they are made up of.
The earliest pottery found in the Indian subcontinent dates
back to 7,000 to 8,000 years in the Ganga plains (Lahuradewa)
and in Baluchistan (Mehrgarh). About 4000 BCE onwards,
Sindhu-Sarasvati developed techniques of wheel-
turned pottery production, pigmentation, application
of protective or decorative coats (called ‘slips’) of
multiple colours, decorative painting, etc. These
techniques became further sophisticated during the
Sindhu-Sarasvati (also known as ‘Harappan’) Civilisation
(2600–1900 BCE), with a bright red surface
painted with black-coloured designs displaying
geometric patterns, and aquatic and terrestrial
animals. The clay used for making pots, dishes,
bowls and other items was carefully selected
and cleaned, sieved, kneaded, turned over a
wheel and finally baked in kilns (baked clay
is called ‘terracotta’). Pots were used for various
purposes, from cooking to storage of food grains,
oil, ghee, and so on. Some very large storage
jars and other pottery items are exhibited at the
National Museum, New Delhi.
others?” All things are made up of some materials like paper ,
wood, cloth, glass, metal, plastic, clay, and so on.
Any substance that is used to create an object is referred to
as material.
Activity 6.1: Let us identify
Make a list of objects you see around and also write the
names of the materials they are made up of in Table 6.1.
Based on everyday observations, one can conclude that
objects are made up of various materials.
