Children of Grade 1 were taken to the
Chemistry Lab to understand the characteristics of different materials. The teacher
displayed different kinds of materials like wood, plastic, steel, fabric,
cotton, glass, stone, copper sulphate, magnet, potassium permanganate etc.
Children were encouraged to observe carefully and investigate the materials.
They were asked to identify materials
with properties like smooth (table), rough (pumice stone), soft (cotton), shiny
(copper sulphate), grainy (potassium), transparent (glass, beaker), floats (wood),
attracts (magnet) etc. They understood that different materials have different
properties.
