Temperature and Smell   Materials Required: Paper towel Perfume Refrigerator A molecule is the smallest particle of a substance, made up of one or more atoms held together by a force.

This indicates that perfumed molecules can be smelled more easily, when you put some on your warm skin....

Soil an Invaluable Resource One of the Earth’s most valuable basic resource is the soil. It is formed of several layers of ‘Humus’, made of decaying leaves etc. It covers the first layer of soil called the ‘Topsoil’. In this layer decayed plant and animal material is broken down by bacteria, insects and earthworms thus making it fertile. Below this lies the ‘Subsoil’ containing lesser organic material and reachable only by...

A potato stays hot for long while a toast doesn’t. Assuming, thick food retains its warmth for a longer period of time, a thicker pancake should keep its heat longer than a thinner one. With the help of an adult, carry out...
