Concept:The core aim of teaching EVS is to develop scientific temper through direct exploration, hands-on activities, and process skills like observation and inference.
Explanation:The experiment makes children observe the mirror turning hazy when they exhale on it.
This is a simple hands-on activity that does not require any special equipment.
Students watch the effect, think about why it happens, and connect it to moisture in their breath.
Such an activity builds basic cognitive skills (reasoning) and motor skills (handling the mirror).
It also encourages curiosity and an inquiry-based approach to learning.
Option B is too narrow—it focuses only on cold/hot air.
Option C is also narrow—it focuses only on inhalation/exhalation.
Option D describes the act of demonstration, not the general objective of EVS teaching.
Only option A covers the broad goal of exploratory learning through observation, classification, and inference.
Answer:A. To engage children in exploratory and hands-on activities to acquire basic cognitive and motor skills through processes of observation, classification and inference.
