Q83

A teacher demonstrates an experiment to his class how a mirror becomes hazy when we exhale air on it. Which general objective of teaching EVS is being achieved through this experiment ?

  1. (1) Explain the concept of cold or hot air to children.
  2. (2) Explain the concept of inhalation and exhalation.
  3. (3) Demonstrating experiment to the children.
  4. (4) To engage children in exploratory and hands-on activities to acquire basic cognitive and motor skills through processes of observation, classification and inference.Correct answer

Solution.

CBSE answer: (4)

Answer: (4) Engaging children in exploratory and hands-on activities to build observation, classification and inference.

  1. The stem asks for a general objective of EVS teaching, not the content of this one experiment.
  2. Watching the mirror cloud up trains children to observe and draw an inference.
  3. Options (1) and (2) are specific content points, and (3) is the method, not the aim.

Trap: (2) fits the experiment, but it is a specific concept, not a general objective.
