In order to introduce the concept of ‘axis’ and ‘movement’ of earth in an Elementary class more effectively, a teacher should :
(A) ask students to draw a figure of earth and draw a line in its middle to show its axis.
(B) demonstrate and discuss using globe.
(C) piercing a big needle through a ball and discuss its similarity.
(D) use a map to discuss about both the concepts.
Choose the appropriate option :

Correct option is B

The correct option is (c) (C) and (D) piercing a big needle through a ball and discuss its similarity and use a map to discuss about both the concepts.
Option (A) is not the most effective way to introduce the concept of 'axis' and 'movement' of Earth to an Elementary class. Drawing a line on a flat piece of paper does not accurately represent the three-dimensional nature of the Earth.
Option (B) is a good way to introduce the concept of 'axis' and 'movement' of Earth. A globe is a three-dimensional model of the Earth, and it can be used to show how the Earth rotates on its axis.
Option (C) is another effective way to introduce the concept of 'axis' and 'movement' of Earth. Piercing a needle through a ball and discussing its similarity to the Earth can help students to understand that the Earth has an axis around which it rotates.
Option (D) is not an effective way to introduce the concept of 'movement' of Earth. A map is a two-dimensional representation of the Earth, and it does not show how the Earth rotates on its axis.
Therefore, the most effective way to introduce the concept of 'axis' and 'movement' of Earth to an Elementary class is to use a combination of Option (C) piercing a big needle through a ball and discuss its similarity and Option (D) use a map to discuss about both the concepts.
