“The important thing is to never stop questioning.” – Albert Einstein
The students of Class III participated in an activity to find out how the movement of Earth causes season changes as well as day and night. With the guidance of their teachers, they conducted an activity during their online classes in which they made a model of the Earth using materials like a globe, orange, play dough or ball and a torch. The torch represented the sun and the ball represented a model of our planet Earth. When the light from the sun (torch) falls on the Earth (ball), that part of the Earth gets lighted up and it is supposed to be daytime. The opposite part of the Earth does not get the sunlight and it is supposed to be night-time on the other side.
The students then made the model of the Earth move around itself and it was seen that the part of the Earth that faced the sun started facing the other way and did not get any light. Thus, it was considered night-time now. The kids concluded that the movement of Earth around its axis causes day and night. The students then made the model of Earth move around the model of the sun in an oval path. They observed that sometimes the Earth moved away from the sun and sometimes it moved closer towards it. When the Earth moved closer, it got more heat and light from the sun which caused the summer season. When it moved away it got less light and heat which caused the winter season. It was thus inferred that the movement of Earth around the sun causes season changes.
The students did the activity with a lot of vigour and curiosity. They asked a lot of questions about the movement of Earth and exchanged interesting facts as well. It could be seen that they grasped the concept very well. The activity was hence, a complete success.
