Students of grade four started unit 2 with a lesson on natural disasters. They watched videos related to different natural disasters. This was followed by an illustrative discussion on earthquakes. Some stationery was placed on a white board with a mobile on vibration mode. This caused the board to vibrate and the items placed to move. Through this hands on activity the students were able to see the tremor and shaking of stationary placed on a white board and connect themselves to a real life experience for a moment during earthquakes.
