Appendix E-1 SCIENCE COMPREHENSION OF A STORY

Thirsty Crow

Name of the student: Roll No: Name of the school: Class: Gender: Division: Read the story given below and answer the following questions

Once a thirsty crow was flying in the air to find some water for drinking, finally it

could locate a jar with little water in it. Crow could see only some water in the jar. It

flew away and picked up a small stone (pebble) and slowly dropped it into the jar. It

again picked up another pebble and dropped it in the jar. Third time it could pick up a

piece of coal available around and dropped into the jar. Then crow could pick up a

piece of chalk, a small broken plastic spoon and also a Harda (batasa-a sweet solid

sugar made piece) and dropped one after the other into the jar. Water level in the jar

increased slowly. A happy crow picked up some more pebbles and dropped into the

jar. Finally the water level rose up to the brim. This way crow could drink water and

while flying away it kicked the jar. Jar tumbled down and water started flowing

downwards. Crow could see the pebble there and also a piece of coal, broken plastic

spoon, well soaked piece of chalk as they were. Crow also saw Harda but small in

size, picked it up and flew away.
