NCERT Class 4 EVS Going to School

Chapter 1

 Going to School

Ö Collect some bricks. Lay them on the ground in a line as shown in the picture. Try walking on them. Was it easy ?

Ö Make a small bridge by tying 4 or 5 bamboo poles together. Ask your teacher to help you. Now walk on your bridge. How did you feel? Did you fall down? If you walk like this a few times, you will start finding it easy.

Ö Do you think it would be easier to walk on this bridge barefoot or with shoes or slippers ? Why ?

The Trolley

Everyday we have to cross the river to get to school. The river is wide and deep. There is a strong iron rope across the river. On both the sides it is tied tightly with strong trees or rocks. There is a trolley (an open

box made of wood) attached with the rope. Four or five of us sit in the trolley. A pulley helps the trolley to move across the rope. We reach the other side of the river in a short time

Letusdo

Observe pictures 1 and 2. In the pictures, children are pulling the buckets from the well. Can you tell the difference in both the pictures? Which would be easier – using the pulley or not using it to lift things?

Ö Look around you – where all do you see the use of pulleys? List them.

Ö With the help of a pulley, try and lift various things, as shown in the picture.

Cement Bridge

We often need to go across some water bodies, so we use bridges. These are made of cement, bricks and iron rods. The bridge may also have steps.

Ö How is this bridge different from a bamboo bridge?
