This long sleep is called hibernation (winter sleep). During this time they use the stored up food usually fats in their bodies.

the bowls in the sunshine for about 2 hours. Touch the sand and water in the bowls. Now keep the bowls inside. After an hour, touch the sand and water in the two bowls.

In a given period, sand and water do not absorb the same amount of heat. We observe that the sand gets warmer faster than water. It also cools down faster than water. So, naturally the nights are much cooler than days in the desert areas.

2) a. Light a candle and look at the flame. It burns upwards. b. Place hands by the side of the candle flame and then above it. We find that

the air by the sides of the flame is not as hot as the air above. It shows that hot air rises up. c. Take a balloon and press it so that no air inside it. Tie the mouth of the balloon to that of an empty bottle with the help of a rubber band. Take some boiled water in a beaker and place the bottle in the breaker. When the air in the bottle is heated it becomes light and rises up, which inflates the balloon. This shows that air when heated becomes lighter and rises up.

3) Put some wet clothes to dry in separated rooms. In one room do not turn the fan on. In other room turn the fan on.

The clothes will dry faster in the room with the running fan. The water in the wet clothes evaporates into water vapour. This shows that water evaporates faster when there is movement in the air.

4) Take 2 bottles of same size. Pour the same quantity of water in them. Keep one bottle in the sun and the other in the shade. Watch the water level in the bottles after an hour. We can see that the water in the bottle kept in the sun evaporates faster. This is because it gets more heat.

5) Take two towels of the same size. Wet them with water. Keep one of them folded. Spread the other one. Allow them to dry. After sometime we observe that the one which was spread dries up faster. This is because in that towel the surface exposed is larger.

G.S. - 4 29

6) Clothes dry quickly on a dry summer day than on a rainy day. During the rainy season, the air is full of water vapour. So it cannot take out more water from the wet clothes. On a dry day, air has no moisture in it. So it can take out more water from the wet clothes.

7) Take a kettle filled with water and keep it on the fire. Let the water boil. When the steam comes out, allow it to strike against the pan, we will observe that water droplets are formed on the pan. This is because condensation of water vapour into droplets of water.

river, thus storing water in the lake. It creates a permanent reservoir of water for use at a later time. The dam must be watertight. The dam has some way of releasing water in controlled amounts as it is needed. Water is allowed to flow downwards. The force of the flowing water turns the turbine, which in turn spins the metal shaft in the electric generator that produces electricity. When water is flowing downwards, the picture is amazing and the water looks like milk. The sound of waterflow makes us deaf for sometime !

threads are interlaced at right angles to form a fabric or cloth. The longitudinal threads are called the warp and the lateral threads are the weft or filling. Cloth is usually woven on a loom, a device that holds the warp threads in place while filling threads are woven through them. The way the warp and filling threads interlace with each other is called the weave. Woven cloth can be plain, or can be woven in decorative or artistic design.
