(a) ANSWER:
The small water droplets on the outer surface of the glass come from the moisture present in the surrounding air. When the warm, moist air comes into contact with the cold surface of the glass, the water vapour in the air cools down and changes into water droplets. This process is called condensation and helps us understand how clouds form rain.
(b) ANSWER:
When the ice cubes are left in the glass for some time, they begin to melt because of the surrounding temperature. This shows a change in the state of water from solid to liquid. Heat from the air causes the ice to lose its solid form and become water. This process is called melting and is part of how water changes form.
(c) ANSWER:
If we heat water, it begins to boil and changes from a liquid to a gas, called steam or water vapour. This process is known as evaporation. It happens when the water molecules gain enough energy from heat to break free and rise into the air. This change in state from liquid to gas is part of the water cycle in nature.

Groundwater is the water that soaks into the soil after it rains and travels down through soil and rock layers. This water gets stored deep underground in natural spaces and is called groundwater. We use wells, tube wells and handpumps to draw this water for drinking, farming and daily use. It is an important freshwater source, especially where rivers or lakes are not nearby.

Rivers begin in high places like mountains and flow downwards due to gravity. Their journey across the land depends on the land’s shape. Rivers may curve, stop or spread depending on slopes, rocks and barriers. Through activities like the mustard seed experiment, we understand how rivers follow the natural path carved by the land, shaping valleys and collecting water into lakes and ponds.

The mustard seeds moved down the sloped paper surface, imitating how water flows from higher areas to lower ones. They did not follow a straight line but followed paths created by the surface. This helped in understanding how rivers begin in the mountains and follow downhill paths. The activity shows how land shape influences water flow, similar to river and stream movements in nature.

The mustard seeds did not move in a straight line; instead, they spread out and moved in different directions based on the surface's folds and slopes. This shows that water, like seeds, flows depending on the landform. Natural features such as hills, valleys and plains guide the water's direction, cRead more
The mustard seeds did not move in a straight line; instead, they spread out and moved in different directions based on the surface’s folds and slopes. This shows that water, like seeds, flows depending on the landform. Natural features such as hills, valleys and plains guide the water’s direction, causing rivers to bend, split or collect in different areas as they flow.
