• A large transparent bowl (name this as A)
• Plastic Wrapper
• A weight
• A smaller container (this should be smaller than the bowl)(name this as B)
• A rubber band or piece of string

• Place the small container in the middle of the large bowl A.
• Fill the bowl A with little water, be careful not to spill into the small container B inside.
• Cover the bowl with plastic wrapper and fasten the plastic wrap around the rim of the bowl with your rubber band or string.
• Put a weight on top of the plastic wrap in the center.This will help for our experiment.
• Now put your setup in the sunlight.
• Let the child observer the setup now.
• After few hours, ask the child to observe.
• What is seen. You can see water s in the small container B.
• Ask your child to check the time and note down how long does it take for the water to evaporate and condense on the plastic wrapper.
• Where does the water go after it condenses on the plastic wrapper.

When water is heated, it changes from a liquid to a gas. This gas is called water vapour, and the process is called evaporation.

When plants give off water vapour, it is called transpiration. When water evaporates, it rises into the cooler air, collects, and forms clouds.
