the air.’ 6° FORMS OF WATHR. Put a little water into a shallow basin, and let it stand in the sun. Where does the water go? Into what does it change ? What makes the little cloud that comes from the kettle in the picture ? 13. Forms of Water. Put some water into a shallow basin, and let it stand in the sun. The water will slowly change into vapor, and float away in the air. We cannot see vapor. The kettle in the picture is sending out vapor which changes into a little cloud. The vapor is in the clear space near the mouth of the kettle. 3 Vapor rises from ponds, lakes, brooks and rivers, but most of it comes from the sea. When the air is cooled enough, some of the vapor in it changes into large clouds, such as we often see floating above us. Were you ever in a fog? Did it look like water dust? Fog is a cloud near the earth. When enough vapor has changed into cloud, some of the particles of water fall through - Many particles run together and ior dies of rain. Have you ever seen any hail? Did it look like frozen rain ? When the air is very cold a part of ie vapor in it sometimes freezes into crystals or flakes of snow. If you will catch some snow- flakes on a piece of black cloth, you will find that they have very pretty shapes. At night, when the grass and stones are cold, vapor often floats against them and changes into dew. Breathe against a cold window and against a warm sleeve. Upon which does dew form? On very cold nights vapor freezes on grass and stones and forms frost. A part of the dew and frost is formed of vapor that. rises from the damp earth. The ice-coat on water forms first at the surface. If the freezing began at the bottom, many lakes and streams would become solid masses of ice. The fish in them would die, and even the summer sun could not melt the ice in deep water. What are the uses of ice ? Perhaps these words will help you to think of some of the uses of water :— kitchen, travel, mill, plant, river, ram, ocean, well.
