CLOUDS

Clouds come from air that is warm and full of water vapour. Water vapour is

water in the form of a gas. It gets into the air when the Sun heats water in lakes,

rivers, and oceans. The water evaporates, or turns to water vapour. As the Sun

heats the air, the warmer air rises. But it’s colder higher up, and the water

vapour turns to tiny water drops or bits of ice. The water and ice make clouds in the sky. The particles of water or ice are so

small that they float in air.

Some clouds are white and fluffy. Some clouds are dark and gray. Some clouds are close to Earth. They float across the sky in sheets. Some clouds go up high like mountains. Watch out for dark clouds. They could mean a storm is coming.

ExperimentMaterials: matches and a pump bottle

step 1: make sure the bottle has about 1cm of water in it

Step 2: light the match then blow it out allowing smoke to rise then try to make the smoke enter the bottle.

Step 3:close the cap and squeeze the bottle really hard and see what happens

Smoke and match

Aim: to create a cloud in the bottle.
