Clouds form when warm air rises and the water vapor in the air condenses into tiny liquid water droplets or ice crystals. Different types of clouds exist at varying heights in the sky and can range from fluffy white clouds to dark gray storm clouds. An experiment demonstrates how smoke particles from a blown out match can form a cloud when trapped in a bottle, showing how water vapor condenses around particles in the air to become visible as clouds.

2. 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.

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

5. Experiment Materials: matches and a pump bottle Step1: make sure there is at least one centre meter of water in the pump bottle Step2:light the match then hold it over the pump bottle then blow it out. step3:quickly close the pop top so the smoke is trapped. and then...

6. ...It makes a cloud! This is what happened: v The reason we could see the cloud in the bottle was because all the particles were all gathered up into little groups and if they were all alone then we wouldn’t be able to see them.
