3. Materials One rubber glove (type used when washing dishes) Large pickle jar Tap water Matches (need adult’s help) A really thick, wide rubber band Desk lamp Big sheet of black construction paper
4. Steps of Investigation Pour some water so that it will cover the whole bottom of the glass jar Then we had to cut the rubber glove and cover the glass jar with the rubber glove. Then you need an adult to light a match. Then you have to count to 3 and blow it out and then put the match back in the glass jar for two seconds. To make a cloud you have to have some dust . You have to have a change in air pressure.
5. Results and Conclusions This picture shows that when you light a match it causes dust to appear in the air in the jar. When you push down on the rubber it changes the pressure and temperature in the jar. Water vapor condenses on the dust particles. And it becomes your own little cloud.
6. Condensation occurs when the surrounding temperature decreases suddenly. The reduction in pressure in the jar causes a decrease in the temperature inside the jar, which in turn causes the water vapor to change back to water . Water molecules condense and cling to the smoke particles suspended in the air inside the jar, forming water droplets. Thus a cloud appears in the jar.
8. Related Topics – Different Kinds of Clouds Stratus clouds are uniform grayish clouds that often cover the entire sky. They resemble fog that does not reach the ground. Usually no precipitation falls from stratus clouds, but sometimes they may drizzle. When a thick fog "lifts," the resulting clouds are low stratus. Stratus –low clouds
9. Altocumulus clouds Altocumulus clouds are middle level clouds that are made of water droplets and appear as gray, puffy masses, sometimes rolled out in parallel waves or bands. The appearance of these clouds on a warm, humid summer morning often means thunderstorms may occur by late afternoon.
11. This Is a Cirrus Cloud Cirrus clouds are thin, wispy clouds blown by high winds into long streamers. They are considered "high clouds" forming above 6000 m (20,000 ft). Cirrus clouds usually move across the sky from west to east. They generally mean fair to pleasant weather.
12. Cumulus Clouds Cumulus clouds are puffy clouds that sometimes look like pieces of floating cotton. The base of each cloud is often flat and may be only 1000 m (330 ft) above the ground. The top of the cloud has rounded towers. These clouds grow upward, and they can develop into a giant cumulonimbus, which is a thunderstorm cloud.
13. Cumulonimbus clouds Cumulonimbus clouds are thunderstorm clouds that form if cumulus clouds continue to grow vertically. Their dark bases may be no more than 300 m (1000 ft) above the Earth's surface. Their tops may extend upward to over 12,000 m (39,000 ft). Tremendous amounts of energy are released by the condensation of water vapor within a cumulonimbus. Lightning, thunder, and even violent tornadoes are associated with the cumulonimbus.
