  • 1. Clouds
    By Isobelle
  • 2. How clouds are made
    Water droplets float into the sky, they hang in the atmosphere and eventually they find dirt and dust particles to cling to. Then they create a cloud.
    Dirt particles
    Forming cloud
    Water particles
    Water droplets rising up to the cloud
  • 3. Different types of clouds
    Some clouds are white and fluffy, like the ones you see on a sunny day.
    Other clouds are gray and stormy, like the ones you see on a rainy day.
    Clouds can be in all different shapes and sizes, sometimes people can see animals and things in the clouds.
  • 4. Experiment
    In our science class we did an experiment.
    Aim: To create a cloud in a bottle
    We needed...
    a pump bottle and
    Matches.
    1. make sure there is 1 cm of water in the bottle.
    2. light the match and put some smoke in the bottle.
    3. close the lid and squeeze the bottle(really tight) and watch what happens...
  • 5. ...IT MAKES A CLOUD!
    All the particles in the bottle are spread out until the bottle is squeezed. Then all the particles come together and start creating friction the smoke gives them something to cling to like it does when real clouds are made. Then it becomes a cloud.

  • 6. Diagram
    Smoke, water and air particles in bottle
    Bottle with cloud in it (smoke, water and air particles)
    Creating friction gives the particles energy to mix with the dirt particles
    Bottle with pressure being applied
    Bottle before it's squeezed
    Smoke, water and air particles being squeezed together creating friction
  • 7. Clouds
    There are 2 main types of clouds:
    Layard and convective. They are defined by altitude, the base of the cloud.
