Cloud

Summary: 
Make a cloud in a bottle
Science content (2016 curriculum): 
Chemistry: States of Matter, Properties of Materials (K-7)
Earth/Space: Weather, Seasons, Climate Change (K, 1, 4, 7)
Science topic (2005 curriculum connection): 
Earth and Space Science: Weather (grade 4)
Resource: 
Materials: 
  • Large wide-necked jar
  • Warm water (not hot)
  • Black paper
  • Tape
  • Ice cubes in a plastic bag
  • Matches (not a lighter)
Procedure: 

Tape the black paper to the back of the jar to create a dark background. This will make the cloud more visible.
Fill a third of the jar with warm water. If condensation forms on the inside of the jar, tip it up to clear it off with the water.
Light a match, blow it out, wait for a second or two, then drop the smoking match into the jar.
Quickly put the bag of ice on top of the jar, so it forms a cold lid over the opening.
Water vapour rising from the warm water condenses onto the smoke particles, and is visible as swirling clouds.
Lifting the ice bag releases the cloud.
