Learning outcomes

Students will:

  • Learn what clouds are made of and how they are made.
  • Learn that there are different types of clouds.
  • Learn that water droplets which form on the outside of a cold glass on a hot day are another form of condensation.

Teacher planning

Time required for lesson

3 days

Materials/resources

  • metal pie pan
  • glass jar without lid
  • hot water
  • ice cubes
  • freezer

Technology resources

  • computer with internet access
  • Windows on Science laser disk program (unit on weather)

Pre-activities

  • Students are introduced to the three stages of the water cycle through use of the science textbook or other science resources appropriate for your grade level.
  • Discuss with students why they see clouds some days and do not see clouds on other days.
  • Discuss what happens to a glass filled with a cold drink on a hot day.

Activities

  1. Cloud in a Jar activity
    • Put the metal pie pan in the freezer for about an hour.
    • Fill the jar half full with hot water just before you take the pan out of the freezer.
    • Remove the pan from the freezer and fill it with ice cubes. Set the pan on top of the jar. Leave it there for a few minutes and observe what happens inside the jar.
  2. Fill a glass or jar with ice cubes and water. Let it sit at room temperature. Have students observe and record what happens after one minute, five minutes, and ten minutes.
  3. Complete the Condensation Scavenger Hunt.
  4. Read appropriate books related to the water cycle and condensation.

Assessment

Students will successfully complete the Condensation Scavenger Hunt. Students will respond appropriately to teacher’s questions (PDF) about condensation.
