Environment: Water & Air
The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...
Curated OER
Condensation and the Water Cycle
Students explore the natural distallation process that occurs in the water cycle. They use plastic cups and cotton swabs to observe the condensation process that is evident in the water cycle.
