The water cycle in a bag

The water cycle in a bag Colegio Concertado Barcelona     The water cycle in a bag Colegio Concertado Barcelona

As part of the social science curriculum, second graders have carried out an experiment in which they could witness evaporation, condensation and precipitation by enclosing water in an airtight bag and leaving it in a warm area.

The learning objectives of this activity were to have students construct a model water cycle; recognize that water changes from one state to another; and learn the stages of the water cycle.
