Virtual water is the amount of water that we ignore in water consumption and is considerably higher than the visible water we see in daily uses. Realizing the water spent in the production processes of objects can cause us to change our consumption habits. In 1979, Joseph Cornell presented a four-step framework called Learning Flow to move nature awareness into classes effectively. This study includes a four-step activity designed by Cornell's learning flow design. This activity, small groups work using paper, pencil, and various objects. The prepared activities were applied to different groups like secondary school students, high school students, teacher candidates, and teachers. At the end of the event, personal action steps were determined as individuals know the concepts of "virtual water" and "water footprint". As a result of informal interviews, it has been determined that the effect of the activity continues after four months later.
