Ask the children to describe what they saw happening in the movie, pictures, or demonstration. Encourage everyone to respond. Older students may want to make a list on board. Introduce the term, Water Cycle . Younger students can use precut pieces and place them on a template or draw their own.
Older students can cut out pieces, or find appropriate magazine pictures to use.
Develop the concept of humidity by spraying the group lightly with the spray bottle. Go back to the water cycle diagram-evaporation step and review how water gets into the atmosphere. Very young children will do this as a class project and make 1 hygrometer for the class or just observe what the teacher does. Older students should be divided into groups and allow to complete the activity within their groups. Keep track of the humidity for 2 weeks.
