In this water cycle science lab experiment, students create a terrarium in a plastic bottle and place it in a warm, sunny spot to observe the stages of the water cycle: evaporation and transpiration, condensation, precipitation, runoff and collection. They'll add soil, a pond, and a plant to create a mini model of how Earth cycles its water. This resource includes:teacher directions, discussion questions, and extension activitiesbackground information about the water cycle and how it worksstep b
