Sadie the water droplet explains the water cycle to 8th grade students in 3 sentences: The water cycle involves Sadie falling as precipitation from clouds, infiltrating into the ground or flowing into bodies of water, evaporating from land or being transpired by plants back into the air, and forming clouds to restart the cycle as she travels the world. Sadie enjoys sliding down mountains as runoff, talking to worm friends underground, being absorbed by her favorite tree Salem, and sleeping in clouds until being dropped again as rain.
