This is the perfect kit for your curious little one. Just add water to the pouch, close it, hang it by a window and let the sun do the rest.  Your little one will learn about the cycles of water from condensation to precipitation from their window.  The kit also contains 3 weather sheets for your little one to track the weather, the season and the temperature, 3 outdoor scavenger hunt sheets you can use during walks, crayons, and 2 hooks to hang the pouch on your window.
