Montessori's Land, Air, & Water lesson is a simple one that requires labels and samples of each. The Air dish appears empty but is filled with what the element we can not see or taste, although we know it is there because it fills our lungs. You may also want a balloon and stick with a ribbon attached. Blow up the balloon and ask your child "What is in the balloon to make it big?" Then you may blow at the ribbon and ask your child "What made the ribbon move?"
