Some suggestions:
For example:When studying the water cycleI took an old already damaged book and put it in the freezeri boiled water on the stoveasking these questions:the water is less in the pan, where is it going? (they were quick to point out, it was becoming steam. So that is evaporation...Then I grab the book out of the freezer and hold it above the steamwater begins to condense...I ask them whats happening etc...then they can answer questions concerning evaporation, condensation, precipitation...without me telling them what to write.
