There are 3 different crossword puzzles using the same clues. This enables a teacher to use them multiple times or to prevent "copying" or for absent students. There are 36 questions about the 8 phases of the moon. There is also an Identification Chart showing all the data needed so students can look up difficult clues.
There are many nature study and science games in my TPT store -- Word Serarch, Crosswords, Anagrams, Bingo, Rummy, Concentration, Sorting, Tic Tac Know, Dominodes and Board games.
