These 3 puzzles have the same clues but different arrangement. This allows the teacher the option to use on multiple dates, different classes, all in one class to prevent cheating or a make-up word for absentees when the puzzle was used in class. There is Resources Chart to help the student with names for clues.
There are many nature study and science games in my TPT store -- Word Search, Crosswords. Anagrams, Bingo, Rummy, Concentration, Sorting, Tic Tac Know, Dominoes and Board games.
