There are 3 crossword puzzles all made with the same clues. This gives the teacher options for use -- different puzzle for each different section of students to prevent passing along answers, use for multiple times or for students who were absent when the puzzle was used.
There is also an Identification Chart of the 40 astronomical object pictures used for questions. Students can look up data they can't remember or don't know.
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.
