Students fill in the bingo board template so that each student has a unique board. 40 different Earth science words are included. On the teacher page, the words are defined on cards that you can cut out, so that you can have a student lead the bingo review. The vocabulary words include the following topics: plate tectonics, rocks and minerals, geology, lab materials and safety, and scientific method. You can easily customize the board by omitting words you have not covered yet or adding more to the list.
