Play a memory game with science vocabulary words to prepare for an upcoming test! Build  both understanding and retention of new vocabulary words by setting up a matching game for your learners to play in small groups of three to five. Vocabulary words are written on some cards, and definitions are written on the others. The player flips two cards over, and if they match, they take the pair. If they don't, both cards get flipped back over and placed back in their spots. Who will win?
