45 cards list important concepts from Rocks & Minerals content, including physical properties of matter, rock types and examples, mineral properties and examples, methods for identifying rocks and minerals, and the rock cycle. The cards can be used in a game played against two teams of students or in other ways (as a dismissal game, etc.). When playing in teams of two, one student from a group comes to the front of the room and takes a card. The student tries to get his/her group to guess the word at the top of the card without saying the words underneath. The team gets a certain amount of time and tries to guess as many words as they can. This works great as a boys vs. girls game, or different sides of the room, and is helpful if you ever finish a lesson early and need a review game that can be set up in seconds. The terms are aligned to the New York State Earth Science Regents. These cards are part of a larger set from Michellenbrown Store.
