This group of 28 cards gives you science topics such as: WATER CYCLE, EARTH'S ROTATION, FORCES OF EROSION, ETC. Four terms are then given. One does not fit the topic; three do. Students must decide which does not fit and explain why it does not fit. This is a great vocabulary and conceptual review for a year of science instruction. It is also perfect practice for STAAR testing and other end of year testing. There is an answer sheet and an answer key. The students will enjoy these in a whole group setting or in a science center.
