In this activity, students will sort cards into reflect, refract, transmit, and absorb definitions, diagrams, and examples.
Before class print the cards on card stock, cut them out, and rubber band the sets together. I keep the sets to reuse over and over. I often use this activity as a warm up or review at the beginning of class. I keep several answer keys, so students that finish quickly become expert checkers. With the help of student checkers, this activity can easily be finished in five minutes for the whole group. I also pull these cards out right before our state standardized test. They are a great review for topics we study at the beginning of the year.
