Before class, cut out each card and rubber band them together. Next, students sort cards into facts about soil. The soil included is gravel, sand, silt, and clay. The facts include particle size, texture, color, capacity to retain water, and ability to support plant growth.
I print the cards on card stock and use them 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.
