What Is It?
Put something in an opaque bag. Have students sit in a circle and bring the bag around the circle, letting students feel the object without looking at it. After everyone has had a chance to think about what the object might be, list their guesses on the board. In order to eliminate certain guesses, have students list the properties of the object that they were able to ascertain from touching it. Narrow the choices down to those that fit with the descriptions.
