The So Very Close! Game is almost a science experiment. Kids take different objects, place them in water inside a graduated cylinder, and then they measure how much water each object displaces. It's a good idea to have students work on a surface where if water spills a little it won't hurt anything. Small, somewhat manageable objects work best, and if they're irregularly shaped that makes the guessing and estimating a lot more challenging and a lot more fun!
