Float and Sink

Today in Room 4 we did an experiment to see which objects float and which objects sink.  We tested items like clay, a paperclip, a button, aluminum foil (in a flat sheet and in a rolled-up ball), a popsicle stick, and a button.  The children predicted if an object would float or sink, and then each child got to drop an item in the water to see if our predictions were correct.
