An ideal experiment for the younger grades as an introduction to buoyancy. This experiment is meant to be used during a unit on matter and/or water. Children will have a ball discovering which of the items will float or sink.
Materials need for each group of students are:
clear bowl, water, marble, foil, rubber band, sponge, cotton ball, straw, toothpick, crayon.
Make sure you have towels ready incase of a spill! If you have a water table in your class already, use it for this experiment!
We here at What We Get Up To hope that your children enjoy this experiment as much as we do!
