Sink, Float, & Density

We have been investigating the concept of Density in class the past week  We have studied Buoyant Force using tanks of water, fishing bobbers, assorted materials that sink and float, and we have tested aluminum foil boats to see how many marbles they can hold before they sink.
We also eplored the relationship between the volume of water and it's mass.
