(This may be done in class or by each student at home.) Using adhesive tape and/or rubber bands students are to combine floating and sinking objects so that combination “hovers” in water. Concept is density differences between water and objects control sinking and floating.

; To make and test predictions about sinking and floating. To classify objects according to whether they sink or float. ... As they continue to investigate floating and sinking, they should be building the understanding that objects float because a force equal to the weight of the water they displace buoys them up.

Floating or sinking has to do with the amount of water pushed out of the way. Any boat will sink if you put enough stuff inside it -- just like your experiment showed. Small, heavy things like a marble or a rock cannot float because they cannot push enough water out of the way to be the same as how much they weigh..

Some objects, when placed in water, float, while others sink, and still others neither float nor sink. This is a function of buoyancy. We call objects that float, positively buoyant. Objects that sink are called negatively buoyant.
