Will It Float or Will It Sink Experiment?
Gather a whole bunch of common objects from around your home or yard and perform the Float or Sink Experiment with your little ones. In this experiment, children can make predictions about whether or not an item will sink or float when placed into water.
When an object sinks, it goes down with gravity, and when an object floats, it can stay up by itself. Weight is one factor in sinking and floating, but it is not the cause. This experiment demonstrates how items of different densities will float or sink. Young children may not be ready to understand why objects sink and why they float, but they can make hypotheses and observe what happens when they are dropped into water.
Some children may think an object sinks or floats because an object is heavy or light. But not all heavy objects sink, and not all light objects float. For example, large ships are very heavy but they float. Also, a pound of feathers will float and a pound of bricks will sink.
