This is an awesome discrepant event for your most advanced 'density' students! When this solid white object is placed in water, it initially sinks. Wait about 60 seconds, and it mysteriously floats to the surface. When removed and placed in different water, it continues to float initially and, in about 60 seconds, mysteriously sinks. Why? How can this be? Great for demonstrating how temperature can affect an object's density! In the experiment described above, the first beaker contained hot water from the tap; the second beaker contained ice water.

Students try to identify each of 12 different samples by determining their density.

Density Mystery Set

Ask students to determine the density of 12 identical looking, black plastic specimens of various sizes. Results will vary.
