This classic demonstration involves conducting flame tests of metal salt solutions. The colour of each flame test can be used as a qualitative test to detect the presence of the corresponding metal salt. Refer back to this demonstration when considering the spectroscopic work done by Neils Bohr and others that led to the ideas of energy levels and the quantization of energy.

This demo models how convection occurs in the atmosphere and hydrosphere by showing what happens at the interface of a hot fluid and a cold fluid. This simulates what happens when cold and hot air... read more
Osmosis is the process by which the concentrations of two solutions, separated by a selectively permeable membrane, equalize by the movement of a solvent such as water. This demonstration shows that... read more
