GOBLES, Mich. — Have you ever wanted to make your own lava lamp? Look no further than the salt volcano science experiment! In this week's weather kids experiment, Haleigh Vaughn demonstrates how ...

Students will be able to develop and explain a particle-level model to describe their observations of water dissolving salt, the water evaporating, and the salt crystals re-forming. Dissolving a solid ...

A South Korean research team has experimentally uncovered the principle behind salt dissolution by observing the phenomenon at an atomic level. The Ulsan National Institute of Science and Technology ...

Students will be able to plan and carry out an investigation to compare the solubility of different substances, and develop and explain a particle-level model to describe the process of dissolving.

[Editor's note: In his answer to this question, the late John Margrave argued that salt dissolves in water as ions of sodium and chlorine, and these ions hydrate, or join to, the water molecules. This ...
