Grade 6 Science studies solubility

The sixth graders conducted an investigation into the different factors affecting the solubility. Their task was to check what are the factors that affect the time taken to dissolve Alka-seltzer indigestion tablets.

Some of the investigation factors chosen by them are water temperature, the quantity of water, the physical size of the tablet and amount of stirring. They timed how fast the tablet gets dissolved in different scenarios. They concluded their investigation by researching the science behind each of these factors’ effect on the solubility of the tablet.
