Students from 3rd ESO have made an experiment about solubility. They were divided in three groups and they have investigated three different hypotheses:
1. The amount of sugar dissolved depending on the quantity of solvent.
2. The amount of sugar dissolved depending on the temperature.
3. The amount of sugar dissolved depending on the type of solvent.
When they have finished the experiment, they have prepared an oral exposition to explain what were the results and the conclusions.
