Year 5 - Super Solutions
Date: 16th Nov 2023 @ 4:00pm
This week pupils in year 5 conducted an experiment to find out which solids would make a solution when mixed with water. Solids that dissolve into a liquid are known as soluble. Solids that do not dissolve are called insoluble. Salt and sugar were soluble, whereas sand and soil were insoluble. A liquid can only hold so much of a soluble material, as all of the gaps between the particles are filled. Increasing the temperature allows the solute (liquid) to hold more.
