Practise calculating the concentration of a solution from the mass of solute and the volume of water using this lesson plan with activities for 16–18 year olds.

In this activity, students begin by comparing the concentrations of several solutions and reflecting on their current level of understanding. They then work in pairs using cards to link a mass of solute, volume of water and concentration of a solution, exploring the process of calculating concentration.

The lesson plan includes an extension activity giving students additional practise calculating the concentration of solutions.
