In this lesson, we are going to introduce the students to the idea of solubility. We are going to explore the topic starting from daily examples such as how do you clean oil or salt. Then introduce the idea of dissolve, the definition of solute and solvent to the students. Furthermore, we are going to talk briefly about the molecular principles behind different material's dissolving. The lesson is composed of four experiments: 1. What does it mean to dissolve? 2. Solubility of liquids; 3. Solubility of solids into liquids; 4. How do you wash oil from your hands?
