This lesson plan is about separating mixtures of immiscible liquids. The teacher will demonstrate separating kerosene and water using a separating funnel. Students will observe that the kerosene, being less dense, rises to the top while the water, being more dense, sinks to the bottom. Through this activity and a worksheet, students will learn that immiscible liquid mixtures can be separated based on the density of the liquids, with the denser liquid settling below the less dense one in a separating funnel. The goal is for students to understand how to separate mixtures based on differences in density.
