Forming a Precipitate

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity, scholars observe the process. The lesson also focuses on the concept of conservation of mass with the analysis questions.
