Middle School Chemistry: The Water Molecule and Dissolving

Middle School Chemistry: The Water Molecule and Dissolving

This set of multimedia lessons, developed by the American Chemical Society, examines the process of dissolving materials in water. Videos, interactive simulations, hands-on labs, and demonstrations are all integrated into a 9-part unit of instruction that includes assessments and background information. Students will explore why water dissolves salt and sugar, conduct solubility tests, investigate how temperature affects dissolving, and more. <i><b>Editor's Note:</b> The authors designed this curriculum to help students understand basic chemistry within a framework of molecular interactions. The molecular models and related animations provide a foundation for understanding states of matter, atomic models and bonding, charge interactions, and chemical change.</i>
