Using their knowledge of the principles of solubility, students will separate two solids in a mixture. Though the two materials being separated look similar, they are chemically distinct. A qualitative test will be performed to assess whether the remaing solutions are completely separated. Students will record their observations and explore different chemical concepts such as conservation of mass, acid-base reactions, and intermolecular forces. Aligns to Next Generation Science Standards MS-PS1-1, -2, and -5, as well as HS-PS1-2, -3, and -7, and explores cross cutting concepts such as scale, proportion and quantity, energy, and matter. In addition to the chemical within the kit, included are a teacher's guide, student study guide copymasters, and material safety data sheets (MSDS) for instructional and storage advice.
