Innovating Science Solid Mixture Separation Chemistry Kit (Supplies for 15 Groups)

• Hands-on chemistry activity demonstrating concepts of solubility, conservation of mass, and acid-base reactions
• Students will separate two solids from a mixture, then test to ensure that they are chemically distinct
• Practical experience with exploratory chemical techniques
• Includes enough material for fifteen groups of students
• Kit includes teacher's manual, student study guide copymasters, and material safety data sheets for all included materials

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.
