Innovating Science® Separation of a Mixture: Physical Properties of Matter
Acids and Bases
After a class discussion of matter and the fact that matter may differ from other matter in a variety of ways, students will examine three different solids individually and observe some differences in physical properties. Sand, iron filings and salt will be observed and tested using water and magnets. Based on what they find individually they will come up with a method (as a class or as groups) to separate a mixture of all three. The activity contains enough materials for 6 groups of students. Kit Includes: 50g Sand 50g Salt 50g iron filings 200g 3 part mixture Magnets Plastic cups Magnifiers
Kit Includes: 30mL 0.01M HCl 30mL 0.01M NaOH 30mL Distilled water 30mL Vinegar 30mL Dilute ammonia 30mL Liquid soap 30mL Lemon juice Neutral litmus paper Spot plates

Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.
