Chemical Tests

Bar Code: 2303


Descprition: Chemical Tests introduces students to thescience of chemistry by challenging them to explore and determine theidentity of five common household chemicals: sugar, alum, bakingsoda, and cornstarch. Students begin by focusing on the physicalproperties of color, form, and texture.Next, they explore chemicalproperties by observing how the five powders interact with water,vinegar, iodine, and red cabbage juice. These tests enable them toexplore phenomena such as crystallization and to observe theprocesses of evaporation and filtration. Finally, students applytheir skills and their knowledge of the five chemicals to identify avariety of "mystery" mixtures. As a result of conducting theseinvestigations, students develop scientific skills such as observingand recording results, forming conclusions on the basis ofexperience, communicating results, and applying their knowledge to solve problems.
