STC Program: Chemical Tests, 2nd Edition
With this unit, students explore the properties of 5 common "mystery" powders. They mix water with the powders and conduct various experiments involving solubility, filtration, evaporation, crystallization. Students test the powders with heat, iodine, and red cabbage juice (a natural pH indicator) and describe the changes.
