Powders and Crystals, Second Edition

Your classroom doubles as a chemistry lab when students must identify six unknown substances that their senses tell them are very similar. First, they view the white particles with pocketscopes and differentiate between the powders and the crystals. After comparing the substances to named samples, students apply several tests to discover the chemical properties of each: the water test, vinegar test, iodine test, BTB test, and heat test. Activity sheets provide detailed instructions for conducting each analysis and recording the results. These test data help students complete the next challenges: deducing the two or three ingredients in four mystery mixtures and exploring three new unknown white particle substances. (12 Activities)
