Kemtec Science: Periodic Table I Target Grades: 7-12 Number of Students: 24 students working in six groups of four. Through a series of experiments, students are introduced to the arrangement of the periodic table, the characteristics of the elements in different periods and groups of the table, and the key differences between metals and nonmetals. Students evaluate the luster, density, and thermal and electrical conductivity of a variety of metals, then investigate physical and chemical properties of metals and nonmetals. Students test the bleaching ability of chlorine and iodine and test for the presence of starch. Includes all materials required for experiments, vocabulary worksheets, experiment worksheets, reproducible laboratory procedures, a crossword puzzle, a test, a research project on historical aspects of the periodic table, and answer keys.
