Explore trends of physical and chemical properties of elements within periods and groups of the periodic table. The kit includes three experiments for investigating key differences between metals and nonmetals. Students evaluate the luster, density, thermal conductivity, and electrical conductivity of different metals in Experiment 1. Using unknown solutions, students identify the presence of specific metal ions in Experiment 2. In Experiment 3, students observe the properties and reactivity of two nonmetallic elements; chlorine and iodine. 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. Allow 2 hours for experimentation. Designed for 24 students working in groups of four.
