Investigating Indicators

Target Grades: 4-8

Dramatic color changes and kitchen chemistry make this kit ideal for attracting elementary scientists. Utilizing the investigative and experimental "what if" approach, students predict, observe, and analyze using common household items they recognize. First they test for acids using natural indicator solutions from red cabbage and black bean juice, then they are introduced to the terms acid and base as they learn to use blue and red litmus papers. Finally, the students compare the natural indicator system to Universal Indicator pH paper and use color charts; then they make their own Universal Indicator Test Strips from Universal Indicator Solution and filter paper. Using gelatin and a choice of indicator solutions, students make a solid gelled indicator product for testing acids and bases. Includes directions for the isolation and characterization of compounds which act as indicators. Designed for 24 students working in six groups of four. Meets national standards for grades 5-8.
