INVESTIGATION INDICATORS

adminbenscience — Tue, 13 Oct 2026 17:17:10 +0000

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.

CHANGES IN MATTER

adminbenscience — Tue, 13 Oct 2026 17:16:50 +0000

Ten activities acquaint students with classifying matter as elements, mixtures, or compounds and introduce them to atomic structure and nomenclature. Students are introduced to properties of common elements, compounds, and mixtures and learn how symbols are used to code for chemical elements. They separate common mixtures by evaporation and chromatography; proving that mixtures are not chemically combined. They learn that while elements are pure substances made of only one type of matter, compounds are pure substances made up of different chemically combined elements. Students observe that chemical reactions between solutions result in the formation of new compounds with different properties. They learn that color changes, effervescence, formation of solids, and new odors are all indicators that a chemical reaction has occurred. Includes reproducible student instructions, assessment for each activity, vocabulary, and complete answer keys. Required, not included: chemical splash goggles. Designed for 24 students working in groups of four. Meets national standards for Grades 6-9.
