National Standards for Grades 6-9


Ten investigations introduce students to the topics of changes in matter. Acquaint students with classifying matter as elements, mixtures, or compounds, and introduce atomic structure, nomenclature, and the use of symbols to code for chemical elements. Students 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 chemical reactions between solutions resulting 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. Allow two hours to complete all activities. Designed for 24 students working in groups of four. Required, not included: chemical splash goggles.
