The study of Chemistry gives students the opportunity to use skills and process of science to explore and explain the composition and interaction of matter. In the elementary grades, students study the matter and classification of substances using easily observable properties. The basis of Chemistry instruction in the middle grades is to provide opportunities for students to move from concrete to abstract levels of thinking.
Students examine the change of state, solutions, and simple chemical reactions.
The relationship between properties of matter, its structure, and interactions continues as a major study in grades 9-12. Structure of Matter Physical or Chemical Changes Classification of Matter Conservation of Matter and Energy For a detailed description of Bolded and Italicized terms, click here . 4.5.3 identify that matter undergoes physical and chemical changes . 4.8.3 distinguish between chemical and physical changes based on observable properties. 4.5.4 explain that when a new material is made by combining two or more materials, it has properties that are different from the original.
