1.a. Objects can be described in terms of the materials they are made of (clay, cloth, paper, etc.) and their physical properties (color, size, shape, weight, texture, flexibility, attraction to magnets, floating and sinking, etc.).||CA Science||Grade Kindergarten||01. Physical Science||1. Properties of materials can be observed, measured and predicted.|||1.f. Differences in chemical and physical properties of substances are used to separate mixtures and identify compounds.||CA Science||Grade 5||01. Physical Sciences||1. Elements and their combinations account for all the varied types of matter in the world.|||1.g. Properties of solid, liquid, and gaseous substances, such as sugar (C6H12O6), water (H2O), helium (He), oxygen (O2), nitrogen (N2), and carbon dioxide (CO2).||CA Science||Grade 5||01.
