MATTER VISUAL ORGANIZER   Element Compound Mixture Solution Are the parts identical or different? identical different Chemically or physically combined? Chemically (simplest) Chemically Physically Are the components in fixed amounts or any amounts? Fixed amounts Any amounts How do the properties of the end product differ from the properties of the parts that make it up? Begin = end Begin ≠ end Each keeps its own identity Three Examples Iron, copper, mercury Water, table salt, DNA Soil, sea water, cereal, pizza Coffee, tea, kool-aid MATTER VISUAL ORGANIZER
