Unit Name: Mixtures and Solutions Topic/Sub-Unit: Separating Mixtures Which Standards are students learning in this unit? Standard 2.2.A Most materials are physical mixtures. Physical mixtures can be composed of different kinds of materials, each having distinct physical properties. These physical property differences can be used to separate, sort, and group the materials of the mixture. (Essential) Standard 2.2.B Mixtures can consist of different combinations of solids and/or liquids. (Essential) Standard 2.2.C Physical properties can be used to separate mixtures through techniques such as filtration and evaporation. (Essential) Standard 2.2.D When a solid is dissolved in a liquid, a solution is formed that can be separated through the process of evaporation. (Essential) Standard 2.3.A The mass of an object remains unchanged when broken into parts. The sum of the parts equals the whole. (Essential) By the end of this unit, students will be able to… Know: A mixture is composed of two or more materials each with their own physical properties. Mixtures can be separated by the use of appropriate tools and processes. The mass of a mixture is the sum of its parts. Vocabulary: Mixture Solution Evaporation Filtration Understand: Do: The properties of a mixture allow it to be separated into its individual components. Use a screen, filter, and the process of evaporation to separate mixtures and compare the mass of a mixture to the mass of its parts. Demonstrate how a mixture can be separated based on the physical properties of its components. Mass
