MS. Structure and Properties of Matter Associated Units: Chemical/Physical Properties Heat and Temperature States of Matter Atoms To demonstrate mastery of the Performance Expectation(s) associated with this and related unit modules students will: MS-PS-1 Model, research and describe the atomic composition of elements, molecules and compounds. They will collect and analyze data to identify pure substances by reviewing and comparing physical and chemical properties of the structures. MS-PS1-2, Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. They will organize data and identify patterns about the characteristic physical and chemical of pure substances before and after they interact. Students will analyze the data to identify patterns, including the changes in physical and chemical properties of each substance before and after the interaction. They will support their interpretation of the data by describing that the change in properties of substances is related to the rearrangement of atoms in the reactants and products in a chemical. Students will develop a model in which they identify the relevant components for a given chemical reaction, including the types and number of molecules that make up the reactants and products. MS-PS1-3 Obtain information from published, grade-level appropriate material and determine and describe whether the gathered information is relevant along with the credibility, accuracy, and possible bias of each source. Students will synthesize information and present in various modes (e.g., graphs, diagrams, text, mathematical, verbal to design a system that transfers thermal energy throughout an open and closed system. MS-PS1-4 Gather data and develop text and diagram models that illustrate changes in particle motion and temperature when energy is exchanged in solids, liquids and gases. Models, charts and graphs will show the change in kinetic energy until a change in state occurs. MS-PS-1-6. Undertake a design project to construct test and modify a device that either releases or absorbs thermal energy. Chemical/Physical Properties Unit To demonstrate mastery of the Performance Expectations PS1.A, PS3.A, ETS1.B and ETS1.C, lesson unit may include the following objectives, vocabulary and assessments: Describe how mass and volumes are measured. Measure and compare mass and weight. Measure and calculate density of materials, comparing those of solid, liquid and gas. Understand that density is a characteristic property and does not change with size and shape of material. Measure and calculate density. Use density to identify substances. Demonstrate how density is a derived quantity and how its values are dependent upon accuracy of measurements. Compare density of materials and explain uses of materials based upon the property of density. Infer under what conditions physical and chemical properties may change and measure the effects of temperature and pressure. Identify and define physical and chemical properties of materials as characteristic properties. Measure and compare physical properties under various conditions. Compare and contrast physical and chemical properties. Identify indicators of chemical changes. Demonstrate that in a chemical change new substances are created with different properties. Observe and classify substance changes as physical or chemical.
