2011 8th Grade Science Curriculum Guide-Alleghany County Schools X 1st-6 weeks 2nd -6 weeks 3rd-6 weeks 8th Grade Science Essential Standard: Science as Inquiry 8.P.1 Understand the properties of matter and changes that occur when matter interacts in an open and closed container. Clarifying Objective: 1.1 Classify matter as elements, compounds, or mixtures based on how the atoms are packed together in arrangements. 1.2 Explain how the physical properties of elements and their reactivity have been used to produce the current model of the Periodic Table of elements. 1.3 Compare physical changes such as size, shape and state to chemical changes that are the result of a chemical reaction to include changes in temperature, color, formation of a gas or precipitate. 1.4 Explain how the idea of atoms and a balanced chemical equation support the law of conservation of mass Unpacking: What does this standard mean a student should know, understand, and be able to do? 1.1 Atoms- arrangement, elements, mixtures and compounds 1 2011 8th Grade Science Curriculum Guide-Alleghany County Schools 1.2 Periodic Table- arrangement, reactivity, periods/groups, metals, non-metals and metalloids, conductivity 1.3 Physical and Chemical Properties-states of matter, chemical formulas and reactions 1.4 Law of Conservation of Mass- Chemical Equations Essential Questions: What are you made of? If you can’t see an atom, how do we know it is there? What evidence proves whether you have a physical or chemical change? What are the risks/benefits of chemicals on the human health condition? How is the Law of Conservation of Matter relevant to everyday life? Essential Vocabulary: Atom, molecule, compounds, chemical/physical change, mixtures (heterogeneous and homogenous), Mendeleev, metals, non-metals, metalloids, reactivity, conductivity, periods, groups, melting/boiling point, specific heat, pH, density, solubility, polarity, solid, liquid and gas, precipitate, chemical formulas, Law of Conservation of Matter Learning Targets: “I Can” I can explain the relationships between atoms and elements. (R) Identify Student Success: "I Will" • I will compare and contrast atoms verses elements I can explain how elements combine to form compounds. (R) • I will recognize elements by capitalized/upper case chemical symbol and identify compounds as two or 2 2011 8th Grade Science Curriculum Guide-Alleghany County Schools I can differentiate mixtures from compounds. (R) more elements written together. • I will determine the numbers of atoms in a given molecule or Compound I will compare and contrast mixtures and compounds. • I will explain the difference between homogeneous and heterogeneous mixtures. • I will recognize a homogeneous mixture is a solution I can explain how the Periodic Table is organized. (r) I will explain how groups and periods are arranged on the Periodic Table and identify the patterns evident in the elements. • I will interpret chemical reactivity of elements based on their grouping on the Periodic Table. • I will identify metals, nonmetals, and metalloids on the Periodic Table I can compare physical and chemical changes of matter. (R) I will identify characteristics of physical changes to include: appearance, texture, color, odor, melting/boiling points, density, solubility, polarity. • I will analyze changes in states of matter to recognize them as physical changes. • I will identify characterisitics of chemical changes to include: gas production , precipitate formation and 3 2011 8th Grade Science Curriculum Guide-Alleghany County Schools change in color or heat. I can understand that all physical and chemical changes involve a change in energy. I will list examples of energy changes that are both chemical and physical I can explain how the idea of atoms and a balanced chemical equation support the Law of Conservation of Mass. I will examine how the mass of products always equals the mass of reactants in a closed system and in an open system it will not hold true. • I will count atoms to evaluate and confirm that mass is neither gained or lost in chemical reactions Resources: Eric Loveday’s File Cabinet for 8th Grade NC Science ( PowerPoints, Labs, Notes, etc.) https://sites.google.com/a/thelovedays.com/eric-loveday/files Chemistry lessons, activities, worksheets, etc. www.sciencespot.net Lab Activities, Lessons, Demonstration Ideas, etc. www.middleschoolscience.com Videos www.unitedstreaming.com Online Equation Balancer http://education.jlab.org/elementbalancing/index.html BrainPoP Fireworks- http://www.brainpop.com/technology/funtech/fireworks/preview.weml Atom Builder Activity http://www.pbs.org/wgbh/aso/tryit/atom/ Extensions (for students who achieve the goals initially): Study Island Virtual Labs Team Teaching Activities and Strategies Research/Presentations on Periodic Table/Elements Element Games http://education.jlab.org/indexpages/elementgames.php Element Quiz http://funbasedlearning.com/chemistry/elemQuiz/default.htm 4 2011 8th Grade Science Curriculum Guide-Alleghany County Schools Periodic Table Game http://www.rsc.org/Education/Teachers/Resources/ptdata/games/findelement.htm Chemistry Challenge http://www.quia.com/cb/3333.
