SFUSD Chemistry Scope & Sequence Grade 10
Our Storyline In the fall, students will begin with stars, seeing the formation of the first element, and its transformation to heavier elements. They will explore the structure of the atom and patterns on the periodic table. They will analyze the forces that hold elements together and consider how society uses this understanding to develop materials useful to society, before delving into how substances interact with each other. In the spring, students will begin by surveying Earth s climate and the impact of humans. They will then use their understanding of elements and materials science to investigate energy concepts and the factors that drive chemical and physical changes. They will later explore greenhouse gases, their effect on the atmosphere and subsequently how the atmosphere affects the ocean and other bodies of water on Earth. To culminate the spring semester s learnings, students will develop and evaluate possible solutions to global environmental concerns.
Year at a Glance Fall Semester: Unit 0: Lab Safety Spring Semester: Unit 3x: Climate Change and Earth s Systems Unit 1: Stars Unit 2: Material Science Unit 3: Chemical Reactions Unit 4: Energy Unit 5: Atmosphere Unit 6: Water Unit Δ: Applied Science Project
Unit 0: Lab Safety Why Chemistry? What are safe chemical practices?
Unit 1: Stars 3. Where do elements come from? How are elements formed? How are elements different from or similar to each other? Atoms Periodic table and trends Spectra Valence electrons and energy levels Fission and Fusion Radioactive decay and dating Stars as element factories
Unit 2: Material Science 3. What holds matter together? Why do materials have different properties? How /why do we use different materials in society? Bond formation VSEPR Electronegativity and how it determines molecular polarity Intermolecular forces Formation and properties of polymers *Optional: Nomenclature
Unit 3: Chemical Reactions How do chemicals react and change? What are the relationships between materials and energy in a chemical reaction? How molecules interact with each other Chemical reactions The Law of the Conservation of Matter Changes in bond energies in chemical reactions Dimensional analysis Mole concept Chemical energy (ONLY endothermic and exothermic)
Unit 3x: Climate Change and Earth s Systems What is happening to Earth s climate? What are some possible reasons/correlations to it changing? How the climate is changing
Unit 4: Energy 3. What factors drive chemical and physical changes? How does energy and matter flow (rearrange) and change in and between systems? How does transfer of energy drive changes in the Earth s systems over different time scales? Stoichiometry Chemical energy First and Second Laws of Thermodynamics Phase changes Heat and enthalpy Energy and climate change
Unit 5: Atmosphere 3. How do changes in the composition of Earth s atmosphere drive climate change? What influence do humans have on the atmosphere? How can climate change affect us? Atmospheric composition Understanding gases Greenhouse gases Cycling of carbon
Unit 6: Water 3. 4. What influences the outcome and rate of a chemical reaction? How have humans impacted the equilibrium system that is the hydrosphere? How are the chemistry of the oceans and water systems changing and why? How do changes in our oceans affect global climate? Properties of water Solutions and concentration Rates of reactions Equilibrium Acid-base/pH Hydrosphere chemistry (e.g. ocean acidification)
Unit Δ: Applied Science Project In this key experience, students propose a solution to one local or global environmental issue.
