Physical Science: Unit 6: Chemical Reactions
Time Frame: 6 weeks—March 24 – May 9, 2014
Unit Description and Student Understandings: Chemical reactions will be classified and related to the Law of Conservation of Matter and balancing
chemical equations. The pH of substances will be investigated using a variety of indicators. Chemical concepts will be applied to students’ personal
environments. Students will observe a number of chemical changes and predict the results of planned laboratory activities and investigations. Students will
identify the signs of a chemical reaction, name chemical compounds from the formula, determine the correct formulas for compounds using information on
elements in the periodic table, classify chemical reactions, balance chemical equations, identify endothermic and exothermic reactions, and measure
temperature and pH changes. Students will learn about the process of dissolving and how to quantify concentration of solutions. Properties of acids, bases, and
indicators will be discussed. Students will also learn about the basic structures, nomenclature, and functional groups of organic chemistry.

Can student recognize the relationship between the mass of the products and the mass of the reactants in a chemical reaction?
Can student describe how stated factors affect rate of dissolving?
Can student differentiate among acid, base, and neutral substances?
Can student determine the pH of substances using indicators and classify the substances as acid, base, or neutral?
Can student relate chemistry to everyday life?
Can students model or interpret diagrams of simple organic compounds?
Key Concepts/Big Idea:
 When atoms form compounds, each atom is more stable in the compound than it was by itself
 Atoms form ionic bonds by transferring electrons and form covalent bonds by sharing electrons
 For both ionic and covalent compounds, you can write a name from the chemical formula or a chemical formula from the name
 A balanced chemical equation describes the rearrangement of atoms in a chemical reaction.
 Reactions can be classified based on how atoms are rearranged
 Exergonic reactions release energy release energy and endergonic reactions absorb energy
 Every chemical reaction proceeds at a definite rate, which can be speeded up or slowed down by changing the conditions of the reaction
 A solution forms when a solute or solutes and a solvent or solvents become evenly mixed.
 In a given amount of solvent, concentration is the amount of solute actually dissolved an d solubility is the maximum amount of solute
that can dissolve.
 Dissolved particles can both lower the freezing point and raise the boiling point of a solvent.

Polarity determines which solvent will dissolve a substance.
Acids produce hydronium ions (H20+) in water, and bases produce hydroxide ions (0H-) in water.
Strength describes the degree to which an acid or base ionizes or dissociates in water; concentration describe the amount of acid or base
dissolved in a certain volume of water.
An acid and a base react to form a salt and water.
Substituted hydrocarbons contain other elements besides carbon and hydrogen.
Proteins, carbohydrates, lipids, and nucleic acids are large, organic molecules made by plants and animals.\
An alloy is a mixture of elements that has metallic properties.
Ceramics and semiconductors have conductivities that can range from highly insulating to superconductive.
A huge variety of human-made products, from plastics to aircraft components, are made from polymers and composites
