CH.1 The student will investigate and understand that experiments in which variables are measured, analyzed, and evaluated, produce observations and verifiable data. Key concepts include * designated laboratory techniques; * safe use of chemicals and equipment; * proper response to emergency situations; * multiple variables are manipulated with repeated trials; * accurate recording, organizing, and analysis of data through repeated trials; * mathematical and procedural error analysis; and * mathematical manipulations (SI units, scientific notation, linear equations, graphing, ratio and proportion, significant digits, dimensional analysis, use of scientific calculator).
This SOL does not have a web site.
CH.2 The student will investigate and understand that the
placement of elements on the periodic table is a function of
their atomic structure. The periodic table is a tool used
for the investigations of
* mass/atomic number;
* isotopes/half-lives/nuclear particles;
* particle/mass charge;
* families/groups;
* series/periods;
* trends/patterns: atomic/nuclear radii, electronegativity,
shielding effect;
* electron configurations/oxidation numbers;
* chemical/physical properties; and
* historical/quantum models.
Allows the user to click on an element and retrieve a list of facts about that element (ie. Atomic weight, atomic number, and density.) Site is a table in html format.
CH.3 The student will investigate and understand how conservation
of energy and matter is expressed in chemical formulas and
balanced equations. Key concepts include
* nomenclature;
* balancing chemical equations;
* writing chemical formulas -- molecular, structural,
empirical, and Lewis diagrams;
* bonding types -- ionic, covalent;
* reaction types -- synthesis, decomposition, single and
double replacement, oxidation-reduction, neutralization,
nuclear, exothermic and endothermic, spontaneous/non-
spontaneous, dissociation ionization;
* physical and chemical equilibrium; and
* reaction rates and kinetics: activation energy,
catalysis, degree of randomness.
A wonderful site that allows you to enter an aspect of the chemical and then gives you a lot of information about that chemical.
CH.4 The student will investigate and understand that quantities
in a chemical reaction are based on molar relationships.
Key concepts include
* avogadro's principle, molar volume;
* stoichiometric relationships;
* partial pressure;
* gas laws;
* solution concentrations;
* chemical equilibrium; and
* acid/base theory: strong/weak electrolytes,
dissociation/ionization (pH, pOH), and titration.
Yue-Ling Wang's Java Interactive Titration Simulation
An interactive site that allows you to perform several different titration simulations. The site graphs the simulation as you enter the data.
CH.5 The student will investigate and understand that the phases
of matter are explained by kinetic theory and forces of
attraction between particles. Key concepts include
* pressure, temperature, and volume;
* vapor pressure;
* partial pressures;
* phase changes;
* molar heats of fusion and vaporization;
* specific heat capacity;
* solutions; and
* colligative properties.
Phases of Matter/Phase Changes
Describes phase changes using real world examples. This site also includes colorful and simple phase diagrams for water.
CH.6 The student will investigate and understand how basic
chemical principles relate to other areas of chemistry. Key
concepts include
* organic and biochemistry;
* nuclear chemistry; and
* environmental chemistry.
A wonderful site that provides links to articles and information related to Biochemistry.
Knowledge by Design- The Learning Matters of Chemistry
