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.

Periodic Table of Elements

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.

Chemfinder Searching

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.
