2003 TEST ITEM POOL

The items in this pool represent the work of many Utah science teachers.  The items are aligned to the 2003 Chemistry Science Core Curriculum.  All right to this pool are the property of the Utah State Office of Education.  Permission is granted to teachers, districts, or state agencies to use these items, provided they are not used in a manner that results in the distribution of items or instructional materials for profit.

The items in this pool will be refined each year.  If you find errors in the pool, we wish to correct them. Please contact us. If you are interested in working with the refinement of this item pool, please contact USOE via email.

STANDARD I: Students will understand that all matter in the universe has a common origin and is made of atoms, which have structure and can be systematically arranged on the periodic table.

Objective 1: Recognize the origin and distribution of elements in the universe.

Objective 2: Relate the structure, behavior, and scale of an atom to the particles that compose it.

Objective 3: Correlate atomic structure and the physical and chemical properties of an element to the position of the element on the periodic table.

STANDARD II: Students will understand the relationship between energy changes in the atom specific to the movement of electrons between energy levels in an atom resulting in the emission or absorption of quantum energy. They will also understand that the emission of high-energy particles results from nuclear changes and that matter can be converted to energy during nuclear reactions.

Objective 1: Evaluate quantum energy changes in the atom in terms of the energy contained in light emissions.

Objective 2: Evaluate how changes in the nucleus of an atom result in emission of radioactivity.

STANDARD III: Students will understand chemical bonding and the relationship of the type of bonding to the chemical and physical properties of substances.

Objective 1: Analyze the relationship between the valence (outermost) electrons of an atom and the type of bond formed between atoms.

Objective 2: Explain that the properties of a compound may be different from those of the elements or compounds from which it is formed.

Objective 3: Relate the properties of simple compounds to the type of bonding, shape of molecules, and intermolecular forces.

STANDARD IV: Students will understand that in chemical reactions matter and energy change forms, but the amounts of matter and energy do not change.

Objective 1: Identify evidence of chemical reactions and demonstrate how chemical equations are used to describe them.

Objective 2: Analyze evidence for the laws of conservation of mass and conservation of energy in chemical reactions.

STANDARD V: Students will understand that many factors influence chemical reactions and some reactions can achieve a state of dynamic equilibrium.

Objective 1: Evaluate factors specific to collisions (e.g., temperature, particle size, concentration, and catalysts) that affect the rate of chemical reaction.

Objective 2: Recognize that certain reactions do not convert all reactants to products, but achieve a state of dynamic equilibrium that can be changed.

STANDARD VI: Students will understand the properties that describe solutions in terms of concentration, solutes, solvents, and the behavior of acids and bases.

Objective 1: Describe factors affecting the process of dissolving and evaluate the effects that changes in concentration have on solutions.

Objective 2: Summarize the quantitative and qualitative effects of colligative properties on a solution when a solute is added.

Objective 3: Differentiate between acids and bases in terms of hydrogen ion concentration.
