implications of the use of science and its application in solving a specific problem or issue.
PS 2
Effectively communicate scientific ideas, theories, findings and arguments in science using different
communication modes, including verbal (oral, written) and visual (graphic, symbolic), and appropriate formats
(laboratory reports, essays, and multimedia presentations).
LT 1 Use scientific language correctly.
LT 2 Use appropriate communication modes and formats.
LT 3 Acknowledge the work of others and the sources of information used by appropriately documenting
them using a recognized referencing system.
PS 3
Apply scientific knowledge to construct scientific explanations, solve problems, and formulate scientifically
supported arguments.
LT 1 Recall scientific knowledge and use scientific understanding to construct scientific explanations.
LT 2 Apply scientific knowledge and understanding to solve problems set in familiar and unfamiliar
situations.
LT 3 Critically analyze and evaluate information to make judgments supported by scientific understanding.
PS 4
Design and carry out scientific investigations independently.
LT 1 State a focused problem or research question to be tested by a scientific investigation.
LT 2 Formulate a testable hypothesis and explain it using scientific reasoning.
LT 3 Design and carry out scientific investigations that include variables and controls, material and/or
equipment needed, a method to be followed, and the way in which the data is to be collected and
processed.
PS 5
Develop analytical thinking skills to evaluate the method and explain possible improvements.
LT 1 Evaluate the validity and reliability of the method.
LT 2 Judge the validity of the hypothesis (accept/reject) based on the outcome of the investigation.
LT 3 Suggest improvements to the method or further inquiry, when relevant.
PS 6

PS 8
Atoms are composed of protons, neutrons, and electrons. Protons have a positive charge, electrons are negative
in charge, and neutrons have no net charge. Atoms of the same element have the same number of protons. The
number of neutrons in the nucleus of an atom determines the isotope of the element. The properties of materials
are determined by the arrangement and properties of the atoms that compose them.
LT 1 Draw, label and describe the relative charge, mass, and location of the protons, electrons and neutrons in
an atom of an element (e.g., Bohr Model, electron configuration, energy levels).
LT 2 Predict the chemical properties of atoms with known number and arrangement of electrons (valence
electrons).
LT 3 Draw and label a model of an isotope's atomic structure (number of protons, neutrons and electrons)
given the atomic number and atomic mass number of the isotope.
PS 9
When elements are listed in order according to the number of protons, repeating patterns of physical and
chemical properties identify families of elements with similar properties. This Periodic Table is a consequence
of the repeating pattern of outermost electrons.
LT 1 Predict the properties of elements in the periodic table, based on their position in a group and period.
LT 2 Predict periodic table trends (e.g., electronegativity, reactivity, electron affinity, atomic radius, ionic
radius).
PS 10
Ions are produced when atoms or molecules lose or gain electrons, thereby gaining a positive or negative
electrical charge. Molecular compounds are composed of two or more elements bonded together in a fixed
proportion by sharing electrons between atoms, forming covalent bonds.
LT 1 Explain how ions and ionic bonds are formed.
LT2
Diagram covalently bonded molecules (e.g., Lewis dot structures, dot and cross, structural formulas).
LT 3 Distinguish among ionic, molecular, and metallic substances, given their properties.
LT 4 Predict the chemical formula of ionic and covalent compounds based on proportions of ions and atoms.
PS 11
Chemical Reactions change the arrangement of atoms in the molecules of substances. Chemical reactions
release or acquire energy from their surroundings and result in the formation of new substances.
LT 1 Name and describe 5 types of chemical reactions.
LT 2 Write a balanced chemical equation.
LT 3 Predict the products of the five general types of reactions.
PS 12
Solutions are mixtures in which particles of one substance are evenly distributed through another substance.
Liquids are limited in the amount of dissolved solid or gas that they can contain. Aqueous solutions can be
described by relative quantities of the dissolved substances and acidity or alkalinity (pH).
LT 1 Provide examples of common solutions.
LT 2 Compare and contrast the differences in the following processes: dissolving, melting, and reacting.
LT 3 Predict how the pH of a solution is influenced by the addition of hydrogen and or hydroxide ions in an
aqueous solution.
LT 4 Predict how the concentration of a solution is influenced by the addition of a substance.
PS 13
Use the mole in describing chemical quantities by count, mass and volume.
LT 1 Define Avogadro’s number as it relates to a mole of a substance.
LT 2 Describe how to convert the mass of a substance to the number of moles of a substance, and moles to
mass.
LT 3 Identify the volume of a quantity of gas at STP.
PS 14
Use stoichiometry to predict quantities in chemical reactions.
LT 1 Use a balanced equation to predict the quantities of reactants and products that are required or produced
