1 Exploring phenomena or engineering problems

1.1 Asking questions and defining problems
- 1.1.1 Students will be able to ask questions about aspects of the phenomena they observe, the conclusions they draw from their models or scientific investigations, each other's ideas, and the information they read.
  - 9C.1.1.1.1 Ask questions about the impact of greenhouse gases on the Earth's climate by analyzing their molecular structure and responses during energy absorption.
1.2 Planning and carrying out investigations
- 1.2.1 Students will be able to design and conduct investigations in the classroom, laboratory, and/or field to test students' ideas and questions and will organize and collect data to provide evidence to support claims the students make about phenomena.
  - 9C.1.2.1.1 Plan and conduct an investigation to gather evidence to compare the structure of substances and infer the strength of electrical forces between particles.
    - Explore intermolecular forces and kinetic energy in phase diagrams (Ch-N.1)
  - 9C.1.2.1.2 Plan and conduct an investigation of acid-base reactions to test ideas about the concentrations of the hydronium ion in an aqueous solution (pH).
    - The pH scale (Ch-W.)
    - Calculations involving the pH of strong acids and bases (Ch-W.1)

2 Looking at data and empirical evidence to understand phenomena or solve problems

2.1 Analyzing and interpreting data
- 2.1.1 Students will be able to represent observations and data in order to recognize patterns in the data, the meaning of those patterns, and possible relationships between variables.
  - 9C.2.1.1.1 Analyze patterns in air or water quality data to make claims about the causes and severity of a problem and the necessity to remediate or to recommend a treatment process.
2.2 Using mathematics and computational thinking
- 2.2.1 Students will be able to use mathematics to represent physical variables and their relationships, compare mathematical expressions to the real world, and engage in computational thinking as they use or develop algorithms to describe the natural or designed worlds.
  - 9C.2.2.1.1 Develop a data simulation, based on observations and experimental data of how the pressure, volume, temperature, and mass of a gas are related to each other, to predict the effect on a system of changing one of those variables.
    - Boyle's Law: pressure and volume relationships of gases (Ch-S.1)
    - Charles's Law: volume and temperature relationship of gases (Ch-S.)
  - 9C.2.2.1.2 Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.

3 Developing possible explanations of phenomena or designing solutions to engineering problems

3.1 Developing and using models
- 3.1.1 Students will be able to develop, revise, and use models to represent the students' understanding of phenomena or systems as they develop questions, predictions and/or explanations, and communicate ideas to others.

  - 9C.3.1.1.2 Develop a model based on evidence to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
    - Identify exothermic and endothermic processes (Ch-E.1)
  - 9C.3.1.1.3 Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.
    - Classify nuclear reactions (Ch-H.1)
3.2 Constructing explanations and designing solutions
- 3.2.1 Students will be able to apply scientific principles and empirical evidence (primary or secondary) to explain the causes of phenomena or identify weaknesses in explanations developed by the students or others.
  - 9C.3.2.1.1 Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
    - Classify chemical reactions (Ch-Q.1)
    - Single replacement reactions (Ch-Q.)
  - 9C.3.2.1.2 Apply scientific principles and evidence to provide an explanation about the effects of changing the surface area, agitation, temperature, and concentration of the reacting particles on the rate at which the reaction occurs.
    - Factors that affect reaction rate (Ch-U.1)
  - 9C.3.2.1.3 Construct an explanation for the phenomenon of solution creation and identify from patterns how the properties of the resulting solution depend on the interactions between solute and solvent or on concentrations of solutes.
    - Solve problems using solubility curves (Ch-T.1)
