5.1.12.D.2. Represent ideas using literal representations, such as graphs, tables, journals, concept maps, and diagrams.
NJ.5.2.12. Physical Science: Physical science principles, including fundamental ideas about matter, energy, and motion, are powerful conceptual tools for making sense of phenomena in physical, living, and Earth systems science.
5.2.12.A. Properties of Matter: All objects and substances in the natural world are composed of matter. Matter has two fundamental properties: matter takes up space, and matter has inertia.
Differences in the physical properties of solids, liquids, and gases are explained by the ways in which the atoms, ions, or molecules of the substances are arranged, and by the strength of the forces of attraction between the atoms, ions, or molecules.
5.2.12.A.2. Account for the differences in the physical properties of solids, liquids, and gases.
Electrons, protons, and neutrons are parts of the atom and have measurable properties, including mass and, in the case of protons and electrons, charge. The nuclei of atoms are composed of protons and neutrons. A kind of force that is only evident at nuclear distances holds the particles of the nucleus together against the electrical repulsion between the protons.
5.2.12.A.1. Use atomic models to predict the behaviors of atoms in interactions.
In a neutral atom, the positively charged nucleus is surrounded by the same number of negatively charged electrons. Atoms of an element whose nuclei have different numbers of neutrons are called isotopes.

5.2.12.A.3. Predict the placement of unknown elements on the Periodic Table based on their physical and chemical properties.
Solids, liquids, and gases may dissolve to form solutions. When combining a solute and solvent to prepare a solution, exceeding a particular concentration of solute will lead to precipitation of the solute from the solution.

5.2.12.B.3. Balance chemical equations by applying the law of conservation of mass.
5.2.12.C. Forms of Energy: Knowing the characteristics of familiar forms of energy, including potential and kinetic energy, is useful in coming to the understanding that, for the most part, the natural world can be explained and is predictable.
Gas particles move independently and are far apart relative to each other. The behavior of gases can be explained by the kinetic molecular theory. The kinetic molecular theory can be used to explain the relationship between pressure and volume, volume and temperature, pressure and temperature, and the number of particles in a gas sample. There is a natural tendency for a system to move in the direction of disorder or entropy.
5.2.12.C.1. Use the kinetic molecular theory to describe and explain the properties of solids, liquids, and gases.
Heating increases the energy of the atoms composing elements and the molecules or ions composing compounds. As the kinetic energy of the atoms, molecules, or ions increases, the temperature of the matter increases. Heating a pure solid increases the vibrational energy of its atoms, molecules, or ions. When the vibrational energy of the molecules of a pure substance becomes great enough, the solid melts.
5.2.12.C.2. Account for any trends in the melting points and boiling points of various compounds.
5.2.12.D. Energy Transfer and Conservation: The conservation of energy can be demonstrated by keeping track of familiar forms of energy as they are transferred from one object to another.
Chemical equilibrium is a dynamic process that is significant in many systems, including biological, ecological, environmental, and geological systems. Chemical reactions occur at different rates. Factors such as temperature, mixing, concentration, particle size, and surface area affect the rates of chemical reactions.

5.2.12.E. Forces and Motion: It takes energy to change the motion of objects. The energy change is understood in terms of forces.
Objects undergo different kinds of motion (translational, rotational, and vibrational).
5.2.12.E.2. Compare the translational and rotational motions of a thrown object and potential applications of this understanding.
The magnitude of acceleration of an object depends directly on the strength of the net force, and inversely on the mass of the object. This relationship (a=Fnet/m) is independent of the nature of the force.
5.2.12.E.4. Measure and describe the relationship between the force acting on an object and the resulting acceleration.
The motion of an object can be described by its position and velocity as functions of time and by its average speed and average acceleration during intervals of time.
5.2.12.E.1. Compare the calculated and measured speed, average speed, and acceleration of an object in motion, and account for differences that may exist between calculated and measured values.

5.3.12.D. Heredity and Reproduction: Organisms reproduce, develop, and have predictable life cycles. Organisms contain genetic information that influences their traits, and they pass this on to their offspring during reproduction.
Genes are segments of DNA molecules located in the chromosome of each cell. DNA molecules contain information that determines a sequence of amino acids, which result in specific proteins.
5.3.12.D.1. Explain the value and potential applications of genome projects.
Inserting, deleting, or substituting DNA segments can alter the genetic code. An altered gene may be passed on to every cell that develops from it. The resulting features may help, harm, or have little or no effect on the offspring’s success in its environment.

5.4.12.A. Objects in the Universe: Our universe has been expanding and evolving for 13.7 billion years under the influence of gravitational and nuclear forces.

5.4.12.F. Climate and Weather: Earth's weather and climate systems are the result of complex interactions between land, ocean, ice, and atmosphere.
Climate is determined by energy transfer from the Sun at and near Earth’s surface. This energy transfer is influenced by dynamic processes, such as cloud cover and Earth’s rotation, as well as static conditions, such as proximity to mountain ranges and the ocean. Human activities, such as the burning of fossil fuels, also affect the global climate.
5.4.12.F.2. Explain how the climate in regions throughout the world is affected by seasonal weather patterns, as well as other factors, such as the addition of greenhouse gases to the atmosphere and proximity to mountain ranges and to the ocean.
Earth’s radiation budget varies globally, but is balanced. Earth’s hydrologic cycle is complex and varies globally, regionally, and locally.
5.4.12.F.3. Explain variations in the global energy budget and hydrologic cycle at the local, regional, and global scales.
Global climate differences result from the uneven heating of Earth’s surface by the Sun. Seasonal climate variations are due to the tilt of Earth’s axis with respect to the plane of Earth’s nearly circular orbit around the Sun.
5.4.12.F.1. Explain that it is warmer in summer and colder in winter for people in New Jersey because the intensity of sunlight is greater and the days are longer in summer than in winter. Connect these seasonal changes in sunlight to the tilt of Earth's axis with respect to the plane of its orbit around the Sun.
5.4.12.G. Biogeochemical Cycles: The biogeochemical cycles in the Earth systems include the flow of microscopic and macroscopic resources from one reservoir in the hydrosphere, geosphere, atmosphere, or biosphere to another, are driven by Earth's internal and external sources of energy, and are impacted by human activity.
