Grade Level Expectations
1.1.1: Understand the atomic nature of matter, how it relates to physical and chemical properties and serves as the basis for the structure and use of the periodic table.
1.1.1.c: Describe the properties of electrons, protons, and neutrons (i.e., electrons have negative charge and very little mass, protons have positive charge and much mass, neutrons have neutral charge and the same mass as protons).
1.1.1.d: Explain how changing the number of electrons, neutrons, and protons of an atom affects that atom, including atomic name, number, and placement on the periodic table.
1.1.1.e: Explain the similar properties of elements in a vertical column (groups or families) of the periodic table.
1.1.1.f: Predict the properties of an element based on the element’s location (groups or families) on the periodic table.
1.1.3: Analyze sound waves, water waves, and light waves using wave properties, including frequency and energy. Understand wave interference.
1.1.3.d: Compare the properties of light waves, sound waves, and water waves.
1.1.3.e: Describe the effects of wave interference (constructive and destructive).
1.1.4: Analyze the forms of energy in a system, subsystems, or parts of a system.
1.1.4.a: Explain the forms of energy present in a system (i.e., thermal energy, sound energy, light energy, electrical energy, kinetic energy, potential energy, chemical energy, and nuclear energy).
1.1.4.b: Compare the potential and/or kinetic energy of parts of systems at various locations or times (i.e., kinetic energy is an object’s energy of motion; potential energy is an object’s energy of position).
1.1.4.c: Measure and describe the thermal energy of a system, subsystem, and/or parts of a system in terms of molecular motion (temperature) and energy from a phase change (e.g., observe, measure, and record temperature changes over time while heating ice to boiling water).
1.2.1: Analyze how systems function, including the inputs, outputs, transfers, transformations, and feedback of a system and its subsystems.
1.2.1.a: Explain the interconnections between a system’s parts or subsystems.
1.2.2: Analyze energy transfers and transformations within a system, including energy conservation.
1.2.2.a: Distinguish conditions likely to result in transfers or transformations of energy from one part of a system to another (e.g., a temperature difference may result in the flow of thermal energy from a hot area to a cold area).
1.2.2.b: Describe what happens in terms of energy conservation to a system’s total energy as energy is transferred or transformed (e.g., energy is never “lost,” the sum of kinetic and potential energy remains somewhat constant).
1.2.2.d: Explain how or whether a phase change, a chemical reaction, or a nuclear reaction absorbs or releases energy in a system (e.g., water vapor forming rain or snow releases energy; water molecules speed up as they absorb energy until the molecules gain enough energy to become water vapor).
1.2.3: Understand the structure of atoms, how atoms bond to form molecules, and that molecules form solutions.
1.2.3.c: Describe the structure of atoms in terms of protons and neutrons forming the nucleus, which is surrounded by electrons (e.g., a helium atom usually has a nucleus formed by 2 protons and 2 neutrons, which is surrounded by 2 electrons).
1.2.3.d: Describe how atoms bond to form molecules in terms of transferring and/or sharing electrons (e.g., sodium atoms transfer an electron to chlorine atoms to form salt).
1.2.5: Understand that the Solar System is in a galaxy in a universe composed of an immense number of stars and other celestial bodies.
1.2.5.b: Compare how stars and other celestial bodies (at least 100 billion) are similar and different from each other (i.e., size, composition, distance from the Earth, temperature, age, source of light, and movement in space).
1.2.6: Understand cellular structures, their functions, and how specific genes regulate these functions.
1.2.6.a: Describe cellular structures that allow cells to extract and use energy from food, eliminate wastes, and respond to the environment (e.g., every cell is covered by a membrane that controls what goes into and out of the cell).
1.2.6.c: Describe how genes (DNA segments) provide instructions for assembling protein molecules in cells.
1.2.7: Understand how genetic information (DNA) in the cell is encoded at the molecular level and provides genetic continuity between generations.
1.2.7.a: Describe the role of chromosomes in reproduction (i.e., parents pass on chromosomes, which contain genes, to their offspring).
1.2.7.b: Describe the possible results from mutation in DNA (e.g., only mutations in sex cells can be passed to offspring; mutations in other cells can only be passed to descendant cells).
1.2.7.d: Describe how organisms pass on genetic information via sexual life cycles (i.e., the sorting and the recombination of genes in sexual reproduction results in a great variety of gene combinations and resultant variations in the offspring of any two parents).
1.2.8: Analyze how human organ systems regulate growth, development, and life functions.
1.2.8.a: Name the structural and functional characteristics of human organ systems, including the endocrine, immune, nervous, reproductive, and skin systems.
1.2.8.b: Describe how the human body maintains relatively constant internal conditions (e.g., temperature, acidity, and blood sugar).
1.2.8.c: Explain how human organ systems help maintain human health.
1.2.8.d: Describe the role of human organ systems during human growth and development.
1.3.7: Understand how stars, solar systems, galaxies, and the universe were formed and how these systems continue to evolve.
1.3.7.d: Describe the formation and life cycle of stars.
1.3.7.e: Describe the properties of different stars (e.g., size, temperature, age, formation, energy production).
1.3.9: Analyze the scientific evidence used to develop the theory of biological evolution and the concepts of natural selection, speciation, adaptation, and biological diversity.
1.3.9.a: Describe the factors that drive natural selection (i.e., overproduction of offspring, genetic variability of offspring, finite supply of resources, competition for resources, and differential survival).
1.3.9.b: Explain how natural selection and adaptation lead to organisms well suited for survival in particular environments.
1.3.9.c: Examine or characterize the degree of evolutionary relationship between organisms based on biochemical, genetic, anatomical, or fossil record similarities and differences.
