Diagram the flow of energy within trophic levels and describe how the available energy decreases in successive trophic levels in energy pyramids.
Describe how gravity governs motion within Earth's solar system.
Describe the structure of atoms and ions, including the masses, electrical charges, and locations of protons and neutrons in the nucleus and electrons in the electron cloud.
Describe the life cycle of stars and compare and classify stars using the HertzsprungRussell diagram.
Describe how primary and secondary ecological succession affect populations and species diversity after ecosystems are disrupted by natural events or human activity.
Calculate the net force on an object in a horizontal or vertical direction using diagrams and determine if the forces are balanced or unbalanced.
The student understands the causes and effects of plate tectonics.
Investigate how mass is conserved in chemical reactions and relate conservation of mass to the rearrangement of atoms using chemical equations, including photosynthesis.
Identify and compare the basic characteristics of organisms, including prokaryotic and eukaryotic, unicellular and multicellular, and autotrophic and heterotrophic.
Identify elements on the periodic table as metals, nonmetals, metalloids, and rare Earth elements based on their physical properties and importance to modern life.
Investigate how organisms and populations in an ecosystem depend on and may compete for biotic factors such as food and abiotic factors such as availability of light and water, range of temperatures, or soil composition.
Explain the development of the Periodic Table over time using evidence such as chemical and physical properties.
Compare and contrast gravitational, elastic, and chemical potential energies with kinetic energy.
Identify and model the main functions of the systems of the human organism, including the circulatory, respiratory, skeletal, muscular, digestive, urinary, reproductive, integumentary, nervous, immune, and endocrine systems.
Investigate and describe how Newton's three laws of motion act simultaneously within systems such as in vehicle restraints, sports activities, amusement park rides, Earth's tectonic activities, and rocket launches.
Compare and contrast elements and compounds in terms of atoms and molecules, chemical symbols, and chemical formulas.
Identify global patterns of atmospheric movement and how they influence local weather.
Explain the use of electromagnetic waves in applications such as radiation therapy, wireless technologies, fiber optics, microwaves, ultraviolet sterilization, astronomical observations, and X-rays.
Compare the density of substances relative to various fluids.
Explain how disruptions such as population changes, natural disasters, and human intervention impact the transfer of energy in food webs in ecosystems.
The student recognizes patterns among the Sun, Earth, and Moon system and their effects. The student is expected to demonstrate that Earth rotates on its axis once approximately every 24 hours and explain how that causes the day/night cycle and the appearance of the Sun moving across the sky, resulting in changes in shadow positions and shapes.
Calculate average speed using distance and time measurements from investigations.
Describe how energy is conserved through transfers and transformations in systems such as electrical circuits, food webs, amusement park rides, or photosynthesis.
Model and illustrate how the tilted Earth revolves around the Sun, causing changes in seasons.
Use the periodic table to identify the atoms and the number of each kind within a chemical formula.
Analyze the beneficial and harmful influences of human activity on groundwater and surface water in a watershed.
Measure, record, and interpret an object's motion using distance-time graphs.
Distinguish between physical and chemical changes in matter.
