Generate resourceThe student understands how natural resources are important and can be managed. The student is expected to design and explain solutions such as conservation, recycling, or proper disposal to minimize environmental impact of the use of natural resources.
Generate resourceThe student describes patterns, cycles, systems, and relationships within environments. The student is expected to:
Generate resourceobserve and describe how a variety of organisms survive by interacting with biotic and abiotic factors in a healthy ecosystem;
Generate resourcepredict how changes in the ecosystem affect the cycling of matter and flow of energy in a food web; and

Generate resourceThe student knows that organisms undergo similar life processes and have structures and behaviors that help them survive within their environments. The student is expected to:
Generate resourceanalyze the structures and functions of different species to identify how organisms survive in the same environment; and
Generate resourceexplain how instinctual behavioral traits such as turtle hatchlings returning to the sea and learned behavioral traits such as orcas hunting in packs increase chances of survival.
Generate resourceThe student analyzes and interprets data to derive meaning, identify features and patterns, and discover relationships or correlations to develop evidence-based arguments or evaluate designs. The student is expected to:
Generate resourceidentify advantages and limitations of models such as their size, scale, properties, and materials;
Generate resourceanalyze data by identifying any significant features, patterns, or sources of error;
Generate resourceThe student develops evidence-based explanations and communicates findings, conclusions, and proposed solutions. The student is expected to:
Generate resourcecommunicate explanations and solutions individually and collaboratively in a variety of settings and formats; and
Generate resourcelisten actively to others' explanations to identify relevant evidence and engage respectfully in scientific discussion.
Generate resourceThe student knows the contributions of scientists and recognizes the importance of scientific research and innovation for society. The student is expected to:
Generate resourceexplain how scientific discoveries and innovative solutions to problems impact science and society; and
Generate resourceresearch and explore resources such as museums, libraries, professional organizations, private companies, online platforms, and mentors employed in a science, technology, engineering, and mathematics (STEM) field to investigate STEM careers.
Generate resourceThe student understands that recurring themes and concepts provide a framework for making connections across disciplines. The student is expected to:
Generate resourceidentify and use patterns to explain scientific phenomena or to design solutions;
Generate resourceidentify and investigate cause-and-effect relationships to explain scientific phenomena or analyze problems;
Generate resourceuse scale, proportion, and quantity to describe, compare, or model different systems;
Generate resourceexamine and model the parts of a system and their interdependence in the function of the system;
Generate resourceinvestigate how energy flows and matter cycles through systems and how matter is conserved;
Generate resourceexplain the relationship between the structure and function of objects, organisms, and systems; and
Generate resourceexplain how factors or conditions impact stability and change in objects, organisms, and systems.
Generate resourceThe student knows that matter has measurable physical properties that determine how matter is identified, classified, changed, and used. The student is expected to:
Generate resourcecompare and contrast matter based on measurable, testable, or observable physical properties, including mass, magnetism, relative density (sinking and floating using water as a reference point), physical state (solid, liquid, gas), volume, solubility in water, and the ability to conduct or insulate thermal energy and electric energy;
Generate resourcedemonstrate and explain that some mixtures maintain physical properties of their substances such as iron filings and sand or sand and water;
Generate resourcecompare the properties of substances before and after they are combined into a solution and demonstrate that matter is conserved in solutions; and
Generate resourceillustrate how matter is made up of particles that are too small to be seen such as air in a balloon.
Generate resourceThe student knows the nature of forces and the patterns of their interactions. The student is expected to:
Generate resourceinvestigate and explain how equal and unequal forces acting on an object cause patterns of motion and transfer of energy; and
Generate resourcedesign a simple experimental investigation that tests the effect of force on an object in a system such as a car on a ramp or a balloon rocket on a string.
Generate resourceThe student knows that energy is everywhere and can be observed in cycles, patterns, and systems. The student is expected to:
Generate resourceinvestigate and describe the transformation of energy in systems such as energy in a flashlight battery that changes from chemical energy to electrical energy to light energy;
