Identify an instance from the history of science in which scientific knowledge has changed when new evidence or new interpretations are encountered.
N.2.1
Nature of Science Logo. Includes a microscope symbol on a yellow background.
Distinguish between an experiment (which must involve the identification and control of variables) and other forms of scientific investigation and explain that not all scientific knowledge is derived from experimentation.
N.1.3
Nature of Science Logo. Includes a microscope symbol on a yellow background.
Explain that empirical evidence is the cumulative body of observations of a natural phenomenon on which scientific explanations are based.
N.1.6
Nature of Science Logo. Includes a microscope symbol on a yellow background.
Recognize and explain the difference between theories and laws and give several examples of scientific theories and the evidence that supports them.
N.3.1
EEarth and Space Science
EEarth and Space Science
Symbol for solar system in grey on a blue background.
Describe the layers of the solid Earth, including the lithosphere, the hot convecting mantle, and the dense metallic liquid and solid cores.
E.6.1
Symbol for solar system in grey on a blue background.
Explain and give examples of how physical evidence supports scientific theories that Earth has evolved over geologic time due to natural processes.
E.6.4
Symbol for solar system in grey on a blue background.
Recognize that heat flow and movement of material within Earth causes earthquakes and volcanic eruptions, and creates mountains and ocean basins.
E.6.7
Symbol for solar system in grey on a blue background.
Identify the patterns within the rock cycle and relate them to surface events (weathering and erosion) and sub-surface events (plate tectonics and mountain building).
E.6.2
Symbol for solar system in grey on a blue background.
Explore the scientific theory of plate tectonics by describing how the movement of Earth's crustal plates causes both slow and rapid changes in Earth's surface, including volcanic eruptions, earthquakes, and mountain building.
E.6.5
Symbol for solar system in grey on a blue background.
Identify current methods for measuring the age of Earth and its parts, including the law of superposition and radioactive dating.
E.6.3
Symbol for solar system in grey on a blue background.
Identify the impact that humans have had on Earth, such as deforestation, urbanization, desertification, erosion, air and water quality, changing the flow of water.
E.6.6
LLife Science
LLife Science
Life Science Logo. Includes a DNA symbol on a green background.
Recognize that fossil evidence is consistent with the scientific theory of evolution that living things evolved from earlier species.
L.15.1
Life Science Logo. Includes a DNA symbol on a green background.
Understand and explain that every organism requires a set of instructions that specifies its traits, that this hereditary information (DNA) contains genes located in the chromosomes of each cell, and that heredity is the passage of these instructions from one generation to another.

L.17.3
Life Science Logo. Includes a DNA symbol on a green background.
Explore the scientific theory of evolution by recognizing and explaining ways in which genetic variation and environmental factors contribute to evolution by natural selection and diversity of organisms.
L.15.2
Life Science Logo. Includes a DNA symbol on a green background.
Compare and contrast the relationships among organisms such as mutualism, predation, parasitism, competition, and commensalism.

Life Science Logo. Includes a DNA symbol on a green background.
Explain and illustrate the roles of and relationships among producers, consumers, and decomposers in the process of energy transfer in a food web.
L.17.1
Life Science Logo. Includes a DNA symbol on a green background.
Explore the scientific theory of evolution by relating how the inability of a species to adapt within a changing environment may contribute to the extinction of that species.
L.15.3
Life Science Logo. Includes a DNA symbol on a green background.
Compare and contrast the general processes of sexual reproduction requiring meiosis and asexual reproduction requiring mitosis.
L.16.3
