7.SA1.1

asking questions, predicting, observing, describing, measuring, classifying, making generalizations, inferring, and communicating*

7.SA1.2

collaborating to design and conduct simple repeatable investigations, in order to record, analyze The student demonstrates an understanding of the processes of science by [8] SA1.1 asking questions, predicting, observing, describing, measuring, classifying, making generalizations, inferring, and communicating* [8] SA1.2 collaborating to design and conduct repeatable investigations, in order to record, analyze (i.e., range, (i.e., range, mean, median, mode), interpret data, and present findings (L)

7.SA2.1

identifying and evaluating the sources used to support scientific statements

7.SA3.1

designing and conducting a simple investigation about the local environment (L)

7.SB1.1

using physical properties (i.e., density, boiling point, freezing point, conductivity) to differentiate among and/or separate materials (i.e., elements, compounds, and mixtures)

7.SB2.1

explaining that energy (i.e., heat, light, chemical, electrical, mechanical) can change form

7.SB3.1

recognizing that most substances can exist as a solid, liquid, or gas depending on the motion of their particles

7.SB4.1

illustrating that unbalanced forces will cause an object to accelerate

7.SB4.2

recognizing that electric currents and magnets can exert a force on each other

7.SB4.3

describing the characteristics of a wave (i.e., amplitude, wavelength, and frequency)

7.SC1.1

comparing and contrasting sexual and asexual reproduction

7.SC1.2

describing possible outcomes of mutations (i.e., no effect, damage, benefit)

7.SC2.1

describing the basic structure and function of plant and animal cells

7.SC2.2

identifying the seven levels of classification of organisms

7.SC2.3

identifying and describing the functions of human organs (i.e., heart, lungs, brain)

7.SC3.1

recognizing and explaining that organisms can cause physical and chemical changes (e.g., digestion, growth, respiration, photosynthesis) to matter and recognizing and explaining the importance of energy transfer in these changes

7.SC3.2

classifying organisms within a food web as producers, consumers, or decomposers

7.SD1.1

describing the rock cycle and its relationship to igneous, metamorphic, and sedimentary rocks

7.SD1.2

explaining the water cycles connection to changes in the Earths surface

7.SD2.1

identifying strategies (e.g., reforestation, dikes, wind breaks, off road activity guidelines) for minimizing erosion

7.SD2.2

describing how the movement of the tectonic plates results in both slow changes (e.g., formation of mountains, ocean floors, and basins) and short-term events (e.g., volcanic eruptions, seismic waves, and earthquakes) on the surface

7.SD3.1

describing the weather using accepted meteorological terms (e.g., pressure systems, fronts, precipitation)

7.SD3.2

recognizing the relationship between phase changes (i.e., sublimation, condensation, evaporation) and energy transfer

7.SD4.1

comparing and contrasting characteristics of planets and stars (i.e., light reflecting, light emitting, orbiting, orbited, composition)

7.SD4.2

using light years to describe distances between objects in the universe

7.SE1.1

describing how public policy affects the students life (e.g., public waste disposal) (L)

7.SE2.1

identifying, designing, testing, and revising solutions to a local problem (L)

7.SE2.2

comparing the students work to the work of peers in order to identify multiple paths that can be used to investigate a question or problem* (L)

7.SE3.1

recognizing the effects of a past scientific discovery, invention, or scientific breakthrough (e.g., DDT, internal combustion engine)

7.SF1.1

investigating the basis of local knowledge (e.g., describing and predicting weather) and sharing that information (L). Cross referenced with SA3.1.

7.SG2.1

explaining differences in results of repeated experiments

7.SG3.1

revising a personal idea when presented with experimental/observational data inconsistent with that personal idea (e.g., the rates of falling bodies of different masses) (L)
