SCIENCE.2.6.A — Vertical Alignment

Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.

S.1.6.A

classify objects by observable physical properties, including, shape, color, and texture, and attributes such as larger and smaller and heavier and lighter;

S.K.6

identify and record observable physical properties of objects, including shape, color, texture, and material, and generate ways to classify objects.

S.2.6.A

classify matter by observable physical properties, including texture, flexibility, and relative temperature, and identify whether a material is a solid or liquid;

S.3.6.A

measure, test, and record physical properties of matter, including temperature, mass, magnetism, and the ability to sink or float in water;

S.3.6.B

describe and classify samples of matter as solids, liquids, and gases and demonstrate that solids have a definite shape and that liquids and gases take the shape of their container;

S.4.6.A

classify and describe matter using observable physical properties, including temperature, mass, magnetism, relative density (the ability to sink or float in water), and physical state (solid, liquid, gas);

S.5.6.A

compare 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;

S.6.6.A

compare solids, liquids, and gases in terms of their structure, shape, volume, and kinetic energy of atoms and molecules;

S.6.6.C

identify elements on the periodic table as metals, nonmetals, metalloids, and rare Earth elements based on their physical properties and importance to modern life;

S.6.6.D

compare the density of substances relative to various fluids; and

S.8.6.C

describe the properties of cohesion, adhesion, and surface tension in water and relate to observable phenomena such as the formation of droplets, transport in plants, and insects walking on water;

S.8.6.D

compare and contrast the properties of acids and bases, including pH relative to water; and

CHEM.5.A

explain the development of the Periodic Table over time using evidence such as chemical and physical properties;

CHEM.5.B

predict the properties of elements in chemical families, including alkali metals, alkaline earth metals, halogens, noble gases, and transition metals, based on valence electrons patterns using the Periodic Table; and

IPC.7.C

explain how physical and chemical properties of substances are related to their usage in everyday life such as in sunscreen, cookware, industrial applications, and fuels;

CHEM.12.B

define acids and bases and distinguish between Arrhenius and Bronsted-Lowry definitions;

CHEM.12.C

differentiate between strong and weak acids and bases;

AQUA.5.A

describe how the shape and polarity of the water molecule make it a "universal solvent" in aquatic systems;

AQUA.5.B

identify how aquatic ecosystems are affected by water's properties of adhesion, cohesion, surface tension, heat capacity, and thermal conductivity; and

AQUA.5.C

explain how the density of water is critical for organisms in cold environments.

AQUA.8.B

collect and analyze pH, salinity, temperature, mineral content, nitrogen compounds, dissolved oxygen, and turbidity data periodically, starting with baseline measurements; and

AQUA.11.A

examine basic principles of fluid dynamics, including hydrostatic pressure, density as a result of salinity, and buoyancy;

AQUA.11.C

explain how fluid dynamics causes upwelling and lake turnover; and

SCIENCE.2.6.A — Breakout of skills

Breakouts are the component parts that make up a student expectation. A breakout shows a distinct concept a student should know or a distinct skill that a student should be able to demonstrate.

The student is expected to

classify matter by observable physical properties, including

flexibility

relative temperature

texture

identify whether a material is a solid or liquid
