SCIENCE.8.9 — 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.

Previous grade

S.4.8.A

investigate and identify the transfer of energy by objects in motion, waves in water, and sound;

S.5.8.A

investigate 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;

S.6.8.B

describe how energy is conserved through transfers and transformations in systems such as electrical circuits, food webs, amusement park rides, or photosynthesis; and

S.6.8.C

explain how energy is transferred through transverse and longitudinal waves.

S.7.8.A

investigate methods of thermal energy transfer into and out of systems, including conduction, convection, and radiation;

S.8.9

Earth and space. The student describes the characteristics of the universe and the relative scale of its components. The student is expected to:

IPC.6.C

plan and conduct an investigation to provide evidence that energy is conserved within a closed system;

IPC.6.D

investigate and demonstrate the movement of thermal energy through solids, liquids, and gases by convection, conduction, and radiation such as weather, living, and mechanical systems;

IPC.6.E

plan and conduct an investigation to evaluate the transfer of energy or information through different materials by different types of waves such as wireless signals, ultraviolet radiation, and microwaves;

PHYS.7.C

apply the concept of conservation of energy using the work-energy theorem, energy diagrams, and energy transformation equations, including transformations between kinetic, potential, and thermal energy;

PHYS.8.A

examine and describe simple harmonic motion such as masses on springs and pendulums and wave energy propagation in various types of media such as surface waves on a body of water and pulses in ropes;

CHEM.13.B

investigate the process of heat transfer using calorimetry;

CHEM.13.D

perform calculations involving heat, mass, temperature change, and specific heat.

ENVIR.5.B

explain the cycling of water, phosphorus, carbon, silicon, and nitrogen through ecosystems, including sinks, and the human interactions that alter these cycles using tools such as models;

EARTH.8.A

evaluate heat transfer through Earth's systems by convection and conduction and include its role in plate tectonics and volcanism;

ENVIR.7.B

relate biogeochemical cycles to the flow of energy in ecosystems, including energy sinks such as oil, natural gas, and coal deposits;

ENVIR.7.C

explain the flow of heat energy in an ecosystem, including conduction, convection, and radiation; and

ENVIR.7.D

identify and describe how energy is used, transformed, and conserved as it flows through ecosystems.
