Alaska Standards for Fourth Grade Science

AK.A1. Science as Inquiry and Process (SA1, SA2, SA3)

[4] SA1.1. The student develops an understanding of the processes of science by asking questions, predicting, observing, describing, measuring, classifying, making generalizations, inferring and communicating.

[4] SA1.2. The student develops an understanding of the processes of science by observing, measuring and collecting data from explorations and using this information to classify, predict, and communicate.

AK.B1. Concepts of Physical Science (SB1, SB2, SB3, SB4)

[4] SB1.1. The student demonstrates an understanding of the structure and properties of matter by identifying and comparing the characteristics of gases, liquids, and solids.

[4] SB2.1. The student demonstrates an understanding of how energy can be transformed, transferred, and conserved by investigating the effectiveness of different insulating and conducting materials with respect to heat flow and record the results. (L)

[4] SB3.1. The student demonstrates an understanding of the interactions between matter and energy and the effects of these interactions on systems by explaining that temperature changes cause changes in phases of substances (e.g., ice changing to liquid water and liquid water to water vapor).

[4] SB4.1. The student demonstrates an understanding of motions, forces, their characteristics, relationships, and effects by simulating that changes in speed or direction of motion are caused by forces. (L)

AK.C1. Concepts of Life Science (SC1, SC2, SC3)

[4] SC1.1. The student demonstrates an understanding of how science explains changes in life forms over time, including genetics, heredity, the process of natural selection and biological evolution by showing the relationship between physical characteristics of Alaskan organisms and the environment in which they live.

[4] SC1.2. The student demonstrates an understanding of how science explains changes in life forms over time, including genetics, heredity, the process of natural selection and biological evolution by describing fossil evidence (e.g., casts, track ways, imprints, etc.) of extinct organisms.

[4] SC2.2. The student demonstrates an understanding of the structure, function, behavior, development, life cycles, and diversity of living organisms by describing the basic characteristics and requirements of living things.

[4] SC3.1. The student demonstrates an understanding that all organisms are linked to each other and their physical environments through the transfer and transformation of matter and energy by identifying examples of living and non-living things and the relationship between them (e.g., living things need water, herbivores need plants).

[4] SC3.2. The student demonstrates an understanding that all organisms are linked to each other and their physical environments through the transfer and transformation of matter and energy by identifying a simple food chain of familiar plans and animals, diagramming how energy flows through it, and describing the effects of removing one link.

AK.D1. Concepts of Earth Science (SD1, SD2, SD3, SD4)

[4] SD1.1. The student demonstrates an understanding of geochemical cycles by describing that most smaller rocks come from the breaking and weathering of larger rocks as part of the rock cycle.

[4] SD1.2. The student demonstrates an understanding of geochemical cycles by recognizing the physical properties of water as they relate to the rock cycle.

[4] SD2.1. The student demonstrates an understanding of the forces that shape Earth by observing models of how waves, wind, water, and ice shape and reshape the Earth's surface by eroding rock and soil. (L)

[4] SD2.2. The student demonstrates an understanding of the forces that shape Earth by identifying causes (i.e., earthquakes, tsunamis, volcanoes, floods, landslides, and avalanches) of rapid changes on the surface.

[4] SD3.1. The student demonstrates an understanding of cycles influenced by energy from the sun and by Earth's position and motion in our solar system by recognizing changes to length of daylight over time and its relationship to seasons.

[4] SD4.1. The student demonstrates an understanding of the theories regarding the origin and evolution of the universe by recognizing that stars are like the sun but are so far away that they look like points of light.

[4] SD4.2. The student demonstrates an understanding of the theories regarding the origin and evolution of the universe by recognizing that objects have properties, locations, and movements that can be observed and described.

AK.SA. Science as Inquiry and Process: A student should understand and be able to apply the processes and applications of scientific inquiry. A student who meets the content standard should:

SA1. Develop an understanding of the processes of science used to investigate problems, design and conduct repeatable scientific investigations, and defend scientific arguments.

AK.SB. Concepts of Physical Science: A student should understand and be able to apply the concepts, models, theories, universal principles, and facts that explain the physical world. A student who meets the content standard should:

SB1. Develop an understanding of the characteristic properties of matter and the relationship of these properties to their structure and behavior.

SB2. Develop an understanding that energy appears in different forms, can be transformed from one form to another, can be transferred or moved from one place or system to another, may be unavailable for use, and is ultimately conserved.

SB3. Develop an understanding of the interactions between matter and energy, including physical, chemical, and nuclear changes, and the effects of these interactions on physical systems.

SB4. Develop an understanding of motions, forces, their characteristics and relationships, and natural forces and their effects.
