### 1: The student knows and applies scientific concepts and principles to understand the properties, structures, and changes in physical, earth/space, and living systems.

#### 1.1: Understand how properties are used to identify, describe, and categorize substances, materials, and objects and how characteristics are used to categorize living things.

1.1.2: Apply an understanding of direction, speed, and acceleration when describing the linear motion of objects.

1.1.2.a: Describe the linear motion (speed, direction, and acceleration) of an object over a given time interval relative to Earth or some other object (e.g., as a car accelerates onto a freeway the car speeds up from 30 km/hr to 90 km/hr in 10 sec.).

1.1.2.b: Determine and explain the average speed of an object over a given time interval when the object is moving in a straight line.

#### 1.2: Understand how components, structures, organizations, and interconnections describe systems.

1.2.1: Analyze how systems function, including the inputs, outputs, transfers, transformations, and feedback of a system and its subsystems.

1.2.1.b: Explain inputs, outputs, transfers, transformations, and feedback of matter, energy, and information in a system.

1.2.2: Analyze energy transfers and transformations within a system, including energy conservation.

1.2.2.a: Describe and determine the energy inputted to an object as work (i.e., work on an object is the product of the force acting on the object and the distance the object moves as the force acts).

1.2.2.b: Describe how a machine transfers work and transforms force and distance through a force-distance tradeoff (e.g., a small force acting over a long distance can be transformed to a large force acting over a short distance).

1.2.2.c: Examine and explain how energy is transferred within and among systems.

1.2.8: Understand the organization and function of human body structures and organs and how these structures and organs interconnect.

1.2.8.a: Analyze how human organ systems regulate growth, development, and life functions.

#### 1.3: Understand how interactions within and among systems cause changes in matter and energy.

1.3.1: Analyze the forces acting on objects.

1.3.1.c: Measure and describe the sum of all the forces acting on an object.

1.3.1.d: Describe how forces between objects occur, both when the objects are touching and when the objects are apart.

1.3.1.e: Explain that the strength of a gravitational force between two objects depends on the mass of the objects and the distance between the objects.

1.3.2: Analyze the effects of balanced and unbalanced forces on the motion of an object.

1.3.2.b: Explain how unbalanced forces change the speed and/or direction of motion of different objects moving along a straight line, 2nd Law of Motion (e.g., a 2-kg object needs twice the unbalanced force to speed up the same amount as a 1-kg object).

1.3.2.c: Investigate and describe that forces always come in pairs, 3rd Law of Motion (e.g., pull a spring scale against another spring scale, as water blasts out of a bottle rocket two forces act — a force on the water and an equal force on the rocket).

1.3.3: Analyze the factors that affect physical, chemical, and nuclear changes and understand that matter and energy are conserved.

1.3.3.a: Investigate and analyze the effect of different factors on the rate of a physical and chemical change (e.g., temperature, surface area, pressure, catalysts).

1.3.3.b: Explain how chemical changes produce substances with different chemical properties and the same total mass.

1.3.3.d: Recognize and explain that the rate of radioactive decay of a substance is constant, not affected by any factors (e.g., the half-life of a radioactive substance is constant over a long time and a wide range of conditions found on Earth).

1.3.4: Analyze processes that have caused changes to the features of Earth's surface, including plate tectonics.

1.3.4.c: Describe the causes and effects of volcanoes, hot spots, and earthquakes in Washington State and elsewhere (e.g., subduction of the Juan de Fuca plate causes earthquakes that may cause seismic sea waves; earthquakes along the Seattle fault cause P, S, and surface seismic waves).

1.3.4.d: Explain how substances change as they move through Earth’s systems (e.g., carbon cycle, nitrogen cycle, burning of wood and fossil fuels).

1.3.5: Analyze a variety of evidence, including rock formations, fossils, and radioactive decay, to construct a sequence of geologic events.

1.3.5.a: Explain how decay rates of radioactive materials in rock layers are used to establish the age of fossil remains or the time of geologic events.

1.3.6: Analyze the factors that influence weather and climate.

1.3.6.b: Explain how greenhouse gases in the atmosphere affect climate (e.g., global warming).

1.3.8: Understand how organisms, including cells, use matter and energy to sustain life and that these processes are complex, integrated, and regulated.

1.3.8.b: Describe how energy is transferred and transformed from the Sun to energy-rich molecules during photosynthesis.

1.3.10: Analyze the living and nonliving factors that affect organisms in ecosystems.

1.3.10.a: Describe how matter and energy are transferred and cycled through ecosystems (i.e., matter and energy move from plants to herbivores/omnivores to carnivores and decomposers).

1.3.10.b: Compare different ecosystems in terms of the cycling of matter and flow of energy.

1.3.10.d: Describe the living and nonliving factors that limit the size and affect the health of a population in an ecosystem.
