• Understand energy flows and matter cycles within and among Earth’s systems, including the sun and Earth’s interior as primary energy sources. Study the water cycle, and how changes the properties of water and movement of water impact Earth’s systems.

• Describe how humans depend on the Earth for different resources, and analyze how human activities have impacted Earth’s biosphere and climate. Map the history of natural hazards in a region and understand related geological forces.

• Evaluate ways to reduce the impact of global warming.

When Studying Earth and Space Science You May Find Students:

• Developing models to describe the cycling of water through Earth’s systems and to describe the processes that determine regional climates.

• Analyzing and interpreting data on natural hazards to forecast future catastrophic events and inform the development of technologies to mitigate their effects.

• Constructing an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth’s systems, and applying scientific principles to design a method for minimizing human impact on the environment

• Understand that organisms reproduce and transfer their genetic information to their offspring, and that there are processes by which characteristics or traits are passed from one generation to another.

• Recognize that ecosystems are dynamic in nature, and are sustained by a continuous flow of energy that originates primarily from the sun. Analyze how organisms and populations of plants and animals in ecosystems are dependent on environmental interactions with living and nonliving things, and that variations in populations of organisms is beneficial for their survival and reproduction in an environment.

When Studying Life Science You May Find Students:

• Constructing an explanation and reasoning mathematically to determine how environmental and genetic factors affect the growth of organisms. They can connect this to understand the role animal behavior (e.g., nest building), specialized plant structures (e.g., bright colors in flowers to attract bees) and adaptation play in reproduction.

• Constructing explanations based on evidence (e.g., fossil records, complexity of anatomical traits, etc.) to support fundamental understandings of natural selection and evolution. Students will use ideas of genetic variation in a population to make sense of organisms surviving and reproducing, hence passing on the traits of the species. 

• Applying multiple practices to gain a deeper understanding of natural resources and the cycling of matter and the flow of energy in ecosystems. Studying patterns of the interactions among organisms within an ecosystem and examining the impact that shifts in biotic and abiotic factors have on the populations of organisms. 

• Evaluating competing design solutions for maintaining biodiversity and ecosystem services like water purification, recycling, or prevention of erosion.

• Recognize that matter is composed of atoms and molecules, and that an understanding of the properties of atoms can be used to explain the properties of substances and diversity of materials we engage with on a daily basis. 

• Understand how reacting substances rearrange to form new substances, and that through the process matter is conserved. Recognize that some reactions release energy and others absorb energy.

•  Explain how motion is described and how the mass and force influence motion, as part of this analyze interactions and energy transfer between two objects in motion. 

• Understand that forces, like gravity,  that act a distance can be explained by force fields that extend through space and that their impact on objects can be analyzed.

• Recognize that kinetic energy, the energy of motion, can be distinguished from the various forms of potential (stored) energy, and explain how changes in energy forms can be tracked through physical or chemical interactions. Explore the relationship between the temperature and the total energy of a system. 

• Explore the properties of waves, and understand how waves transmit energy, and gather information about technology that transmit information as wave pulses.  This model can explain many phenomena which include light and sound.

When Studying Physical Science You May Find Students:

• Developing models to describe the atomic composition of simple molecules and extended structures like water, table salt, and other common substances. 

• Analyzing and interpreting data from various sources, including hands on labs,  to determine if a chemical reaction has occurred. 

• Developing models that demonstrate understanding of the relationship between temperature and particle motion or wave transmission through various materials.

• Planning investigations to provide evidence about the impact of force and mass on an object's motion; constructing and testing a device that can keep an object hot or cold for extended periods of time.

• Constructing and presenting arguments using evidence to support claims around the interaction between mass and gravitational force.
