Patterns are recognizable in the natural world and among objects in the sky. 

Students understand that weather, seasons of the year, and day and night are repeated patterns. 

Materials found on Earth can be used and classified.

Patterns, cycles, and systems are recognizable in the natural world and among objects in the sky. 

Students make informed choices by understanding weather and seasonal patterns. 

Students understand that natural resources on Earth, including rocks, soil, and water, are used by humans and can be conserved. 

Students observe objects in the sky, including the Sun and the Moon, and collect and analyze weather data. 

In addition, students identify natural and manmade resources and how they can be conserved. 

Students learn that there are recognizable processes that change the Earth over time. Students compare day-to-day changes in weather. 

They also investigate how soil is formed through the processes of weathering and decomposition. 

Students model rapid changes to Earth's surface as well as explore ways to conserve Earth's resources. 

Students recognize that there are identifiable objects and patterns in Earth's solar system. 

Students model the orbits of the Sun, Earth, and Moon as well as describe their relationship to each other. 

This will set the foundation for Grade 4 when they look at changes in the appearance of the Moon. 

Students also identify the sequence of the planets in Earth's solar system.

Students learn about processes on Earth that create patterns of change. 

These processes include the water cycle, weathering, erosion, deposition, the appearance of the Moon, and seasons. 

Students will build on this understanding in Grade 5 when they learn about day and night, shadows, and the rotation of Earth on its axis. 

Finally, students identify Earth's resources and classify them as renewable or nonrenewable. 

This strand is focused on identifying recognizable patterns and processes as students learn about Earth's rotation and demonstrate the effects this movement has on Earth's surface, including day and night, shadows, and the rotation of Earth on its axis. 

Students continue their learning of patterns and processes on Earth while exploring weather, climate, the water cycle, the formation of sedimentary rock and fossil fuels, and the formation of landforms. 

Finally, students learn ways to manage natural resources to support a healthy environment. 

Cycles within Sun, Earth, and Moon systems are studied as students learn about seasons and tides. 

Students identify that the Earth is divided into spheres and examine the processes within and organization of the geosphere. 

Researching the advantages and disadvantages of short- and long-term uses of resources enables informed decision-making about resource management. 

Students explore characteristics and organization of objects and the role of gravity within our solar system. 

Earth has a specific set of characteristics that allows life to exist. 

Students further their understanding of the geosphere by illustrating how Earth's features change over time through tectonic movement. 

Students investigate how humans depend on and affect the hydrosphere. 

Students learn that stars and galaxies are part of the universe. 

In addition, students use data to research scientific theories of the origin of the universe. 

Students learn how interactions in solar, weather, and ocean systems create changes in weather patterns and climate. 

In addition, students understand that climate can be impacted by natural events and human activities.
