ESS1 (K-2) - 1
Students demonstrate an understanding of earth materials by …

1a describing, comparing, and sorting rocks and soils by similar or different physical properties (e.g., size, shape, color, texture, smell, weight).

1b recording observations/data about physical properties.

1c using attributes of properties to state why objects are grouped together (e.g., rocks that are shiny or not shiny).
ESS1 (3-4) - 1
Students demonstrate an understanding of earth materials by …

1a describing, comparing, and sorting rocks, soils, and minerals by similar or different physical properties (e.g., size, shape, color, texture, smell, weight, temperature, hardness, composition).

1b recording and analyzing observations/data about physical properties (e.g., within a grouping, which characteristics are the same and which are different).

1c citing evidence (e.g., prior knowledge, data) to support why rocks, soils, or minerals are classified/not classified together.

1d identifying the four basic materials of the earth (water, soil, rocks, air).
ESS1 (5-6) - 1
Students demonstrate an understanding of processes and change over time within earth systems by …

1a identifying and describing the layers of the earth.

1b plotting location of volcanoes and earthquakes and explaining the relationship between the location of these phenomena and faults.
ESS1 (7-8) - 1
Students demonstrate an understanding of processes and change over time within earth systems by …

1a citing evidence and developing a logical argument for plate movement using fossil evidence, layers of sedimentary rock, location of mineral deposits, and shape of the continents.
ESS1 (9-11) - 1
Students demonstrate an understanding of processes and change over time within earth systems by …

1a. plotting the location of mountain ranges and recent earthquakes and volcanic eruptions to identify any existing patterns.
