[2.ESS.2.3] - Use examples obtained from informational sources to explain that water is found in the ocean, rivers and streams, lakes and ponds, and may be solid or liquid.

Resources:

Predecessor Standards:

  • K.MD.A.2
    Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.
  • K.PS.1.1
    Investigate and communicate the idea that different kinds of materials can be solid or liquid depending on temperature. Clarification Statements: Materials chosen must exhibit solid and liquid states in a reasonable temperature range for kindergarten students (e.g., 0–80°F), such as water, crayons, or glue sticks; Only a qualitative description of temperature, such as hot, warm, and cool, is expected.

Successor Standards:

  • 5.ESS.2.2
    Describe and graph the relative amounts of salt water in the ocean; fresh water in lakes, rivers, and groundwater; and fresh water frozen in glaciers and polar ice caps to provide evidence about the availability of fresh water in Earth’s biosphere. State Assessment Boundary: Inclusion of the atmosphere is not expected in state assessment.

Same Level Standards:

  • RI.2.7
    Explain how specific images (e.g., a diagram showing how a machine works) contribute to and clarify a text.
  • RI.2.9
    Compare and contrast the most important points presented by two texts on the same topic.
