# The Standards

### Earth's Systems

#### Students who demonstrate understanding can:

Use and share observations of local weather conditions to describe patterns over time. K-ESS2-1

Clarification Statement and Assessment Boundary

Clarification Statement: Examples of qualitative observations could include descriptions of the weather (such as sunny, cloudy, rainy, and warm); examples of quantitative observations could include numbers of sunny, windy, and rainy days in a month. Examples of patterns could include that it is usually cooler in the morning than in the afternoon and the number of sunny days versus cloudy days in different months.

Assessment Boundary: Assessment of quantitative observations limited to whole numbers and relative measures such as warmer/cooler.

##### Science and Engineering Practices

Analyzing and Interpreting Data

Analyzing data in K–2 builds on prior experiences and progresses to collecting, recording, and sharing observations.

###### Connections to Nature of Science

Science Knowledge Is Based on Empirical Evidence

### Common Core State Standards Connections

ELA/Literacy
• W.K.7 - Participate in shared research and writing projects (e.g., explore a number of books by a favorite author and express opinions about them). (K-ESS2-1)
Mathematics
• K.CC.A - Know number names and the count sequence. (K-ESS2-1)
• K.MD.A.1 - Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object. (K-ESS2-1)
• K.MD.B.3 - Classify objects into given categories; count the numbers of objects in each category and sort the categories by count. (K-ESS2-1)
• MP.2 - Reason abstractly and quantitatively. (K-ESS2-1)
