K-ESS2-1 Use and share observations of local weather conditions to describe patterns over time.
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.
This resource appears to be designed to build towards this performance expectation, though the resource developer has not explicitly stated so.
Comments about Including the Performance Expectation
To fully meet Performance Expectation, students will observe weather for more than five days. Students use the weather station to make observations about local weather. Students can use observations from the weather station to collect data describe patterns over time.
