Performance Expectations

  1. Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season. 3-ESS2-1

    Clarification Statement and Assessment Boundary
  2. Obtain and combine information to describe climates in different regions of the world. 3-ESS2-2

    Clarification Statement and Assessment Boundary

A Peformance Expectation (PE) is what a student should be able to do to show mastery of a concept. Some PEs include a Clarification Statement and/or an Assessment Boundary. These can be found by clicking the PE for "More Info." By hovering over a PE, its corresponding pieces from the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts will be highlighted.

By clicking on a specific Science and Engineering Practice, Disciplinary Core Idea, or Crosscutting Concept, you can find out more information on it. By hovering over one you can find its corresponding elements in the PEs.

Common Core State Standards Connections


  • RI.3.1 - Ask and answer questions to demonstrate understanding of a text, referring explicitly to the text as the basis for the answers. (3-ESS2-2)
  • RI.3.9 - Compare and contrast the most important points and key details presented in two texts on the same topic. (3-ESS2-2)
  • W.3.8 - Recall information from experiences or gather information from print and digital sources; take brief notes on sources and sort evidence into provided categories. (3-ESS2-2)


  • 3.MD.A.2 - Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem. (3-ESS2-1)
  • 3.MD.B.3 - Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step "how many more" and "how many less" problems using information presented in scaled bar graphs. (3-ESS2-1)
  • MP.2 - Reason abstractly and quantitatively. (3-ESS2-1), (3-ESS2-2)
  • MP.4 - Model with mathematics. (3-ESS2-1), (3-ESS2-2)
  • MP.5 - Use appropriate tools strategically. (3-ESS2-1)

Resources & Lesson Plans

  • More resources added each week!
    A team of teacher curators is working to find, review, and vet online resources that support the standards. Check back often, as NSTA continues to add more targeted resources.
  • Students are expected to collect and graph weather data, then analyze historical averages to develop an understanding of the difference between weather and climate.

  • The book, Sky Notebook, introduces students to the concept of collecting weather data to observe patterns. The book is written by a scientist who measures daily weather and records his observations in a notebook. The book allows students …

  • This resource allows students to observe and manipulate a wide variety of data sets on a world map. The weather/climate tab provides visual representations of climate data, but students can make other curricular connections as well. Students or te…

  • This resource acts as a climate data warehouse in the form of graphs and tables for cities across the US, a linchpin for any three-dimensional climate unit. The resource is not written specifically for educators. Its sister web…

  • This lesson provides an engaging way for students to investigate different climates from around the world. The teacher prints postcards from "grandma" along with graphs of climates from five different regions. Students must interpret the…

  • Students analyze NASA wind speed climate data using a line plot graph. The lesson includes guiding questions to help students understand the basic functions of a line plot. It serves as an introduction to analyzing data and climate data in ge…
