Carolina Biological K-8 Curriculum – April 2024

2nd Grade

Matter and Its Interactions


Students who demonstrate understanding can:



Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose. 2-PS1-2

Clarification Statement and Assessment Boundary

Clarification Statement: Examples of properties could include, strength, flexibility, hardness, texture, and absorbency.

Assessment Boundary: Assessment of quantitative measurements is limited to length.

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.

Analyze data from tests of an object or tool to determine if it works as intended. (2-PS1-2)

Disciplinary Core Ideas

PS1.AStructure and Properties of Matter

Different properties are suited to different purposes. (2-PS1-2)

Crosscutting Concepts

Cause and Effect

Simple tests can be designed to gather evidence to support or refute student ideas about causes. (2-PS1-2)

Connections to Engineering, Technology, and Applications of Science

Influence of Science, Engineering, and Technology on Society and the Natural World

Every human-made product is designed by applying some knowledge of the natural world and is built using materials derived from the natural world. (2-PS1-2)

Common Core State Standards Connections

  • RI.2.8 - Describe how reasons support specific points the author makes in a text. (2-PS1-2)
  • W.2.7 - Participate in shared research and writing projects (e.g., read a number of books on a single topic to produce a report; record science observations). (2-PS1-2)
  • W.2.8 - Recall information from experiences or gather information from provided sources to answer a question. (2-PS1-2)
  • 2.MD.D.10 - Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems using information presented in a bar graph. (2-PS1-2)
  • MP.2 - Reason abstractly and quantitatively. (2-PS1-2)
  • MP.4 - Model with mathematics. (2-PS1-2)
  • MP.5 - Use appropriate tools strategically. (2-PS1-2)
