Clarification Statement and Assessment Boundary

Clarification Statement: none

Assessment Boundary: none

 

Make observations of plants and animals to compare the diversity of life in different habitats. 2-LS4-1

Clarification Statement and Assessment Boundary

Clarification Statement: Emphasis is on the diversity of living things in each of a variety of different habitats.

Assessment Boundary: Assessment does not include specific animal and plant names in specific habitats.

Science and Engineering Practices

Developing and Using Models

Modeling in K–2 builds on prior experiences and progresses to include using and developing models (i.e., diagram, drawing, physical replica, diorama, dramatization, or storyboard) that represent concrete events or design solutions.

Develop a simple model based on evidence to represent a proposed object or tool. (2-LS2-2)

Planning and Carrying Out Investigations

Planning and carrying out investigations to answer questions or test solutions to problems in K–2 builds on prior experiences and progresses to simple investigations, based on fair tests, which provide data to support explanations or design solutions.

Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence to answer a question. (2-LS2-1)

Make observations (firsthand or from media) to collect data which can be used to make comparisons. (2-LS4-1)

Connections to Nature of Science

Science Knowledge Is Based on Empirical Evidence

Scientists look for patterns and order when making observations about the world. (2-LS4-1)

Common Core State Standards Connections

ELA/Literacy
  • SL.2.5 - Create audio recordings of stories or poems; add drawings or other visual displays to stories or recounts of experiences when appropriate to clarify ideas, thoughts, and feelings. (2-LS2-2)
  • 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-LS2-1), (2-LS4-1)
  • W.2.8 - Recall information from experiences or gather information from provided sources to answer a question. (2-LS2-1), (2-LS4-1)
Mathematics
  • 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-LS2-2), (2-LS4-1)
  • MP.2 - Reason abstractly and quantitatively. (2-LS2-1), (2-LS4-1)
  • MP.4 - Model with mathematics. (2-LS2-1), (2-LS2-2), (2-LS4-1)
  • MP.5 - Use appropriate tools strategically. (2-LS2-1)
