3-LS2-1 Ecosystems: Interactions, Energy, and Dynamics

Students who demonstrate understanding can:

3-LS2-1. Construct an argument that some animals form groups that help members survive.
The performance expectation above was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices

Engaging in Argument from Evidence

Engaging in argument from evidence in 3–5 builds on K–2 experiences and progresses to critiquing the scientific explanations or solutions proposed by peers by citing relevant evidence about the natural and designed world(s).

Disciplinary Core Ideas

LS2.D: Social Interactions and Group Behavior

Crosscutting Concepts

Cause and Effect

Connections to other DCIs in third grade: N/A

Articulation of DCIs across grade-levels:

1.LS1.B ; MS.LS2.A

Common Core State Standards Connections:

ELA/Literacy —
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-LS2-1)
RI.3.3 Describe the relationship between a series of historical events, scientific ideas or concepts, or steps in technical procedures in a text, using language that pertains to time, sequence, and cause/effect. (3-LS2-1)
W.3.1 Write opinion pieces on topics or texts, supporting a point of view with reasons. (3-LS2-1)
Mathematics —
MP.4 Model with mathematics. (3-LS2-1)
3.NBT Number and Operations in Base Ten. (3-LS2-1)
