3-LS3-2 Heredity: Inheritance and Variation of Traits

3-LS3-2   Heredity: Inheritance and Variation of Traits

Students who demonstrate understanding can:

3-LS3-2. Use evidence to support the explanation that traits can be influenced by the environment. [Clarification Statement: Examples of the environment affecting a trait could include normally tall plants grown with insufficient water are stunted; and, a pet dog that is given too much food and little exercise may become overweight.]
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

Constructing Explanations and Designing Solutions

Constructing explanations and designing solutions in 3–5 builds on K–2 experiences and progresses to the use of evidence in constructing explanations that specify variables that describe and predict phenomena and in designing multiple solutions to design problems.

Disciplinary Core Ideas

Articulation of DCIs across grade-levels:

MS.LS1.B

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-LS3-2)
RI.3.2 Determine the main idea of a text; recount the key details and explain how they support the main idea. (3-LS3-2)
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-LS3-2)
W.3.2 Write informative/explanatory texts to examine a topic and convey ideas and information clearly. (3-LS3-2)
SL.3.4 Report on a topic or text, tell a story, or recount an experience with appropriate facts and relevant, descriptive details, speaking clearly at an understandable pace. (3-LS3-2)
Mathematics —
MP.2 Reason abstractly and quantitatively. (3-LS3-2)
MP.4 Model with mathematics. (3-LS3-2)
3.MD.B.4 Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units—whole numbers, halves, or quarters. (3-LS3-2)
