# Heredity: Inheritance and Variation of Traits

### Students who demonstrate understanding can:

#### Performance Expectations

1. Make observations to construct an evidence-based account that young plants and animals are like, but not exactly like, their parents.

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.

### Science and Engineering Practices

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.

## Planning Curriculum

### Common Core State Standards Connections

#### ELA/Literacy

• W.1.7 - Participate in shared research and writing projects (e.g., explore a number of “how-to” books on a given topic and use them to write a sequence of instructions). (1-LS3-1)
• W.1.8 - With guidance and support from adults, recall information from experiences or gather information from provided sources to answer a question. (1-LS3-1)

#### Mathematics

• 1.MD.A.1 - Order three objects by length; compare the lengths of two objects indirectly by using a third object. (1-LS3-1)
• MP.2 - Reason abstractly and quantitatively. (1-LS3-1)
• MP.5 - Use appropriate tools strategically. (1-LS3-1)

## 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.
• In this lesson, students explore similarities and differences between animal babies and their parents to answer the question: Do all animal babies look exactly like their parents? Students use observations from animal figurines and photo matching as ...

• This one-minute time lapse video shows the phenomenon of plant growth and development from seeds to flowers. This phenomenon could stimulate the following driving questions: What kinds of plants are these? Do all plants grow like this? What ...

• During this lesson students begin to investigate similarities and differences between parents and their children.  After working through an example with the teacher, students gather observations from photographs of each other’s families. & ...

• In this lesson students compare adult plants with young plants and then match pictures of adult animals with their young. They then are asked to identify specific physical traits of plants and animals that can be used to identify them. Note: The Pa ...
