Unit 6

2nd Grade

Unit Summary

In this unit, students study two important body systems in depth, the digestive and urinary systems. Students will be challenged to think about how the human body is a miraculous machine, in particular how the digestive and urinary systems are crucial for survival, by deeply analyzing and exploring the steps in both systems. After learning about how both systems function, students will learn about nutrition and how what we eat can either positively or negatively impact the way our body functions. Students will explore what it means to eat a well-balanced meal and how added sugars harm their bodies. It is our hope that this unit will help students build a deeper understanding of the human body and how the decisions we make daily, especially with food, can either help or harm us.

This unit builds upon skills learned in previous units, and it is assumed that students are inquisitive consumers of text, asking and answering questions about the content they are learning as a way to deepen their understanding of new material. The core text for this unit, The First Human Body Encyclopedia, was chosen because of its wide range of text features and content. While reading the encyclopedia, students should be challenged to think about how the different text features help them locate information and also how the images and diagrams help them clarify the information they are learning. Students should also be challenged to think about the connection between scientific ideas, using language that refers to cause and effect and sequence, particularly when explaining how different systems function. Throughout the unit, students will use all of the strategies they learned in previous units to engage with classmates in partners, small groups, and whole class discussions. Students will continue to build on their peers’ talk and may begin to critique and analyze the reasoning of their peers when applicable.

Students will continue to build writing fluency by writing daily in response to the Target Task question using a variety of simple and complex sentences. Over the course of the unit, students work on brainstorming and writing strong informational and opinion paragraphs. Students have multiple opportunities to write informational pieces about how the human body works, crafting paragraphs that have strong topic sentences, supporting details, facts, and concluding statements. Students also have a chance to continue to refine their opinion writing by writing a letter to their mayor trying to convince them of ways to get more nutritious food to families.

Assessment

The following assessments accompany Unit 6.

Content Assessment

The Content Assessment pushes students to synthesize unit content knowledge or unit essential questions in writing. The Content Assessment should be used as the primary assessment because it shows mastery of unit content knowledge and standards.

Cold Read Assessment

The Cold Read Assessment tests students' ability to comprehend a "cold" or unfamiliar passage and answer standards-based questions. The Cold Read Assessment can be given in addition to the Content Assessment as a pulse point for what students can read and analyze independently, a skill often required for standardized testing.

Fluency Assessment

The Fluency Assessment allows teachers to monitor students' oral reading fluency progress with a reading passage drawn from one of the unit's core texts. Find guidance for using this assessment and supporting reading fluency in Teacher Tools.
