Reading Levels

These books contain three developmentally appropriate reading levels for each grade span.

Low
Mid
High

Each level of the book conveys similar concepts, images, and vocabulary.

Habitats / Environment

The world is made up of many different kinds of habitats. Each one has a distinct blend of environmental factors, including latitude, elevation, climate, land features, water features, plant life, and animal life. The organisms that live in each habitat are specially adapted to live there and are interdependent. This unit helps students understand how and why habitats differ and provides a starting point for students to explore some of the many fascinating habitats in the natural environment. The unit also addresses the fact that natural forces and human activity can have considerable effects on natural habitats. Taking action to protect a habitat from harmful changes could provide a healthy and sustainable environment for many species in the future.

Read-First Model

In the read-first model, students begin by reading texts that help them build a foundation of understanding with the core science ideas of the unit. Then they engage in hands-on investigations and use other resources to explore examples related to the concepts they read about. Students learn about general concepts before using deductive reasoning to apply them to specific examples.

Vocabulary resources can be used at multiple points throughout the unit to develop and strengthen students� fluency with the disciplinary language of science. TIP: Challenge students to maintain a concept web throughout the unit that connects the examples they explore later in the roadmap back to the core ideas they read about in the Unit Nonfiction Book.

Do-First Model

In the do-first model*, students are immersed in unit concepts by completing hands-on investigations that allow them to apply science and engineering practices and construct their own explanations of core ideas. Then students read texts, watch videos, and complete more investigations that help them confirm or refine their explanations. Vocabulary resources can be used at multiple points throughout the unit to develop and strengthen students� fluency with the disciplinary language of science. TIP: Have students use a science journal to record the examples they explore through activities and readings, then challenge them to design a concept web that connects those examples to the core ideas they read about in the Unit Nonfiction Book toward the end of the roadmap.

* This model may also be referred to as the discovery method, in which students use inductive reasoning to determine broad concepts by first exploring examples.

Project-Based Model

In the project-based model*, students work in teams to investigate a science question or design a solution to an engineering challenge. The PBL Project Organizer, SAZ Journal, completed project, and group presentation all allow students to demonstrate what they have learned and accomplished. The PBL Teaching Tips help teachers facilitate the project, while rubrics for teachers and students can be used to assess group and individual performance. During planning and execution, students use other unit resources to build their understanding of core concepts that they can apply to their project.
