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.

Force and Motion

Force and motion are fundamental to all matter in the universe and are integral parts of our daily lives. A force is anything that can push or pull an object. Forces influence objects that are at rest or that are already in motion. Isaac Newton's three laws of motion describe how forces interact with objects to influence motion. These laws involve inertia, mass, velocity, and momentum. Key forces include gravity, friction, and magnetism. A force is required to do work, and generating a force requires energy. Energy can be stored as potential energy, or it can have kinetic energy�the energy of motion. Energy can also be converted and exchanged through energy transfer.

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.
