Science Strands The books and lessons in this kit cover the three strands of science which encompass the Disciplinary Core Ideas. The icons in the lessons and on the back of the books denote each strand. One book in this kit is devoted completely to scientific practices. This book describes how to think like a scientist and study the natural world.
English language learners have different instructional needs. Although these students may struggle with reading, that is not always the case. English language learners need different support depending on their level of English proficiency. The lesson plans in this kit offer suggestions to differentiate instruction for the unique needs of English language learners.

Differentiation
Students learn best when material is scaffolded appropriately. If a student is confronted with material that is too difficult, he or she may become frustrated and give up. However, if a student is not challenged enough, he or she may become bored and lose interest in the subject. Differentiation is not about making the work easy for students. Instead, it is about challenging all students appropriately.

INTRODUCTION Physical
Technology Connections The amount of information that is available to students through books, media, and the Internet is rapidly growing every day. Technology plays a key role in students’ ability to access that information, but teachers play a key role in helping develop student’s tools for understanding and using that information. Thus, it is vital that technology be integrated into the curriculum. According to the Partnership for 21st Century Skills (2009), the use of technology in the classroom can support effective curriculum implementation to do the following:
Space
• promote greater student achievement • increase student engagement • assess student performance • facilitate communication and collaboration • build student proficiencies in 21st-century skills

INTRODUCTION How to Use This Product (cont.) Using Interactiv-eBooks Interactiv-eBooks offer educators the unique opportunity to integrate technology into their curriculum for reading or content-area literacy instruction. Interactiv-eBooks guide students toward independent reading while exploring core concepts.
Space
ife
Teachers can determine whether to use Interactiv-eBooks in place of the print version of books or to supplement the use of the print version of books. Additionally, the use of Interactiv-eBooks will depend on the electronic resources available to both teachers and students (e.g., the availability of a projector, the number of student computer stations), and the method of use (e.g., whole‑class, small‑group, or individual‑learning opportunities). Interactiv-eBooks can benefit student learning in a variety of instructional settings, support English language acquisition, and further content and literacy learning. They are also perfect for lessons on an interactive whiteboard. The following best practices for reading and responding to literature can guide teachers to effectively incorporate Interactiv‑eBooks into the curriculum and optimize learning.
Features for the Interactiv-eBooks Navigation • Prerecorded audio leads students through the text. • A search bar helps easily locate key words and main ideas. Tools That Make Sense • Pen—Record notes directly on the page in the margins or annotate a picture. • Highlighter—Highlight the sentence that tells the main idea. • Spotlight—Examine graphic aids and develop visual literacy. • Notes—Record and save thoughts and observations about the text. • Print—Keep a printed record of student notes. • Zoom—Look more closely at a graphic element (such as an illustration) for analysis and inference. • Record Audio—Have students record themselves and analyze their fluency or record personal responses to text as they read.

Interactiv-eBooks and Interactive Whiteboards
Features for Building Content Learning
Teachers who use Interactiv-eBooks with interactive whiteboards have the double advantage of using both the Interactiv-eBook functions and the interactive whiteboard functions, such as touch-screen navigation, the ability to hide projected text or images with screen shades (for prediction purposes), or the interactive keyboard to type notes exclusively on the board. All the interactive whiteboard functions that teachers have come to rely on can be used in conjunction with the Interactiv‑eBooks.
• Activities bridge the gap between students’ background knowledge and the content presented in the book. • Easy-to-use tools give students the power to increase their comprehension and master vocabulary.

Interactiv-eBooks and Whole-Class Instruction
Interactiv-eBook and Small-Group Instruction
Whole-class instruction is best suited for introducing a text to students or for teaching specific strategies or content-area concepts as they apply to instructional standards and benchmarks. Every student engages with the same text at the same time. Interactiv‑eBooks support whole-class instruction in the following ways:
Interactiv-eBooks provide support for teachers who want to work with a specific group of students on a targeted comprehension or content skill. Choosing to use Interactiv-eBooks in this setting can greatly benefit instruction when compared to using individual print books only. For example:
• Projected on the board, they create a large canvas for a shared literacy experience. • Interactive features include the ability to highlight, circle, zoom, and make notes within the text:
➢ Teachers can provide student practice with before-reading tasks such as making predictions, and identifying and discussing key vocabulary words. ➢ Teachers and students can zoom in on specific words or images in the text. ➢ Teachers can write questions in the margins of the text for students to answer. ➢ Students can highlight key words and leave notes for further discussion.
• The pen tool can be used to model note‑taking skills. • The zoom tool can be used to draw attention to key aspects of the text.
arth
• The audio feature allows students to hear the correct pronunciation of words. • The text-to-speech audio highlighting allows students to see which words are being read and can be used as a model for fluent reading.
Physica
24
21653—Content and Literacy in Science Grade 3
• Students can quickly link to a projected Interactiv-eBook page. This limits transition times and fosters engagement. • When identifying targeted vocabulary, students can use the following:
➢ the highlighter, pen tool, shape tool, and note tool to support making connections and internalizing essential terms ➢ the visuals in the text to further support their vocabulary development ➢ the zoom tool to focus on key aspects of a visual feature that communicates vocabulary, such as the labels on a diagram
• Text-to-audio highlighting can be used to support struggling readers in practicing fluency. • Each Interactive-eBook provides accompanying interactive activities that can be used to strengthen and support student acquisition of essential concepts and vocabulary. • Using Interactiv-eBooks in conjunction with print books allows teachers to demonstrate and model reading skills and strategies or teach content using the interactive features while students read and follow along in their own printed text.

INTRODUCTION Physical
Interactiv-eBooks and English Language Support
Students can engage independently in Interactiv‑eBooks to build fluency, comprehension, and vocabulary skills. They can use the tools in Interactiv-eBooks to navigate the books on their own. The interactive features included increase rigor and allow students to extend their own knowledge. For example:
The Interactiv-eBooks provide support for English language learners through the following: • Text features such as labels, captions, and vocabulary pop-ups support vocabulary acquisition and language development.
• Students can use the audio and text highlighting features to listen to and reread the text in the Interactiv‑eBook several times to improve their sight‑vocabulary acquisition, automaticity, and accuracy. • Students can record themselves reading the text (microphone required) using the Interactiv-eBook’s record function and can then listen to their reading to reflect on their reading. The teacher can use this recording to rate students’ fluency, time their reading rate, and/or conduct a formal running record on the spoken text.
• Interactive activities support language acquisition and comprehension building.
Space
Interactiv-eBooks and Independent Practice
• Text-to-audio highlighting models fluency and rate of speech. • Audio recording allows students and teachers to reflect on student pronunciation and fluency.
Life
• Students can practice vocabulary and build comprehension skills by completing the vocabulary and comprehension activities at the end of each Interactiv‑eBook. Students can use the print function after completing the writing activity so answers can be assessed. • Use these activities in conjunction with supplemental, paper-pencil, or digital vocabulary or comprehension tasks for additional learning opportunities.

Forces You’ve worn headphones. You’ve watched TV. You’ve worked on a computer. Chances are you’ve also sat in a car. You may have even been on a high-speed roller coaster. The same force powers them all. That force is electromagnetism. The word is a mouthful. But breaking it down makes it easier to understand. Electro- means “electric,” as in electricity. Magnetism refers to the pull between certain metals. Electricity and magnetism were once thought to be two separate forces. But now we know they are both interrelated.

Electromagnetism at Work Electromagnetic cranes can be used to lift and move shipping containers onto trucks and ships. The electromagnet is turned on to lift the container. It is turned off to put the container in the required place.
