The program emphasizes the important connections between these subjects and their cross-disciplinary applications. It fosters curiosity, encourages problem solving, and promotes analytical thinking—cultivating the skills students need to be future scientists.
Reading tips and exercises help students unlock science content. These are available at the beginning and throughout each chapter to maximize comprehension.
Math Skills Development
Math Skills sections link mathematics directly to science concepts. Practice problems let students check their understanding and apply what they’ve learned.
Inquiry and Hands-On Learning
Each chapter begins with an Inquiry Lab activity that gets students thinking. Quick Labs and Chapter Labs reinforce key science concepts, with a focus on experimental skills.
In addition to the Interactive Online Edition, students have access to a variety of digital resources for each chapter, including:
