This course is a survey of American Literature from 1650 through 1820. It covers Early American and Puritan Literature, Enlightenment Literature, and Romantic Literature. It teaches in the context of American History and introduces the student to literary criticism and research.

American Literature I (1650–1860) examines significant literary works of early American and Puritan literature, the Enlightenment, American Romanticism, and pre-Civil War era. The course includes primary texts (many accompanied by video/audio options), historical background, literary criticism and interpretation, and instruction on writing about literature.

Analytical chemistry is more than a collection of analytical methods and an understanding of equilibrium chemistry; it is an approach to solving chemical problems. Although equilibrium chemistry and analytical methods are important, their coverage should not come at the expense of other equally important topics. The introductory course in analytical chemistry is the ideal place in the undergraduate chemistry curriculum for exploring topics such as experimental design, sampling, calibration strategies, standardization, optimization, statistics, and the validation of experimental results. Analytical methods come and go, but best practices for designing and validating analytical methods are universal. Because chemistry is an experimental science it is essential that all chemistry students understand the importance of making good measurements.

Published by OpenStax College, Anatomy and Physiology is a dynamic textbook for the yearlong Human Anatomy and Physiology course taught at most two- and four-year colleges and universities to students majoring in nursing and allied health. Anatomy and Physiology is 29 chapters of pedagogically effective learning content, organized by body system, and written at an audience-appropriate level. The lucid text, strategically constructed art, inspiring career features, and links to external learning tools address the critical teaching and learning challenges in the course.

Includes the study of the gross and microscopic structure of the systems of the human body with special emphasis on the relationship between structure and function. Integrates anatomy and physiology of cells, tissues, organs, the systems of the human body, and mechanisms responsible for homeostasis.

Includes sections on the Endocrine System, the Cardiovascular System, the Lymphatic and Immune System, the Respiratory System, the Digestive System, Nutrition, the Urinary System, the Reproductive System, and Development and Inheritance.

Seventh grade students will review the tools and mental constructs used by historians and geographers. They will develop an understanding of Ancient World History, Eras 1 – 4. Geography, civics/government, and economics content is integrated throughout the year. As a capstone, the students will conduct investigations about past and present global issues. Using significant content knowledge, research, and inquiry, they will analyze the issue and propose a plan for the future. As part of the inquiry, they compose civic, persuasive essays using reasoned arguments.

Ultimately, why something happened in the past is the question that history is all about. And here’s the fun part (or the hard part!). It’s up to you to answer the why question. You will read about many things that happened in the past and some reasons why people think they happened. People who look at the same facts sometimes come to different conclusions. Answering the other “W” questions will help you answer the question, why: Why did this happen? Answering Why -- that’s what thinking like a historian is about.

Before we can begin to study the first peoples, it is important to establish the concept of time. Historians use timelines to help aid in the understanding of the time frame in which the topic under study has taken place. The first step is to establish how the past is organized into sections of time. The organization of time into Eras is a choice made by historians. The sections of time that are being used in this book are divided by major turning points (big events that change humans forever) in history. This book is organizing the major Eras into the following four categories: Prehistory, Ancient History, Middle Ages, and Modern History.

Location, location, location. You may have heard this phrase before. It is used by realtors to explain that the most important thing in selling a house is its location. With the civilizations you are about to study, location might be the most important thing that determined the success of those civilizations.

What is an empire? How did they grow? What did they do? How did they work? Why do they decline and fall? These are some of the questions that historians have studied and tried to figure out for centuries. In this chapter you will learn about the difference between a civilization and an empire, the characteristics of empires, the impact of geography on civilizations and empires, how trade developed, and how empires were governed. Finally you will look at some examples of empires from this age.
