This module is developed for High school students . This module is about water pollution, its types and its effect on health and environment.

This online textbook is intended for, but not limited to, 14 to 18 year old teenagers who have a general interest in mathematics. The text's language is aimed at high school students without a rigorous understanding and knowledge of university-level mathematics.

This book introduces several interesting topics not covered in the standard high school curriculum of most countries.

The materials presented can be challenging, but at the same time, we strive to make this book readable to all with 9–10 years of formal education.

Geology can roughly be divided into physical geology, which studies the materials of the Earth and the processes operating in it, and historical geology, which aims at a reconstruction of the history of the Earth. Historical geology requires some knowledge of physical geology for its elucidation. (Imagine, by way of analogy, forensic scientists diagnosing cause of death as a gunshot wound, which is a historical question. It would obviously be necessary for them to know something about the behavior of guns, which would be a physical question.) However, the aim of historical geology is to understand the past, and knowledge of physical geology is merely an adjunct to this aim.

Building a computer can be a very rewarding experience. Since you’re reading this, you’re probably thinking about building your next computer instead of buying one pre-built. This is a very viable option these days and can bring many benefits; you can learn a lot about computer hardware by building one, you get a totally personalized computer, you can choose better components and you may be able to save some money and have fun. Additionally, if you are the sort of person who wants to understand how things work, if you take broken stuff apart just to see how it all fits together, if you have a drawer somewhere full of “parts” you think may come in handy someday, then you just may be in the right place.

Physiology The word physiology is from the Ancient Greek φυσιολογία (phusiología, "natural philosophy") and it is the study of how organisms perform their vital functions. An example is the study of how a muscle contracts or the force contracting muscles exert on the skeleton. It was introduced by French physician Jean Fernery in 1552. Physiology is built upon a tripod of sciences: physics, chemistry, and anatomy.

This is a guide to HTML, a standard markup language for web pages. A text editor and a web browser is all you need to create web pages, view your handiwork, and share information with others all over the world.

This book covers simple HTML syntax. For dynamic behavior in websites, see the JavaScript wikibook. Another separate book covers Cascading Style Sheets (CSS) which handle overall look and styling, but the present book addresses CSS briefly. Additionally, XHTML has its own textbook.

This webpage lists intermediate-level conversational phrases and terms. The terms are listed in Arabic, transliteration, and English translation. The more difficult terms are presented with brief commentary to supply context. The listed terms and phrases include words conducive to beginning and sustaining fairly complex and wide-ranging conversations.

Dear student! You are starting to learn about computation and its purpose. This course covers the same materials as an introductory class for undergraduate computer science majors. Its curriculum, which includes software, hardware and algorithms, resembles that of a one- or two-semester first-year college course or the high school Advanced Placement (AP) Computer Science. It does not require a formal computer science background.

Library and Information Science (LIS) is the academic and professional study of how information and information carriers are produced, disseminated, discovered, evaluated, selected, acquired, used, organized, maintained, and managed. This book intends to introduce the reader to fundamental concerns and emerging conversations in the field of library and information science.

A secondary goal of this book is to introduce readers to prominent writers, articles, and books within the field of library science. The book originated as a collection of annotations of important LIS articles. Though these citations are being developed into a fuller text, we hope that this book remains firmly rooted in the literature of LIS and related fields, and helps direct readers toward important resources when a particular topic strikes their fancy.

Introduction to Paleoanthropology covers the various species and subspecies that gave rise to human beings. Paleoanthropology is a subdiscipline of physical anthropology that focuses on the fossil record of humans and non-human primates.

Sociology is the study of human social life. Human social life is complex and encompasses many facets of the human experience. Because of the complexity, the discipline of sociology subdivided over time into specialty areas. The first section of this book covers the foundations of sociology, including an introduction to the discipline, the methods of study, and some of the dominant theoretical perspectives. The remaining chapters focus on the different areas of study in sociology.

Introduction to Sociology is a featured book on Wikibooks because it contains substantial content, it is well-formatted, and the Wikibooks community has decided to feature it on the main page or in other places. Note: See "Instructor Resources" to find a list of Course Adoptions and accompanying PPTs.

The end goal of this project is to create an online resource for those wishing to learn Japanese. We will attempt to encompass all aspects of the Japanese language, including pronunciation, reading, writing, and grammar.

This book is a guide to JavaScript, a scripting language widely used in web pages and web applications such as email applications. JavaScript is not to be confused with Java, which is quite a separate language for creating stand-alone applications.

Knoppix is an astoundingly clever product. It runs Linux completely from a CD or DVD. There is no need to install. It bypasses all the software already installed on your PC or laptop and automatically detects the hardware in your computer (subject to suitable hardware). When you've finished using Knoppix, simply restart. Your computer will return to your regular system, and it will behave as if nothing has happened. Knoppix is Free Software and open source under the terms of the GNU General Public Licence (GPL).

TeX is a computer program for typesetting documents, created by Donald Knuth. It takes a suitably prepared computer file and converts it to a form which may be printed on many kinds of printers, including dot-matrix printers, laser printers and high-resolution typesetting machines. LaTeX is a set of macros for TeX that aims at reducing the user's task to the sole role of writing the content, LaTeX taking care of all the formatting process. A number of well-established publishers now use TeX or LaTeX to typeset books and mathematical journals. It is also well appreciated by users caring about typography, consistent formatting, efficient collaborative writing and open formats.This is a guide to the LaTeX markup language. It is intended to form a useful resource for everybody from new users who wish to learn, to old hands who need a quick reference.

This is an elementary Latin course accompanied with a detailed grammar based upon Kennedy's Public School Latin Grammar designed to introduce one to the world of classical languages. A basic understanding of grammatical terminology would be helpful; however, it is not required. Basic definitions of terms will be explained in Lessons 1 and 2, and later elaborated as needed.

It is often remarked that groups are everywhere, whether in our social lives, our work lives, or even our families. In each of these situations, sets of individuals decide to work collectively to achieve particular goals.

However, although groups are everywhere and we participate in them constantly, we do not understand them very well. Many of us can tell stories of groups that seemed perfect for a given task, but which failed. And we all have reasons (or excuses) that explain such failures.

But our experiences in groups suffer precisely because we are with them.

The study of groups as a phenomenon that is unique and different from other social phenomena is very active, reflecting both the importance it has and how much we still don't know about groups.

Miskitu Aisas! ("Speak Miskito!"), a language course in Wikibooks, is an elementary introduction to the Miskito language, spoken in parts of Nicaragua and Honduras. The course focuses primarily on presenting the grammar basics through carefully graded and didactically presented lessons. Miskitu Aisas! assumes no prior knowledge of the language and no specialised knowledge of linguistics, although at least a general background in "school grammar" will no doubt be helpful, as will any previous experience at learning foreign languages.

A concise approach to New Zealand History, this textbook covers the first inhabitants, the Maori, the discovery of New Zealand by the Europeans and some of the significant events that have led up to the way the country is in the present day.
