Access to water supply and basic sanitation systems is an essential human need. In order for our society to function efficiently and in a safe environment, it is important that these basic needs are met. Plumbers and professionals working in the plumbing industry help us to achieve this goal. A modern-day plumber's job is wide in scope: plumbers lay down pipes for the distribution of water and disposal of wastewater; design, repair, and maintain the drain, waste, and vent systems; install fixtures, and also work with gas pipelines. This free online course will introduce the learner to the plumbing profession. The course looks into the history of plumbing from the ancient to the modern times. It also highlights the importance of safety procedures in the profession. Under plumbing safety, the course covers personal protective equipment, hazard communication, and the safety guidelines that a plumber should follow when working in trenches and confined spaces. This course, the first in the series on plumbing, will be of great interest to construction professionals who want to learn what plumbing is and the skills that are needed to advance in this specialized field. It will also be of interest to all learners who want to enter this trade and need an understanding of the profession, its terminologies, and the associated health and safety facts.<br />

Introduction to Plumbing Pipes and Fixtures is a free online vocational course designed for anyone wanting to learn more about plumbing. This course is the third in the series of plumbing courses. While the first two introduced the learner to the trade and plumbing tools and drawings, this course goes a step further. For a building to be considered habitable, it has to be connected to the main water and gas supply systems, and have appropriate provisions for handling waste water. The installation of long-lasting plumbing pipes ensures that these basic requirements are met. In this free online course, various materials such as plastic, copper, cast iron, carbon steel, and CSST that are used to make pipes and fixtures are discussed. Besides this, the course covers the terms associated with plumbing pipes, the differences between fittings and valves, the tests carried out on plumbing and gas pipes to ensure they are leak-proof, and the basic principles of sanitation and safety. This course will be of great interest to construction professionals who want to deepen their existing knowledge on plumbing: identify the properties as well as the advantages and the disadvantages of working with different piping materials. It will also be of interest to all learners who want to learn about the different types of pipes and fixtures that are in use today.<br />

The plumbing profession places both physical and intellectual demands on plumbers. While the physical aspects of the job such as using tools to install and maintain plumbing systems are clearly visible, the intellectual requirements of the trade are skills that are used in the background. Performing basic math calculations and reading plumbing drawings are examples of such intellectual tasks. This free online course in plumbing introduces the learner to the wide array of tools used by plumbers in the trade. These tools range from measuring and layout tools to those used for leveling, cutting, and assembling pipes and fittings. The course also covers topics on basic math and plumbing drawings, which include basic math skills essential for plumbers to calculate pipe measurements, and how to read construction drawings, how to identify the components that make up these drawings and the types of plumbing drawings a professional in this field will have to read and interpret. This course will be of great interest to all professionals who want a deeper knowledge and understanding of plumbing tools and drawings. It will also be of interest to those learners who have completed the first course on plumbing and would like to build upon that knowledge by doing the next course in the series.<br />

This course is intended as an introduction to political philosophy as seen through an examination of some of the major texts and thinkers of the Western political tradition. Three broad themes that are central to understanding political life are focused upon: the polis experience (Plato, Aristotle), the sovereign state (Machiavelli, Hobbes), constitutional government (Locke), and democracy (Rousseau, Tocqueville). The way in which different political philosophies have given expression to various forms of political institutions and our ways of life are examined throughout the course.

This course examines major texts in the history of political thought and the questions they raise about the design of the political and social order. It considers the ways in which thinkers have responded to the particular political problems of their day, and the ways in which they contribute to a broader conversation about human goods and needs, justice, democracy, and the proper relationship of the individual to the state. One aim will be to understand the strengths and weaknesses of various regimes and philosophical approaches in order to gain a critical perspective on our own. Thinkers include Plato, Aristotle, Machiavelli, Hobbes, Locke, Rousseau, Marx, and Tocqueville.
