What is ESD?
Effective School Discipline (ESD) is a systems approach to enhancing the capacity of schools to educate all children by developing research-based, school-wide systems to improve school climate and create safer and more effective schools. It involves a collaborative (team-based), proactive, process to developing effective strategies for addressing inappropriate behavior that impedes successful teaching/learning.
Education for Sustainable Development The recognition of the key role of Education and Communication in enabling and enhancing sustainable development came later. Originally perceived as education about sustainability, it is being increasingly recognised, through the influence of Agenda 21 and the World Summit on Sustainable Development, as more than the dissemination of knowledge. Education at all levels can shape the world of tomorrow, equipping individuals and societies with the skills, perspectives, knowledge and values to live and work in a sustainable manner. Education for sustainable development (ESD) is a dynamic concept that utilizes all aspects of public awareness, education and training to create or enhance an understanding of the linkages among the issues of sustainable development. Education for sustainable development is a vision of education that seeks to balance human and economic well-being with cultural traditions and respect for the earth’s natural resources. ESD app
ESD stands for ElectroStatic Discharge. Static electricity is an everyday phenomenon – there can be few of us who have not experienced a static shock after walking across a room and touching the door knob, or on getting out of a car. Other static nuisance effects include the cling of some fabrics to the body, the sticking of a plastic document cover, or the attraction of dust to a TV or computer screen. While we can feel some of these effects, static electricity is normally present at lower levels that we cannot feel, hear or see, but may nevertheless damage sensitive electronic components. It can build up rapidly on objects, in unexpected ways, to produce surprisingly high voltages. People are great genrators of electrostatic charge and voltage, as shon by the common experience of electrostatic shocks we experience. (See our on-line articles on Static shocks and how to avoid them, and Why static charge builds up on people). To feel a static shock, most people need at least about 3000-
Even if you never punched, pushed, slammed or dragged your Seagate drive behind a team of horses, you could still injure it by merely touching it, if you didn’t follow correct ESD handling procedures. Simply put, you could electrocute it and never know it! The same spark that you sometimes feel and see when you touch something like a doorknob after walking across a carpet will zap your drive in the same manner as a lightning bolt would strike a tree. On this page are some fascinating bits of information which should help educate you in the knowledge and prevention of ESD problems involving your drive and computer.

By LearnESD.com Team ESD stands for Electrostatic Discharge. When two materials come into contact and then separate, static charges are developed. Electrons are transferred from one material to another material in a process called Triboelectric charging. Electrons leave their orbits around the nucleus to neighbouring orbits of another material that has a greater tendency to accept the electrons. A deficit of electrons makes the material positively charged and an excess of electrons makes the other material negatively charged.
