Energy warms our homes, cooks our food, plays our music, gives us pictures on television. Energy powers machinery in factories. When we eat, our bodies transform the food into energy to do work. When we think or read or write, we are also doing work. Cars, planes, trolleys, boats and machinery also transform energy into work.
Work means moving something, lifting something, warming something, lighting something.
All these are a few of the various types of work. There are many sources of energy. In this WebQuest, we will be looking at the energy that makes our world work. Energy is an important part of our daily lives. We will also look at turbines and generators, at what electricity is, how energy is sent to users, and how we can decrease the energy we use.
