1 Electricity brings to us energy, quietly and cleanly, virtually Instantly, anywhere and in practically unlimited amounts from far and close places, to help make our lives better:  To make and keep places lighted  To make and keep places and food hot or cold  Help us do work that needs force and movement  Help us collect, create, manage and display data as information and ideas, such as text, numbers, voice sound, music, video, animations and intelligent controls

2  Electricity is the movement of energy carried by excited electrons, mostly in conductive (conductor) materials. Electricity moves very fast, and can be very strong. The electrons in electricity always carry companion (electro)static and (electro)magnetic fields around them. Electricity or electric energy can be produced by exciting the electrons in materials, when doing things like:  rubbing materials against each other (surfaces)  inducing electrons using magnetic fields (magnets)  bumping electrons out of their atoms using sun light rays (photons) or special chemical reactions (in fuel cells)

5 TECHNOLOGY SCIENCE MATHEMATICS ENGINEERING COMMON CORE? The purpose of the California State education Common Core k-12 Curriculum Standards (CCSS) is to ensure a good understanding of concrete and abstract ideas related to science, technology, engineering and mathematics in our classrooms. Learning is hoped to focus into fewer, but central and coherently related topics in the quantitative subjects, which include teaching and learning about electricity. The standards aim to promoting embracing and mastering the concepts, rather than memorizing routines mindlessly. For this, teaching is suggested to include more hands-on experiences, focused on core, useful real life things and activities. LEARNING ABOUT ENGINEERING AND ELECTRICITY IN SCHOOL:
