  1. Electricity: The invisible Genie 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 Can you tell where the genie is at work in your home? Do you know which professionals specialize in designing and making devices and machines to produce and use electricity better? Electrical and Electronics Engineers

  2. Electricity: The invisible Genie What is electricity? • 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. Where does electricity come form? • 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) Have you tried making electricity yourself?

  3. DEVICES AND TOOLS THAT ALLOW CREATION OF ELECTRICITY: MAGNETS and COILS MOVING NEAR EACH OTHER AND PULLING ELECTRONS INTO WIRE CIRCUITS SPECIAL CHEMICAL REACTIONS UNBALANCING ELECTRONS IN BATTERIES and FUEL CELLS DEVICES AND TOOLS THAT ALLOW THE USE OF ELECTRICITY: RESISTORS and THERMAL ELEMENTS FOR HEATING RESISTORS and LIGHT-EMITTING ELEMENTS FOR ILLUMINATION ELECTROMAGNETIC COILS and ELECTRIC MOTORS FOR FANS AND ROTATING TOOLS MOTORS and HYDRAULIC COMPRESSORS FOR COOLING AND REFRIGERATION MOTORS and SOLENOIDS FOR HYDRAULIC COMPRESSORS AND TRANSPORTATION ELECTROMAGNETIC DEVICES FOR CODING INFORMATION, COMMUNICATIONS , DATA PROCESSING, PRESENTATION AND STORAGE

  4. A Long Time Ago, We lived like this - because we had not learned how to make and use electricity.Can you tell what was different then?

  5. STEM LEARNING ABOUT ENGINEERING AND ELECTRICITY IN SCHOOL: 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. TECHNOLOGY ENGINEERING COMMON CORE? SCIENCE MATHEMATICS
