Overview : Electricity is all around us–powering technology like our cell phones, computers, lights, soldering irons, and air conditioners. It’s tough to escape it in our modern world. Even when you try to escape electricity, it’s still at work throughout nature, from the lightning in a thunderstorm to the synapses inside our body. But what exactly is electricity? Definition Electricity is simply put the movement or flow of electrons from one atom to another. Going Atomic To understand what electricity really is, we must go down to the very basic building block of matter ----- down to the atomic level. Here's the Bohr's Atomic Model to illustrate the fundamental components of an atom. An atom has three basic particles namely the electron, proton and neutron. Electron - is negatively charged particle ( - ) Proton - is positively charged particle ( + ) Neutron - has no charged Electron Flow "What makes an electric...

Electricity has been one of the major asset of human civilization. Electricity is the physical flow of electrons also referred to as an electric current. It exist in the nature; however, it took many years before human fully understood its immense power and its nature. In this lesson, students will learn the fundamental nature of electricity and how it works. The students will also learn the Ohm's Law and lastly the application of electricity.

Name the critical part of the atom re...

Electromagnetic induction (or sometimes just induction) is a process where a conductor placed in a changing magnetic field (or a conductor moving through a stationary magnetic field) causes the production of a voltage across the conductor. This process of electromagnetic induction, in turn, causes an electrical current - it is said to induce the current. Electromagnetic induction is an incredibly useful phenomenon with a wide variety of applications. Induction is used in power generation and power transmission, and it's worth taking a look at how that's done An electric generator A commercial-type diesel generator An electric motor is a device for transforming electrical energy into mechanical energy; an electric generator does the reverse, using mechanical energy to generate electricity . At the heart of both motors and generators is a wire coil in a magnetic field. In fact, the same device can be used as a motor or a generator. AC and DC Generator Both AC and D...

        Many useful devices are built using the principle of  electromagnetic induction. Two of the most important devices that use this principle are the generator and transformer . This lesson is designed to help students understand the fundamental application of electromagnetic induction. OBJECTIVES :   Given varied activities, students, with 80% proficiency will be able to:      a. Explain how an electric generator and transformer work.      b. Illustrate a model of generator and transformer.      c. Give the importance of generator and transformer to human advancement.

                      Students often find physics to be challenging, however, this set of hands-on activities allows students to explore Isaac Newton's Laws of Motion in a fun, problem-solving atmosphere. Students will learn about Isaac Newton, complete a set of hands-on activities and then discuss what they learned as a class. Lesson Objectives Students will be able to: Identify which of Newton's Laws is being represented Give an example of a scenario that represents one of the three laws State each of Newton's Three Laws of Motion Procedure In this lesson plan, students will do the following: Briefly discuss what they know about Isaac Newton Read about Newton's Three Laws of Motion Complete stations that show each of Newton's Three Laws of Motion Discuss which law was represented at each station Begin by asking students if they've ever heard of Isaac Newton. On the board, write down everything th...

        S cience has become an important component in the K–12 curriculum. As the twentieth century ended, it was clear that science and technology played significant roles in the lives of all people, including future employment and careers, the formulation of societal decisions, general problem solving and reasoning, and the increase of economic productivity. There is consensus that science and technology are central to living, working, leisure, international competitiveness, and resolution of personal and societal problems.  Being a science educator is a priceless experience. Yet it is a very challenging and taxing job. As a teacher you have to be prepared always the moment you enter the classroom. This website aims to help teachers prepare lesson plans and science experiments activity. The lesson plans and activities are tailored to meet the needs of learners inside the classroom.                   To all tea...
