That’s lightning! It is an electrical discharge between positive and negative regions of a thunderstorm. It was once only magical, mysterious, and misunderstood. However, we know much more about it today. Yet, for children, it is still magical and mysterious. Students’ will decide what they want to learn about lightning, how to go about finding their answers, and deciding what skills they need to further study some of their questions. Using Newton’s Apple show #1513 LEARNING OBJECTIVES Students will: Build a knowledge of lightning and static electricity through video, hands-on demonstrations, the Internet, the library, and a guest speaker. Define and understand these vocabulary words: static electricity, charge, electrons, negative charge, positive charge, neutral charge, supersonic, conductor, insulator, attract, repel.

See Also: Small Business and Environmental Assistance Education K-12 Air Lesson Plans Waste Lesson Plans ... TES 1999 Lesson Plans Conserving Electricity: Turn It Off Purpose To discuss how electricity causes air pollution. Grade level Second Grade Essential Elements Classify, order, and sequence data. The student shall be given opportunities to: (B) classify matter and forces, organisms, actions, and events from the environment according to similarities and differences. Objective To understand why saving energy helps stop air pollution. Focus Walk over and turn the lights off, then tell the class that you are helping to stop air pollution. Then tell the class that since we need the lights right now, you will turn them back on. Materials None Background Most of our electricity is produced in steam turbines. A power source, such as coal, gas, or oil, heats water in a boiler to produce hot, high-pressure steam. This steam expands against the blades of a turbine. A turbine is a device that spins when air or water is forced against it. You can think of it as a kind of enclosed windmill. The hot, expanding steam forces the turbine to spin. The spinning turbine then operates a generator that produces electricity. Procedure Tell the class you are going to tell a story about a wise old owl and his young pupil. Warn them that the story ends with a question that you will hope they will be able to answer.

77. Ride The Wind!TM lesson Plan Ride the Wind!TM education resource site TM program, which utilizes wind energy to supply electricity to the Ctrain system of Calgary http://www.re-energy.ca/ridethewind/lesson_plan.shtml

Lesson Plan: Ride the Wind! TM education resource site Energy Transformations This activity investigates the nature of several important energy transformations that can be observed as wind energy is captured and converted to electricity for the commercial market. It assumes that you have introduced the concept of energy transformations, but extends and applies this concept to renewable energy and public transit. Curriculum Ties This activity addresses learning outcomes in: Science 8 (2001 vers.) Unit D: Mechanical Systems Science 9 (1990 vers.) Unit 3: Heat Energy: Transfer and Conservation Science 9 (1990 vers.) Unit 4: Electromagnetism Concepts Energy is easily converted from one form to another. Earth's surface winds are a viable source of electrical energy. Renewable energy from sources such as wind can help reduce air pollution. Learning Outcomes On the completion of this activity, students will: Describe several transformations of energy as wind is converted to electricity for use in powering Calgary's light rail transit system; Use the analysis of energy transformations to identify ways to improve the efficiency of mechanical / electrical systems.

Do It Yourself: Energy Transfer Lesson Plan This is an outline in classic lesson plan format detailing our first Energy Outreach. It covers the 5th Grade level Sunshine State Standard for energy while building a solid foundation to build upon for later lessons. Objective: Illustrate that energy can be transferred to one type of energy to another with varying degrees of efficiency; Energy is defined as the ability to do work; Different types of energy are heat, light, radiation, chemical, mechanical, and electrical. Materials: Tesla coil, plasma ball, laser, radiometer, light source, thionen solution, incandescent bulb, fluorescent bulb. Introduction: KWL with students to determine their knowledge on these types of energy. Have students get into groups of 3-6 and make a list of various types of energy that they know of. What are some of the energy types your group listed? List types on the board. Make sure that heat, light, radiation, chemical, mechanical, and electrical are listed. Also explain that some types are radiant energy like heat, light, magnetic, and nuclear energy. Let's see if we can transfer these types of energy from one type to another.
