What Is Energy Reading for 6th Grade

Summary

With an introduction to the ideas of energy, students discuss specific energy types and practical energy sources. Associated hands-on activities help them identify energy types in their surroundings and enhance their understanding of the concept of energy.

This technology curriculum aligns to Next Generation Scientific discipline Standards (NGSS).

Applied science Connection

Nosotros use energy in all its forms almost every day. Engineers study these forms of free energy to help create things that brand our lives easier. Currently, engineers are looking for ameliorate ways to produce electricity to go on energy affordable and less destructive to the environment. They are likewise investigating alternative fuel sources for use in vehicles, such as biofuels from algae and hydrogen from h2o.

Learning Objectives

Afterwards this lesson, students should be able to:

• Define free energy and identify the different types that exist.
• Define potential and kinetic energy.
• Relate specific energy types to dissimilar engineering projects.
• Describe the role of technology in finding and testing various energy sources for electricity product.

Introduction/Motivation

You lot cannot e'er see energy, touch information technology or hold it in your hand, just energy is everywhere.

Free energy is the power to exercise work, to make things happen and to cause changes. Energy cannot be made or destroyed; information technology can only be changed into unlike forms. Can yous name a grade of energy? (Examples: Calorie-free, heat, electricity, audio.) From where do you think nosotros get electricity? (Possible answers: Power institute, the outlet in the wall, food.) Can you think of an example in which free energy is changed from one class to another? How almost a calorie-free bulb? We turn information technology on past plugging information technology into the wall. What happens when you exit a light bulb on for a while? Information technology gets hot! Well, that is an example of electrical energy changing into oestrus energy from the vibration of the filament, as well as producing light!

At present, let's remember about a gas-fueled electricity plant. A power plant produces electricity by irresolute the chemical energy in fuel into electrical energy. Showtime, gas is burned within the institute, converting its chemical energy into estrus. Next, the oestrus turns h2o into steam, which moves a turbine motor or generator. Finally, the generator produces electricity.

This steam-based engineering science was showtime discovered in the early 1700s when engineers began to figure out means to use the free energy in steam released by boiling water. They developed engines that converted steam energy into mechanical free energy for use in farm and factory machinery, and later for trains and cars. Historians often cite the evolution of the steam engine equally the kickoff of a period in modern history called the industrial revolution.

We classify free energy in ii means. Showtime is potential energy, which is the amount of energy something has stored within it. Anything tin have potential free energy. A battery has potential energy stored by a difference in ionic concentration; even you have potential free energy, as you lot sit in your chair. How much potential energy you accept depends on a few things, including how loftier up yous are and how large you are. Side by side is kinetic energy. Kinetic free energy is the energy of an object in motion. Annihilation that is moving has kinetic energy. Mechanical objects, such as a clock or a person on a skateboard, have kinetic energy, merely and then do lite, sound, wind and water. Can you come across examples of free energy around the classroom? Well, today we are going to find some of these examples and learn near how engineers work with dissimilar types of free energy.

Write the following phrases on the board and discuss with the course.

What is energy?

• The ability to do work or cause change.
• Work is the awarding of a force through a distance. (Inquire students for examples, such as moving a box across the room, sweeping, etc.)

Strength can put matter into movement or cease it if information technology is already moving.

Motion is a change in position of an object with time.

• To do work, energy is needed.

From where does energy come?

• Natural energy sources: food, water, plants, trees, gravity, sun, fossil fuels, uranium, plutonium
• Ways that humans have harnessed or converted natural energy sources: hydroelectric dams, coal/oil power plants, nuclear ability plants, current of air turbines, solar panels, etc.

What are different types of energy? (Run across the Vocabulary/Definitions section.)

• Kinetic energy: electrical, light, thermal, solar, sound, wind, hydro
• Potential energy: chemic, mechanical, nuclear, gravitational

How do we apply energy?

• To break down and digest nutrient (in our bodies)
• To heat houses and other buildings
• To illuminate lights
• To ability televisions, phones, games, cars
• To run computers and appliances

Lesson Background and Concepts for Teachers

Energy takes many forms. Thermal energy (or rut) boils water, keeps the states warm and drives engines. Chemical energy fuels automobiles and airplanes. Electric energy drives many small machines and keeps lights glowing. Nigh every form of energy tin be converted into other forms. But any form it is in, energy is substantially the chapters for making something happen or, every bit engineers and scientists say, "doing piece of work."

Virtually all our free energy comes to us ultimately from the sun (see Effigy 1). Nosotros get some energy directly via passive solar lighting and heating, or solar ability cells. However, most energy comes indirectly via burning fossil fuels (coal, oil and gas), which received their energy from fossilized plants and other organisms. The plants and organisms originally obtained their energy direct from the sun past a process called photosynthesis. Some of these sources of free energy are renewable and others nonrenewable or limited in their available quantity.

Lesson Closure

Today we started learning about energy and engineering science. Can you define and draw the word "energy?" What types of energy can you meet, feel or hear? (Possible answers: Heat, light, audio, motility.) Why would an engineer care about energy? (Reply: Engineers develop products that use energy. Engineers help develop ways to store energy for our use.)

Assign students the Energy Vocabulary Quiz to gauge their mastery in agreement the uses of energy in their surroundings and the fundamental types of energy.

Vocabulary/Definitions

biomass energy: An energy resources derived from organic matter. Many people use biomass energy to heat their homes; they burn forest. Many agronomical crops are besides biomass. For instance, corn can be fermented to produce ethanol that is burned as a liquid fuel. Wood is a renewable energy source as long as cut trees are replaced immediately.

chemic energy: The energy stored on the chemical bonds of molecules that it released during a chemical reaction. Chemical energy holds molecules together and keeps them from moving autonomously. For instance, a car engine uses chemical energy stored in gasoline, and moving people apply chemical energy from nutrient.

electrical free energy: Electrical energy exists when charged particles attract or repel each other. Television receiver sets, computers and refrigerators use electrical energy.

free energy: The ability to practise piece of work.

kinetic energy: The energy of motion. For example, a spinning top, a falling object and a rolling ball all accept kinetic energy. The move, if resisted by a force, does work. Current of air and h2o both have kinetic free energy.

calorie-free energy: Visible lite free energy, such as from a calorie-free bulb or fireflies or stars, is just one class of electromagnetic free energy. Others forms include infrared and ultraviolet light.

mechanical energy: Mechanical free energy is energy that tin be used to do piece of work. It is the sum of an object's kinetic and potential energy.

nonrenewable free energy: Free energy from sources that are used faster than they can be created. Sources include oil (petroleum), natural gas, coal and uranium (nuclear).

nuclear energy: Nuclear free energy is the energy found inside the nucleus of atoms and can only be released when atoms are dissever. Some ability companies that supply homes, schools and buildings with electricity use nuclear free energy to generate electricity.

potential energy: Potential energy is the energy stored by an object as a result of its position. A roller coaster at the top of a hill has potential free energy.

renewable energy: Energy that is made from sources that tin be regenerated. Sources include solar, wind, geothermal, biomass, ocean and hydro (water).

sound energy: Audible energy that is released when yous talk, play musical instruments or slam a door.

thermal energy: Heat energy produced when the molecules of a substance vibrate. The more rut a substance has, the more rapid the vibration of its molecules. Heat energy flows from places of higher temperature to places of lower temperature.

Assessment

Pre-Lesson Assessment

Discussion: Ask students the following questions:

• What is energy? (Possible answers: The power to do piece of work or crusade change and the capacity for vigorous activity. Work is the application of a force through a distance [inquire for examples]. Force can put matter into motion or stop it if it is already moving. Motility is a alter in position of an object with time. To practise work, energy is needed.)
• From where does energy come? (Answers: Ability plants, people, food, light, windmills, turbines, fires, etc.)
• What are different types of free energy? (Answers: Chemical, thermal, mechanical, potential, kinetic, solar, audio, nuclear, etc. [see the Vocabulary / Definitions section].)
• How practice we use energy? (Possible answers: Our bodies apply energy to break down and assimilate food. We employ energy to heat houses and buildings, to plough on lights, to power televisions, radios, cars, computers, appliances, etc. Sound energy is used in communication and to notice fish in the ocean!)

Postal service-Introduction Cess

Accept-Home Definitions: Ask students to enquire several members of their families for definitions of a specific free energy form, and then look upwardly the definition in the dictionary. Have them write down comparisons of these definitions and a reason why each might be different. Share these explanations with the class.

Lesson Summary Assessment

Energy Identifier: Bring to form examples or images of the following objects. Accept students identify the type of energy that is related to each detail and the free energy transfer that occurs. You could set upwardly stations around the room or turn information technology into a game in which the students earn points for each blazon of energy correctly identified.
