ELECTRICAL AND NUCLEAR ENERGY

ELECTRICAL AND NUCLEAR ENERGY

Timing

Taking into account that  that clilstore  we are going to develop in 2 hours. By this time, students already know concepts such as electrical energy, nuclear energy , biomass, solar energy geothermal energy, and others that will be reinforced in this topic. This is important because they will learn different  ways of energy and different aspects of the Power energy. Having as a basis my planning, this unit will be developed in in two sesions of 50 minutes each one.

What is energy? What are its forms ?

We use energy to power our buildings, electronics, transportation systems, and even our own bodies. Energy is the ability to do work, which happens when things are moving. Every time we feel heat, see light, hear sound, or make something change or move, energy is responsible. Energy makes possible everything that happens.

Energy can take on many different forms that scientists group into categories:

form of energy

examples of form

mechanical

water rushing through a dam

radiant

sunlight

sound

your voice, which causes air molecules to vibrate

chemical

stored in batteries, fossil fuels, and food we eat

thermal or heat

hot steam that escapes from a boiling pot

electrical

static that makes your hair stand on end on a dry day

nuclear

used in some power plants and weapons

 

be transformed into radiant energy in a light bulb, some of whose energy is lost as heat, or thermal, energy. Although it cannot be created or estroyed, energy can be stored for later, moved somewhere else, or changed into a different form.

All forms of energy can be either potential (stored) energy, or kinetic (moving) energy. Potential energy is ready to do work, whereas kinetic energy is actually doing work. Potential energy is converted into kinetic energy during the process of work being done. This conversion from potential energy to kinetic energy can occur in a variety of ways, depending on the form of energy we are using. For example, it could happen as an object falls from a height, bonds between atoms are broken, or a compressed spring expands.

WHAT ARE THE SOURCES OF ENERGY?

Energy comes from many places. Commonly used energy resources include:

source of energy

description of source

fossil fuels

coal, oil (petroleum), natural gas, and propane

biomass

plant material that is burned for its energy

geothermal energy

comes from the heat within the earth

hydropower

generated by moving water

wind

wind turns rotating machines, called turbines, to change the wind’s kinetic energy into electrical energy

nuclear energy

produced when the nuclei (center) of atoms split apart (fission) or fuse together (fusion)

solar energy

radiant energy of the Sun, often turned into electrical energy with the help of solar cells

 

 

Brainstorming activity: The teacher asks the students what they know about electrical energy and how they can use it in their homes. Then the teacher explanis to children what electrical and nuclear energy are and the way they can use both of them in their daily lives. (15’)

 

The children will have to investigate NUCLEAR ENERGY on the following videos and answer the  questions: (40’)

videos are located at the end of the page.

how does it work 1-3

 

 

Activities

 

1.- What things use electrical energy? Make a circle.

 

an aeroplane     a computer       a fireplace          a car                     a gas stove

 

a refrigerator                    a radio                  a T.V. a bike.

 

2.- Write true or false:

__ Nuclear energy is used in nuclear power stations to generate coal.

__ One of the laws of universe is that matter can be created and destroyed.

__ Matter can be changed into energy

__ For the ancient Greeks the smallest part of nature is an atom.

__ Atoms are made of a nucleus of protons and neutrons, surrounded by electrons.

__ Albert Einstein explained that matter could be changed into energy.

3.-Brainstorm with students some of the opportunities and challenges they see for using nuclear energy as an energy source. After

the class has come up with a list, then read the Advantages and Challenges of Nuclear Energy section of the informational text.

Discuss both lists. Are there some items that are more important or meaningful than others? Why? What would you need to take into

consideration if you were to decide whether or not a new nuclear plant should be built?

3.- Assign pairs or small groups of students different roles to take. Explain to students that a Combined Construction Permit and Operating

License is one of the first steps to building a new nuclear power plant. In this stage, the Nuclear Regulatory Commission is open to hearing

information on three issues: environmental protection, plant safety, and emergency procedures. In this mock hearing, economic issues will

also be discussed.
