MEANING OF ENERGY

Energy is the ability to do work.

SOURCE OF ENERGY

  • Cooking
  • Heating
  • Technology
  • Transportation

FORMS OF ENERGY

Heat Energy

Heat energy is the type of energy that can be used for ironing our clothes . Heat energy that is generated by burning charcoal can be used for roasting plantain , fish or meat (SUYA) . Heat energy can also be used for ironing our clothes . This type of heat energy that is used to iron clothes is generated by electricity . In Europe , houses are warmed up by heat generated by coal

Chemical Energy

Chemical energy is stored in the bonds of atoms and molecules – it is the energy that holds these particles together. Stored chemical energy is found in food, biomass, petroleum, and natural gas. When food is eaten , energy that are stored in food as nutrients are released into the body for day to day activities . That is why we do not have enough power or energy if we do not eat well or if we do not eat at all .

Nuclear Energy

Nuclear energy is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission). Nuclear power plants split the nuclei of uranium atoms to produce electricity. Nuclear energy can also be gathered together to make nuclear bombs although leaders of so many nations are against this because of the enormous damage that nuclear bomb can cause to living things

Electrical Energy

Electrical energy is the movement of electrons (the tiny particles that make up atoms, along with protons and neutrons). Electrons that move through a wire are called electricity. Lightning is another example of electrical energy. Electrical energy is used to power most of our electronics like television , radio, mobile phones and washing machines at home .

Radiant Energy

Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Examples include the energy from the sun, x-rays and radio waves.

Light Energy

Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object’s atoms heat up. Light travels in waves and is the only form of energy visible to the human eye. We use light to see . We use light to make photo copies of documents , Plants make use of sunlight to manufacture their own food. This process is known as PHOTOSYNTHESIS

Motion Energy

Motion energy – or mechanical energy – is the energy stored in objects; as objects move faster, more energy is stored. Examples of motion energy include wind, a flowing river, a moving car, or a person running.

Sound Energy

Sound energy is the movement of energy through substances. It moves in waves and is produced when a force makes an object or substance vibrate. When solid objects move , they generate sounds as they vibrate . We can hear sounds because of the ear drums in our hear. Sound energy helps in the production or arrangement of sounds which are pleasant to hear which is known as music .

Elastic Energy

Elastic energy is a form of potential energy which is stored in an elastic object – such as a coiled spring or a stretched elastic band.

Gravitational Energy

Any object that is thrown up will definitely come down . The force of gravity is the force of the earth pull. It is the force of gravity that pull any object that is thrown up back to the earth . When an apple is thrown up , it will fall back to the earth . If a stone is stone up , it will fall back to earth . this is made possible because of the force of gravity

 

Presentation :

The topic is presented step by step

 

Step 1:

The class teacher revises the previous topics

 

Step 2.

He introduces the new topic

 

Step 3:

The class teacher allows the pupils to give their own examples and he corrects them when the needs arise

 

 

Conclusion

The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she does the necessary corrections when and where  the needs arise.
