FORMS OF ENERGY

Heat Energy

Thermal energy is created from the vibration of atoms and molecules within substances. The faster they move, the more energy they possess and the hotter they become. Thermal energy is also called heat energy.

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.

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.

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.

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.

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.

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

Gravitational energy is a form of potential energy. It is energy associated with gravity or gravitational force – in other words, the energy held by an object.

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.

SOURCES OF ENERGY

  • Sun
  • Electric bulb
  • Explosion
  • Flame
  • Led(light emitting diode)
  • Fire
  • Moon
  • Tube light

Uses of light energy

  • It helps us to see things.
  • It helps plants to make food and grow.
  • It is used in power satellites and space stations.
  • It is used in many electronic appliances.
  • The energy of light from the sun and it  can be converted to solar energy which  can be used for domestic use

 

 

 

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.

 

 

Evaluation 

 

  1. list five sources of light energy.
  2. mention three uses of light.
  3. uses mirror and shinny surfaces to reflect light
  4. list three things that reflect light.
  5.  mention the sources of light energy
  6. discusses the uses of light
  7. identify some objects that reflect light
  8. use mirrors to form images.
