LESSON OBJECTIVE

• By the end of this lesson, the

learners

should

be

able

to

explain various forms of energy
and

ways

of

transformation

of

energy from one form to another.

WORD OF THE DAY

FORMS OF ENERGY

• The different forms of energy

include: thermal energy, chemical
energy, nuclear energy, electrical
energy, mechanical energy, sound
energy,

elastic

energy

and

gravitational energy, etc.

ACTIVITY 3

• Observe simulation and respond to the following

questions:

❖Describe what you see.

❖What do you suppose will occur when you turn

on the tap?

❖If you replace a water tap with a solar panel,

what do you suppose would happen?

❖When bicycle is used in their place, what do you

suppose will happen?

ENERGY TRANSFORMATION

• energy

transfer,

also

known

as

energy

transformation, is the transfer of energy from one
form to another.

• like in a hydroelectric power plant that transforms

the mechanical energy of water into electrical
energy.

• While energy can be transferred or transformed, the

total amount of energy does not change this is called
energy conservation.

EXAMPLES OF ENERGY TRANSFORMATION

• Friction (Kinetic energy → Heat)

• Electric heater (Electric energy → Heat)

• Photosynthesis (Electromagnetic radiation → Chemical

energy)

• Hydroelectric dams (Gravitational potential energy →

Electrical energy)

• Electric generator (Kinetic energy or Mechanical

energy → Electrical energy)

CONT’D

• Fuel cells (Chemical energy → Electrical energy)

• Battery (Chemical energy → Electrical energy)

• Fire (Chemical energy → Heat and Light)

• Electric lamp (Electrical energy → Heat and

Light)

• Microphone (Sound → Electrical energy)

• Windmills (Wind energy → Electrical energy or

Mechanical energy)
