ENTRY BEHAVIOUR/ PREVIOUS KNOWLEDGE: the students have been taught Pest and Diseases of crop plant.

WORD FILE: colourless, odourless, tasteless.                  

             LESSON CONTENT

                        WATER                              

Water is a clearly colourless, odourless and tasteless liquid.

Water is needed by all living things to survive. 70% of Human weight is made by water.

                         EVAPORATION

Evaporation is the process when liquid substance changes into Vapour (gas).

Water and every other liquid substance evaporates when heated, it gradually turns into gas (vapour) and escapes into the atmosphere.

Note: water in it gaseous form is called steam.

FORMS OF WATER

Water is can be in the following forms.

  1. Solid form e.g. Ice
  2. Liquid form e.g.  Water
  3. Gas form e.g. steam

WAYS IN WHICH WATER EVAPORATES

  1. When water inside an open container is been heated by fire or sun, the water gradually disappears into vapour.
  2. Water evaporate from our body through sweating.
  3. Water evaporates from rivers, ponds, streams when heated by the sun.

HOW WIND CAUSES EVAPOURATION (EXPERIMENT)

Wind causes evaporation because

  1. Our clothes dry faster when we experience a windy day.

So wind causes evapouration also.

CONDENSATION

Condensation occurs when water vapour changes back to water due to the contact with a   cooler surface.

WAYS BY WHICH CONDENSATION TAKES PLACE

  1. Water vapour condenses on a cold glass by placing a kettle of water on electric cooker and used the cold glass to block the vapour of the water during heating, the vapour will fall back as water to any available container.

                          FREEZING

Freezing is the withdrawal of heat to change something from a liquid to a solid.

Freezing is the state when Water changes from liquid into solid form.

The electrical device that turn water from it liquid form into solid form is called A FREEZER.

                  SOURCES OF WATER

Water can be gotten from natural sources and man – made sources.

NATURAL SOURCES OF WATER

  1. Spring water
  2. Rain water
  3. River
  4. Lake
  5. Sea
  6. Ocean

MAN MADE OR ARTIFICIAL SOURCES OF WATER

  1. Bore –hole
  2. Irrigation
  3. Pipe- borne water
  4. Dam

     USES OF WATER

The following are some ways we make use of water.

  1. Domestic purpose such as washing, bathing, drinking, flower wetting, cooking.
  2. Transportation purposes: ships. Boats, canoes moves on water.
  3. Industrial uses: used for cooling machines, for mixing chemicals, washing equipment.
  4. Agricultural purposes: crops and animal needs water to survive.
  5. It used to aid our digestive system.

INSTRUCTIONAL PROCEDURE

  • The Teacher revises the previous lesson (Pest and Diseases of crop plant).
  • The Teacher introduces the lesson through question and answer (WATER).
  • The Teacher explains the lessons.
  • The Teacher write the note on the board.

LEARNERS ACTIVITIES

Learners participate in the class discussion

LESSON EVALUATION

Teacher ask the learners to:

  1. Define and explain evaporation
  2. Define and explain condensation
  3. Mention three importance of water

CONCLUSION: the teacher summarize the lesson.
