Water and its uses

Activity:

The personal use of water

[lo 1.2]

Write down all the activities in which you use water during a single day. Compare it with what your classmates have written. Ask your parents to show you how the water meter at your house works.

The advantage of running water in the home [lo 3.2]

Study the pictures to help you to describe the ways in which running water in the home makes life easier.

The uses of water

Paste appropriate pictures of water below each section.

  1. For cooking food, for cleaning and drinking.
  2. For cultivating food.
  3. For transport and recreation.
  4. For cleaning.
  5. For plants and animals to live in.
  6. For factories, industries and power stations.

Assessment

LEARNING OUTCOME 1: SCIENTIFIC INVESTIGATIONSThe learner will be able to act confidently on curiosity about natural phenomena, and to investigate relationships and solve problems in scientific, technological and environmental contexts.

Assessment standards: we know this when the learner

  • takes the lead in investigating and collecting data;

LEARNING OUTCOME 3: SCIENCE, SOCIETY AND THE ENVIRONMENTThe learner will be able to demonstrate an understanding of the interrelationships between science and technology, society and the environment.

ASSESSMENT STANDARDS: WE KNOW THIS WHEN THE LEARNER

  • understands the impact of Science and Technology.

Memorandum

The ways in which having running water in the home makes life easier.

  • We can bath or shower without first having to fetch water.
  • We do not have to fetch water to wash dishes.
  • Having running water in the home saves time and energy.
  • Laundry can be washed easily, our hands are not exposed to the chemicals in soap powders (if you have washing machine!)
  • It is easier to keep everything clean and neat.
  • We can have flush toilets, so we merely pull a chain and everything remains clean and free of germs.
  • We merely have to turn the tap to be able to wash vegetables before eating or cooking them.
  • We have drinking water available all the time.

It is easy to bath and take care of pets if we have clean water.
