3. Why do you think some people still spend time lying in the sun to become tanned?

  1. Write a letter to the principal of your school in which you offer suggestions for protecting the learners at the school against sunburn. Ask your educator to hand these letters to the principal.

Assessment

LEARNING OUTCOME 2: CONSTRUCTING SCIENCE KNOWLEDGE

The learner will know and be able to interpret and apply scientific, technological and environmental knowledge.

Assessment Standard

We know this when the learner

2.1 recalls significant information.

Memorandum

Write down as many uses for the sun as possible.

  • The sun provides energy for humans, plants and animals.
  • The sun heats the earth.
  • The sun provides light for the earth.
  • The sun keeps us warm.
  • The sun helps plants to grow.
  • Any other acceptable answer.

Hold a group discussion on the damage that the sun can cause to your skin, and then complete the following activities:

1. One’s skin can be burnt very badly by the sun. It can be so severe that blisters can form.

2. Learners cut out pictures and paste them in the spaces provided. They can even bring real products that can be discussed in class.

3. Models who are used in advertisements are always depicted as being beautifully tanned. This puts pressure on ordinary people to try to look like them. (Here one could discuss peer pressure in general.) Any acceptable answer.

4. Let the learners write short letters to give to the principal. Interesting things should come out of this exercise.
