Memorandum

Critical and developmental outcomes:

The learners must be able to:

1. identify and solve problems and make decisions using critical and creative thinking;

2. work effectively with others as members of a team, group, organisation and community;

3. organise and manage themselves and their activities responsibly and effectively;

4. collect, analyse, organise and critically evaluate information;

5. communicate effectively using visual, symbolic and/or language skills in various modes;

6. use science and technology effectively and critically, showing responsibility towards the environment and the health of others;

6. demonstrate an understanding of the world as a set of related systems by recognising that problem-solving contexts do not exist in isolation;

7. reflect on and explore a variety of strategies to learn more effectively;

8. participate as responsible citizens in the life of local, national, and global communities;

9. be culturally and aesthetically sensitive across a range of social contexts;

10. explore education and career opportunities; and

develop entrepreneurial opportunities.

  • Integration of Themes: Autumn
  • A healthy environment: The signs of Autum.
  • This module begins with a graph of birthdays of their friends.
  • Number concept and counting activities, stressing the patterns in counting, are extended to 120.
  • Halving and doubling within the range 1 to 50.
  • Shopping activities include word sums, directions to shops, and selecting the correct coins are included.
  • Learners complete a shopping graph.
  • Bonds of 10, 11, 12, 13, 14 and 15 are introduced and consolidated with a variety of activities.
  • Measuring activities reinforce the vocabulary of “a small mass”, “a great mass”, gram and kilogram.
  • A recipe for muffins is included and learners experience practically the value of measurement (Technology).
  • To extend their sensitivity to different cultures they create their own patterns using shapes and patterns found on huts.
  • Learners learn through playing games and therefore a memory game with number sentences has been designed for them.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
