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 is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
