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.

Roofs are sometimes pushed off vertically during a tropical cyclone, and buildings sometimes explode outward when hit by a tornado. Use Bernoulli’s principle to explain these phenomena.

Explain why the change in velocity is different in the two frames, whereas the change in kinetic energy is the same in both.
Fabian Reply
Insulators (nonmetals) have a higher BE than metals, and it is more difficult for photons to eject electrons from insulators. Discuss how this relates to the free charges in metals that make them good conductors.

Is the photoelectric effect a direct consequence of the wave character of EM radiation or of the particle character of EM radiation? Explain briefly.

That's just how the AP grades. Otherwise, you could be talking about m/s when the answer requires m/s^2. They need to know what you are referring to.
